[0.9.21-beta] - 2026-05-23

Closes out the remaining Tier 3 roadmap items: a third batch of ambient effects + initial Winget manifest scaffolding so the upcoming winget install Delido.SignalRGBWallpaper flow has something concrete to ship.

Added — Ambient effects, batch 3

Twelve presets now in the Configurator → Effects picker. Three new visually-distinct effects, all written from scratch in the AMBIENT_PRESETS shape (no copied code, no per-pen licence verification needed):

• Matrix — falling vertical streams of katakana + digits + symbols, classic green-on-black "digital rain". Each column owns its length / speed / character buffer and periodically swaps a random glyph for the flicker. Tint mode replaces the green palette with the user's glow colour while keeping the head row bright white so the leading edge of each stream still reads against any background.
• Starfield — particles distributed in normalised polar space at varying z-depth; each frame z shrinks (zoom toward viewer), projection puts them at increasing screen radius from the centre with a short streak trail. The trail is the trick that sells the hyperspace illusion. cx / cy baked at spawn so the projection stays stable through the few seconds an average star lives.
• Lightning — brief flashing branched arcs via midpoint displacement (start + end + 4 subdivisions = jagged 17-point polyline; branch jitter shrinks with depth so the macro shape stays close to a straight bolt while micro-segments wobble). Two-phase envelope: hot flash for the first ~70 ms, then squared-fade tail for a real-arc-afterglow look. ctx.shadowBlur halo gives the bolt its glow, reset per draw so it doesn't leak into other presets.

Configurator gains matching mini-preview tiles for all three so the picker reads at a glance.

Added — Winget manifest scaffolding

• New installer/winget/ directory with the three-file v1.6 manifest format for submission to microsoft/winget-pkgs:
• Delido.SignalRGBWallpaper.yaml — version manifest
• Delido.SignalRGBWallpaper.installer.yaml — installer URL + SHA256 (per-release update)
• Delido.SignalRGBWallpaper.locale.en-US.yaml — metadata (description, tags, URLs)
• installer/winget/README.md documents the per-release update workflow + wingetcreate submit invocation. Status note: the scaffolding is in-tree as of v0.9.21; the actual first-time PR to microsoft/winget-pkgs is still a maintainer-todo since it requires a manual review round with the Winget moderators.

[0.9.20-beta] - 2026-05-23

Drops the lazy-loaded ONNX default model entirely. After three attempts at finding a stable, single-file, permissively-licensed hosted model (RMBG-1.4 → Xenova/u2netp → rembg/v0.0.0/u2netp.onnx), all of which failed in different ways (non-commercial licence, external-data split, fetch-blocked), v0.9.20 walks the whole external-fetch path back to pure-JavaScript algorithms running on the canvas. Faster, offline, no licence concerns.

Changed — Builder Auto-cut

• New default mode: "Auto saliency (instant)" — frequency-tuned saliency (Achanta et al. 2009, public-domain algorithm). For each pixel: Euclidean colour distance from the image's mean RGB plus a brightness premium; adaptive threshold. Strong on the "neon panels / UI overlays / glowing edges" wallpaper case because those regions are precisely where the colour deviates most from the image's overall palette.
• "Brightness (Otsu)" stays as the second mode for cases where pure-brightness thresholding fits better (e.g. uniform-coloured panels on a dark backdrop).
• Both modes run in tens of milliseconds, fully offline, no network, no licence considerations.
• "Custom ONNX model" mode is now hidden by default. Users who want it can opt in via localStorage["builder.aiEnabled"] = "1" or by setting a URL in localStorage["builder.aiModelUrl"]. The ORT loader stays in the codebase for that path.

Docs

• docs/credits.md audit refreshed: ORT moved to opt-in section, RMBG / U²-Netp default-URL discussion replaced with the pure-JS algorithm credits (Achanta-2009 saliency + Otsu-1979).
• The earlier v0.9.18 + v0.9.19 betas are kept in Releases this time around (no yank) — v0.9.18's licence-clean Apache 2.0 intent was correct, just had the wrong delivery mechanism; v0.9.19 fixed the auto-update path that all later releases depend on.

[0.9.19-beta] - 2026-05-23

Two real-world bugs from v0.9.18: the new Apache 2.0 default AI model URL pointed at a multi-file Hugging Face host that ORT couldn't auto-resolve, and the tray auto-update STILL aborted silently because Inno's CloseApplications=yes deadlocks under /SUPPRESSMSGBOXES. Both fixed.

Fixed — Builder Auto-cut

• AI default URL now points at the long-standing single-file rembg release asset for U²-Netp (Apache 2.0) instead of huggingface.co/Xenova/u2netp. The HF Xenova host splits the model graph (model.onnx) from the weights (model.onnx_data), and onnxruntime-web doesn't auto-resolve the second file — hence the "failed to load external data file" error in v0.9.18. The rembg URL is a single self-contained .onnx so one fetch is enough. Same Apache 2.0 licence.
• localStorage["builder.aiModelUrl"] override still works for any user wanting a different model.

Fixed — Tray auto-update

• CloseApplications=yes → force in the Inno script. yes shows a confirm dialog asking the user whether to close the running bridge before install. With /SUPPRESSMSGBOXES (set by the silent-update path) that dialog is killed before it renders, leaving the installer waiting on user input that will never come and eventually aborting. force skips the prompt and closes the bridge unconditionally before overwriting SignalRGBBridge.exe. This is the missing piece behind the "starts a window briefly then everything closes" symptom from v0.9.17 + v0.9.18.

[0.9.18-beta] - 2026-05-23

Licence-cleanup release: swaps the AI cut-out default model from RMBG-1.4 (BRIA, non-commercial) to U²-Netp (Apache 2.0). Commercial wallpaper / streaming / studio users no longer get steered into a paid-licence dependency just by clicking AI saliency.

The v0.9.16 + v0.9.17 release tags were yanked from GitHub Releases for the same reason; users on those builds should either wait for their tray auto-update to pick this version up, or manually download the v0.9.18 installer from the latest release.

Changed — Builder Auto-cut

• Default model: U²-Netp (Apache 2.0) at 320×320 input — permissive licence, free for any use including commercial. Replaces the v0.9.16 / v0.9.17 default which was RMBG-1.4 (BRIA RMBG v1.4 License v1.0, non-commercial only).
• The user-facing workflow is identical: pick AI saliency, click Run, get a salient-region mask. The model is smaller (4 MB vs ~44 MB), inference is faster, and there's no licence trap waiting for commercial users.
• localStorage["builder.aiModelUrl"] + ["builder.aiInputSize"] overrides still work if a user wants to point at a different model. Otsu mode is the default-selected option in the picker and uses no model / network at all.

Docs

• docs/credits.md updated: U²-Netp attribution added, RMBG-1.4 warning removed (no longer the default), audit date bumped to v0.9.18.
• README + roadmap re-aligned to the v0.9.x cycle reality (Tier 1 + 2 shipped, Builder Auto-cut shipped, the Builder Wall workflow shipped). Outdated v0.8.0-first-stable language replaced.

[0.9.17-beta] - 2026-05-23

Bug-fix release for v0.9.16's Auto cut tool + the long-standing tray-side auto-update flow. Three concrete issues from real-world use.

Fixed — Builder Auto cut

• AI mode dimension mismatch. Default model is RMBG-1.4 which expects 1024×1024 inputs; the v0.9.16 code fed 320×320 and the ORT session bailed with "Got invalid dimensions for input". Now feeds the model at its native resolution (1024×1024) and exposes both the URL and the input size via localStorage so users can bring their own model:
• localStorage["builder.aiModelUrl"] — full model URL
• localStorage["builder.aiInputSize"] — input H = W (1-2048)
• Undo button stayed disabled after an Auto-cut. runAiCutout was missing the updateHistory() call that every other operation makes, so the history sidebar didn't refresh and Ctrl+Z / the Rückgängig button stayed greyed out. The op was already in the clicks array — only the UI was wrong; existing v0.9.16 sessions can recover by adding any other edit (which triggers updateHistory) then Ctrl+Z'ing twice.
• Dropped the ImageNet-style mean/std normalisation since RMBG-1.4 and the usual U²-Net exports both want raw [0,1] floats; the Threshold slider absorbs any residual per-channel offset.

Fixed — Tray auto-update

• Installer never visibly started after download. The subprocess.Popen(..., creationflags=DETACHED_PROCESS) path was reportedly silently failing on some Windows / SmartScreen setups, leaving the user with a closed bridge and no install. Switched to ShellExecuteW via ctypes — goes through the user shell, SmartScreen gets the right provenance context, and the child is a fully independent process from instruction zero. Subprocess fallback retained if the API call fails.
• /VERYSILENT → /SILENT so the Inno-Setup progress bar is visible during install. The user gets immediate confirmation the install is really running, and any Inno error dialog is shown instead of swallowed.
• Sleep before os._exit bumped 1.5 s → 3.0 s so AV real-time scan of the just-downloaded exe has time to complete before the parent dies.
• Each step now writes to %TEMP%/signalrgb-update.log so future failures are diagnosable post-mortem.

[0.9.16-beta] - 2026-05-23

New Builder tool: Auto cut. One click detects the brightest / most salient regions of the loaded image and cuts them transparent — the typical "I want neon panels to glow with RGB" wallpaper workflow done in a single action instead of dozens of manual clicks.

Added — Builder

• Auto cut tool (✨ icon in the toolbox). Two modes share the same storage + replay path so undo / redo / refine-with-brushes work like any other operation:
• Otsu (instant) — computes the optimal brightness threshold via Otsu's method on a luma histogram of the canvas, then cuts every above-threshold pixel. No internet, no model, no WASM — runs synchronously on the main thread, finishes before the spinner can show. Genuinely good for neon / UI / sci-fi panel imagery where the cut signal is brightness.
• AI saliency (downloads ~7 MB) — lazy-loads onnxruntime-web from jsDelivr and a U²-Netp saliency model from Hugging Face the first time the user clicks Run; both are browser-cached afterward so subsequent runs are local. Inference runs at 320×320; the output is nearest-neighbour upsampled to canvas resolution at draw time.
• Threshold slider biases the mask cutoff ±25 % so the user can soften / aggress the cut without re-running the model.
• Invert toggle flips the mask before applying — useful when the saliency net picks the subject but the user wants the background cut instead.
• Auto-cut operations show up in the History panel like any other click (purple swatch · mask dimensions · invert flag) and rotate correctly with the Rotate 90° button.

Notes

• The U²-Netp model URL can be overridden via localStorage["builder.aiModelUrl"] for users behind a CDN block / on a corporate mirror.
• AI mode needs internet on first use only. After the first successful run, the browser cache holds both the runtime and the model so the tool works offline.

[0.9.15-beta] - 2026-05-23

Second wave of ambient effects — three new presets to keep the Effects picker filling out. All written from scratch in the AMBIENT_PRESETS shape introduced by v0.9.12, so no per-pen licence verification is needed.

Added — Ambient effects

• Plasma — soft full-canvas hue-cycling blobs, lava-lamp style. Each blob owns its hue clock so the colour wash is always shifting. Distinct from aurora (which is confined to a horizontal band). When Tint is on, drops the hue cycle and runs the user's glow colour so the effect stays on-palette.
• Vortex — particles spawn near the canvas edge and spiral inward toward the centre with rising angular velocity, despawning once they get close enough; new ones replace them at the perimeter. Polar-coords internally so the spiral feels stable on resize. Tinted variant uses the glow colour as the particle body.
• Bubbles — hollow-rim circles rising from the bottom with a slight horizontal wobble, growing slightly as they rise. Stroked rather than filled so the background image stays visible inside each bubble; the small specular highlight on the upper-left adds depth.

Configurator's effect picker gains matching tile previews so the preset card looks right at first glance instead of needing the wallpaper page to be visible to judge the effect.

[0.9.14-beta] - 2026-05-23

Builder right-panel rework — fixes the workflow-order + visual-feedback issues that surfaced once Span Canvas landed in v0.9.13. Source comes first, Wall sits second as the climax of the flow, Output is last; the Merge subsection collapses out of the way until it's actually needed.

Changed — Builder right panel

• Reordered: Source (Load) → Monitor Wall → Output. Earlier layout had Wall on top but the user always has to load / merge first, so the eye was jumping bottom-to-top.
• Merge subsection is collapsed by default. Two-image and 2×2 merge controls now live behind a <details><summary> so the single-image happy path doesn't have to scroll past four file-pick slots. The summary line tells you the section exists; clicking expands it inline.
• Wall action hierarchy: "Wand anwenden" is now a full-width, taller primary button. Span Canvas + Clear sit in a secondary row underneath so the climax of the flow is unambiguous.
• Clear button now disables itself when there's nothing staged (prevents the dead-click that previously left wall-stat empty).
• Staged-ready hint ("2/2 Bildschirme bereit — „Wand anwenden" überträgt.") replaces the Span-suggestion banner the moment any slot is filled. Earlier UI kept showing "versuche Canvas spannen" even after the user had just clicked it, which contradicted the apply-success status one line below.

[0.9.13-beta] - 2026-05-22

Closes the Builder merge ↔ Monitor Wall workflow gap (one-click span across monitors) and adds a tray-side hot-reload path so the next time wallpaper-page JS ships in a beta, users don't have to re-import the Lively/WE bundle from scratch.

Added — Builder

• ⇔ Span canvas across monitors. New button in the Monitor Wall toolbar. Slices the current canvas into one chunk per screen, sized proportionally to each screen's physical width, and stages every Wall frame in a single click. Fits the merge two photos side-by-side → 7680×2160 → spread across both 2560×1440 monitors flow that previously needed manual cropping + per-frame canvas grabs.
• Span-suggestion hint under the Wall canvas. Lights up whenever the loaded canvas's aspect ratio is within 5 % of the wall's combined aspect (sum of screen widths over common height), so the user spots the shortcut without reading the toolbar.
• Span button enables only when (a) a canvas is loaded and (b) there are 2+ active screens; tracked via the new updateWallSpanState helper that runs on canvas changes and Apply Wall state ticks.

Added — Tray / Bridge

• "Reload wallpaper pages" entry under tray → Advanced. Bridge pushes {type: "reload"} over the WS to every connected wallpaper page (configurator clients explicitly excluded so an open settings tab doesn't get yanked). The wallpaper page handles the new frame by calling location.reload(). Lets future cosmetic / widget updates land without manually re-importing the Lively / WE bundle for each release.
• Caveat: the listener has to ship in the previous installed version. Wallpapers running from a pre-v0.9.13 bundle still need the one-time manual re-import after upgrade; from v0.9.13 onward the tray button does it.

[0.9.12-beta] - 2026-05-22

Two new ambient effects in the spirit of the planned CodePen ports from the roadmap. Implementations written from scratch to fit our existing AMBIENT_PRESETS shape (no third-party code carried in), so there's no per-pen licence verification to track.

Added — Ambient effects

• Constellation — particles drift across the canvas; thin lines appear between any two particles within a fade radius. Inspired by the classic connect-the-dots effect (ykob/aBrjaR style). Triggered the addition of an optional def.after(ctx, particles, tint) post-pass hook to the ambient renderer so effects can draw across the whole particle set instead of one-at-a-time. Existing presets are untouched (no after defined → no-op).
• Fireflies — slow-drifting glow dots that pulse on their own per-particle phase clocks (yellow-green band by default; Tint with the live glow colour overrides). Pre-tinted variant lands nicely on dark backgrounds.

Both presets appear in the Configurator's Ambient preset tile grid with the same mini-canvas preview the existing effects have.

[0.9.11-beta] - 2026-05-22

Builder Monitor Wall is now the primary right-panel navigation. Each tile pre-fills with its screen's current wallpaper and opens a compact action menu on click; the old Apply to Screen N and Multi-monitor split sections fold into it via Use current canvas.

Changed — Builder right panel

• Monitor Wall promoted to the top. Was buried below Apply / Split; the new order puts it first, matching how multi-monitor workflows actually flow (pick layout → drop image per monitor → Apply).
• Each frame pre-fills with the screen's current bgImage via the /image?path= proxy. Live snapshot of the desktop instead of an empty box. Hover shows "Click to change" hint.
• Bigger frames sized for primary-nav use (130 px wide in horizontal mode, 150 px in 2×2 / free, 220 px in vertical).
• Per-frame click menu replaces the old single-button row:
• 📁 Choose file… — system file picker
• 📚 From library… — same Library dialog Open from library uses
• 🖼️ Use current canvas — snapshots the Builder's canvas (with all in-progress mask edits) into the slot. Replaces the old Apply to Screen N buttons.
• ✕ Clear — drops any staged image, frame reverts to current wallpaper preview. Menu positions below the clicked frame, clamps to viewport, and Esc / click-outside dismiss.
• Apply Wall re-loads /config after success so each frame paints the just-applied background (the bridge stamps a new timestamped filename so the proxy bypasses CEF caches).
• Loaded slot now wears a soft green glow ring so staged-but- not-yet-applied tiles read at a glance.

Removed

• "Apply to screen N" section — folded into the Wall via the Use current canvas menu action.
• "Multi-monitor split" section — replaced by the Wall's horizontal layout. Split-the-canvas-and-send-each-half workflow is now: Wall with horizontal layout → Use current canvas on the left tile → crop canvas to right half → Use current canvas on the right tile → Apply Wall. Fewer one-shot buttons, one workflow.

The two legacy section names (section.apply, section.split) remain in the i18n table for backwards compat but are no longer referenced by any DOM.

[0.9.10-beta] - 2026-05-22

Tier 1 setup-polish slice complete. Adds the two remaining items — Ctrl+Z undo and the first-run onboarding tour — and trims the roadmap of two items that didn't pan out.

Added — Configurator

• Ctrl+Z undo / Ctrl+Y (or Ctrl+Shift+Z) redo for the last 20 setting changes per screen. Per-screen ring buffer captured in setSetting before each write; redo stack invalidates on the next manual edit (linear-history model — same as every editor's undo). Toast on each apply tells the user which key was reverted. Doesn't cover widget add/remove/move, presets, mirror, or cycle — those have their own scoped reversal flows. Reset-this-screen wipes both rings since the prior entries would revert to fields that no longer exist.
• First-run onboarding tour. Fires on first WS settings push when localStorage.signalrgb.tour_seen is absent. Seven steps: Welcome → Tabs → Overview card → Background → Presets → Builder → Done, each with a spotlight ring + floating tooltip pointed at the live DOM element being explained. Skip / Esc / overlay click all dismiss; the Tour button in the header re-fires it on demand.

Removed (roadmap cleanup)

• Mobile Configurator view — niche, would have needed a LAN- bind opt-in with security ergonomics. Most users sit at the PC the wallpaper runs on. Marked 🅿️ parked.
• Community wallpaper gallery — high copyright-infringement risk (unfiltered user uploads of brand IP, anime stills, game art etc.). Moderating a public submission flow would dwarf the curation value. Marked 🅿️ parked. Bundled starter library + per-user upload remain the supported path.

[0.9.9-beta] - 2026-05-22

Quick fix for the Monitor Wall Horizontal row mode rendering as a vertical stack on narrow right-panel widths.

Fixed

• Monitor Wall: horizontal layout now scrolls horizontally instead of wrapping to a column. Previously flex-wrap: wrap on the wall canvas plus 260 px right-panel width meant two ~130 px frames + gap exceeded the available room → second frame wrapped to the next line. New rule pins horizontal mode to flex-wrap: nowrap; overflow-x: auto so the row stays a row and the strip scrolls when it doesn't fit. The 2×2 + vertical layouts keep their existing wrap behaviour.

Roadmap: added a planned Monitor-Wall-as-primary-right-panel-nav redesign for an upcoming release — promotes the Wall to the top of the right panel, pre-fills each frame with the screen's current background, adds a per-frame click menu, and collapses the now- redundant Apply to Screen N + Multi-monitor split sections.

[0.9.8-beta] - 2026-05-22

First Tier-3 item: one-click update install. The tray no longer just links you to the release page — it downloads the new installer and runs it silently while the old bridge bows out, then the new bridge auto-restarts.

Added — Tray

• "⬇ Download + install {tag}" entry at the top of the tray menu, shown whenever an update is pending and the release ships an installer asset (i.e. every official build). The existing "open release page" entry stays for users who want to read release notes first.
• Tk progress window during download — shows percentage and bytes-done / bytes-total. Doesn't auto-close; the process exits when the installer takes over.

Added — UpdateChecker

• Asset URL capture during the daily release-poll: scans assets[] for the canonical SignalRGBWallpaperSetup*.exe name and stores the direct download URL + content-length alongside the release tag.
• download_and_install(on_progress, on_done) — streams the installer into %TEMP%, spawns it with /VERYSILENT /SUPPRESSMSGBOXES /NORESTART (detached + own process group), waits 1.5 s for the installer to grab its handles, then os._exit(0) so it can replace SignalRGBBridge.exe in place.

Changed — Installer

• Dropped skipifsilent from the bridge auto-launch [Run] entry. In silent mode (used by the new tray flow) the bridge now auto-restarts after install; in interactive mode the postinstall checkbox still gates user opt-in.

[0.9.7-beta] - 2026-05-22

Two follow-ups to v0.9.6: keyboard input still didn't reach the in-page prompt under Lively/WE (fundamental CEF wallpaper-window limitation, not a 0.9.6 regression), and the Quote widget's api.quotable.io source has been dead since mid-2024.

Fixed

• Widget gear icons now open the Configurator in a new tab instead of an in-page modal. Lively/WE forward mouse events to wallpaper pages (so the gear click worked) but keyboard events go to whichever window has OS focus — the wallpaper is never the foreground window, so typed characters never reached the in-page input. The 0.9.6 wpPrompt overlay looked right but silently dropped keystrokes.
• Each built-in widget's editOptions now points at a single openWidgetInConfigurator(rec) that does window.open("/configurator?editWidget=<id>&editScreen=<n>").
• Configurator parses those query params on load, switches to the matching screen tab, and opens the existing options modal for that widget id once the WS settings push arrives. Query params are stripped from the URL on first read so a hard reload doesn't re-fire the modal.
• Quote widget — bundled local quote list. api.quotable.io has been DNS-dead since mid-2024 (every fetch errored, every Quote widget rendered "couldn't fetch a quote"). Now ships with 50 curated public-domain quotes (Einstein / Twain / Tolkien / da Vinci / Linus / Knuth / Dijkstra / …). No external HTTP call — works under WE's CEF block on outgoing fetch too. Per-tick refresh logic still picks a fresh entry per day. via Quotable footer removed.

[0.9.6-beta] - 2026-05-22

Hotfix for widget gear-icon dialogs freezing the wallpaper page.

Fixed

• Widget edit-options dialogs froze the page when the user clicked a widget's gear icon. Built-in window.prompt() / alert() calls block the JavaScript thread and, under Lively/WE's CEF, occasionally render the dialog behind the wallpaper or fail to dismiss — locking the entire page.
• wpPrompt(label, default) → Promise<string|null> and wpAlert(message) → Promise<void> — in-page replacements rendered as a small DOM overlay (HTML inputs + OK/Cancel buttons) styled to match the wallpaper UI. Enter / Esc / click-outside dismiss; resolves with the entered value or null on cancel.
• All built-in widgets (clock, calendar, weather, sticky note, countdown, picture frame) converted to async editOptions using the new helpers. Their gear icons now open an in-page modal instead of the browser's native prompt.
• Click handler for the gear icon learned to .catch the returned Promise so async rejections surface in the console instead of dropping silently.

[0.9.5-beta] - 2026-05-22

Fourth and final Tier-2 high-visibility feature: per-app / per-game profiles. When a matching .exe is in the foreground, the bridge auto-applies a preset slot; reverts cleanly when the foreground changes away. Pro-tier USP against ordinary wallpaper tools.

Added — Bridge

• ProfileWatcher — 1 Hz foreground-window poller. Reads the active window via Win32 GetForegroundWindow → QueryFullProcessImageNameW, extracts the basename, and matches it (case-insensitive) against the user-configured config.profiles rule list.
• Activation snapshot — on first match, the watcher snapshots every target screen's current settings before applying the rule's preset. On deactivation (foreground exe no longer matches any enabled rule), the snapshot is restored via PRESET_SNAPSHOT_KEYS so only the preset-relevant fields revert — the user's mirror setup, viewport, etc. stay intact.
• One active rule at a time — when the foreground switches from rule A's exe to rule B's exe, A reverts first (with A's snapshot) before B activates (with a fresh snapshot of the now-current state).
• Rule CRUD — add_profile / update_profile / remove_profile, routed via new profile-add / profile-update / profile-remove WS commands. Each mutation persists config.json and re-pushes every screen's settings so other open Configurator tabs sync.
• Mirror-aware: the watcher relies on apply_preset which is blocked on mirrors via _block_if_mirror; the source screen's preset apply propagates to mirrors through the existing _replicate_to_mirrors path.

Added — Configurator

• Per-app profiles card at the bottom of the main column, collapsed by default. Each rule row carries:
• Enable checkbox
• Exe field (e.g. cyberpunk2077.exe, case-insensitive)
• Optional human-readable label
• Target screen — All screens or a specific tab
• Preset slot (1..4)
• Delete button (with confirm)
• Add rule… button appends a default-shaped rule (example.exe, all screens, slot 1) that the user then edits in place.
• Live sync — the profiles list rides alongside data in every settings push, so two open Configurator tabs stay in sync.

[0.9.4-beta] - 2026-05-22

Third Tier-2 high-visibility feature: now-playing widget. Reads Windows' SystemMediaTransportControls so the title + artist of whatever the user is listening to (Spotify, Groove, browser HTML5 audio, Edge, anything that publishes SMTC) shows up on the wallpaper.

Added — Bridge

• NowPlayingPoller — dedicated asyncio-loop thread polls GlobalSystemMediaTransportControlsSessionManager.request_async every second, captures the current session's media properties (title / artist / album), playback status, and timeline (position / duration). Snapshot is merged into SysStatsPoller's payload as nowPlaying so the wallpaper page gets the data through the existing 1 Hz WS push.
• winrt-Windows.Media.Control + winrt-Windows.Foundation + winrt-runtime bundled via PyInstaller --collect-all winrt. When the package isn't present (older Python or build skipped the dep), the poller logs a notice and stays a no-op so the rest of the bridge keeps running.

Added — Widget catalog

• now-playing widget type registered in three places: bridge WIDGET_DEFAULTS, configurator WIDGET_CATALOG, wallpaper WIDGET_REGISTRY. Options:
• Show progress bar (thin bar across the bottom, animates with track position).
• Show artist line (second line under the title).
• Tint with glow colour (progress bar borrows the live tint).
• Auto-hide when no media session is active: title fades to "—" with reduced opacity instead of leaving an empty widget in the layout. Playback paused → title dims to 55 % opacity as a visual hint.

[0.9.3-beta] - 2026-05-22

Second Tier-2 high-visibility feature: global preset hotkeys. Ctrl+Shift+1..4 applies the matching preset slot on every active screen at once — full desktop look swap in a single keystroke.

Added

• HotkeyListener background thread on the bridge — registers Ctrl+Shift+1, Ctrl+Shift+2, Ctrl+Shift+3, Ctrl+Shift+4 via Win32 RegisterHotKey on its own thread, pumps GetMessage, and on WM_HOTKEY fires apply_preset on every active screen for the matching slot. Mirrors are skipped by the existing _block_if_mirror guard, so they update via replication from their source instead of locally.
• Tray toggle under Advanced → Preset hotkeys (Ctrl+Shift+1..4). Checkmark reflects the live state. Off by default so we don't grab shortcuts the user might have wired up elsewhere — flip it on once and it persists across restarts via config.presetHotkeysEnabled.
• Graceful unregister on toggle off: Stop() posts WM_QUIT to the listener thread which unregisters all hotkeys before returning, so other apps can reclaim the shortcuts cleanly.

[0.9.2-beta] - 2026-05-22

First Tier-2 high-visibility feature: wallpaper auto-cycle. Each screen can rotate through its library on a schedule, picking sequentially or randomly from the full library or pinned-only pool.

Added — Bridge

• CycleScheduler — single background thread, 30 s tick, walks every screen and fires the next library entry through _update_background when cycle.enabled is true and at least intervalMin minutes have passed since the last apply.
• Mirror-aware — mirrors are skipped explicitly so the source's cycle drives them through the existing _replicate_to_mirrors path; the mirror doesn't get its own scheduler tick.
• Persistent bookkeeping — cycle.lastApplyMs and cycle.nextIdx live inside the config and survive a bridge restart, so the rotation picks up where it left off.
• Partial-merge update path — _update_cycle merges incoming config changes onto the existing cycle dict so the configurator can send just enabled or intervalMin without zeroing the scheduler's pointers. Pool / order values are whitelisted.

Added — Configurator

• Auto-cycle block at the bottom of the Background card:
• Enable checkbox
• Interval (1-720 min)
• Pool — All library or Pinned only
• Order — Sequential or Random
• Hint line that counts down "Next change in {n} min" between settings pushes (re-painted every 30 s without a full settings roundtrip)
• Cycle settings are not mirrored — every mirror still picks up whichever wallpaper the source's cycle chose, since the resulting bgImage replicates through the normal mirror path.

[0.9.1-beta] - 2026-05-22

Monitor Wall gains a Free-form layout option — drag each monitor frame to any position on a workspace, so non-standard setups (e.g. one portrait monitor between two landscapes, L-shape, etc.) can be arranged visually before applying.

Added — Builder

• Free-form Monitor Wall layout. New option in the layout dropdown next to Horizontal row, 2×2 grid, Vertical column.
• Frames sit on a fixed-height workspace with a subtle 20 px grid background so positions feel deliberate.
• Mouse-down on a frame → drag to reposition. Frames are clamped inside the workspace so they can't drift off the edge.
• Drag is differentiated from click: small movements still open the file picker (no false positives), real drags suppress the click for 100 ms after release.
• Positions persist in localStorage keyed by screen count so a layout for 2 monitors survives switching temporarily to 3 and back.
• New Reset positions button (visible only in free-form mode) wipes the saved layout and re-fans to a default horizontal arrangement.

[0.9.0-beta] - 2026-05-22

Builder gains a Monitor Wall section: visual layout of every connected screen with per-tile image picker and a single Apply Wall batch upload. Generalises the per-screen Apply buttons + Split tools into one workflow that matches how users actually think about multi-monitor wallpapers.

Added — Builder

• Monitor Wall section (right panel, below Multi-monitor split).
• Layout dropdown: Horizontal row (1×N), 2×2 grid, Vertical column (N×1). Slot count derives from the live screenCount in /config.
• Frame aspect ratios use each screen's reported viewportW/H so an ultrawide tile actually renders ultrawide. Falls back to 16:9 when no wallpaper page has connected to that screen yet.
• Per-frame image pickers: drop a file on a frame, click the frame to pick from disk, or hit the Library hover-action to pull from the Configurator library — same dialog the existing Open from library… button uses.
• Apply Wall batch-uploads each loaded slot to its matching screen via the existing POST /screen/<N>/background endpoint. Empty slots skip — lets the user push only the screens they care about. Re-encodes through canvas → PNG so JPEG/WebP inputs land in a consistent format.
• Clear resets every slot in one click.
• Layout / viewport state is re-polled every 10 s, so changing screen count or monitor resolution updates the Wall section without a reload.

[0.8.10-beta] - 2026-05-22

Two fixes against the v0.8.9-beta System-status dialog: plugin file not found on OneDrive-redirected Documents folders, and the Configurator's own WS tab inflating the "connected pages" count.

Fixed

• System status: SignalRGB plugin file shown as missing even though the installer dropped it correctly. On Windows installs with OneDrive Documents redirection, Path.home() / "Documents" resolves to an empty/legacy folder while Inno Setup's {userdocs} token routes through SHGetFolderPath and writes to the actual OneDrive-backed path. New _candidate_documents_dirs helper walks (in order): HKCU\Software\Microsoft\Windows\ CurrentVersion\Explorer\Shell Folders\Personal (the value Windows uses internally, matches {userdocs}), then any ~/OneDrive*/Documents and ~/OneDrive*/Dokumente siblings, finally plain ~/Documents / ~/Dokumente. The dialog now finds the plugin file in the same folder the installer wrote it, and the Open plugins folder button opens that location.
• System status: "Connected pages" count off by one (or more). The Configurator's own open browser tab opens a WebSocket and was counted as a wallpaper page, so a user with two monitors who had the Configurator open saw "3 connected pages" instead of 2. WS clients now declare a role query parameter (wallpaper by default, configurator for the settings UI); the status dialog counts only wallpaper-role clients. Wallpaper-page WS clients without an explicit role default to wallpaper so legacy pages keep counting correctly.

[0.8.9-beta] - 2026-05-22

Tier 1 setup-polish bundle: tray System-status dialog with one-click Fix buttons, full Backup / Restore via ZIP, and Reset-this-screen on each tab. Plus a translation-key audit that fixed the presets.slot_label regression.

Added — Tray

• System status… dialog. New tray entry opens a Tk window with one green/red row per "is the install actually working?" signal: SignalRGB plugin file present, SignalRGB.exe running, bridge port reachable, wallpaper pages connected, LibreHardwareMonitor reachable (only when a Hardware-sensor widget exists). Each red row offers a contextual Fix button — Open plugins folder, Download SignalRGB, Open Help, Download LHM. Refresh button re-checks without closing.

Added — Configurator

• Backup & Restore card at the bottom of the main column. Export everything… downloads a signalrgb-wallpaper-backup-<ts>.zip containing config.json, the full library/ folder, and the per-screen screens/ backgrounds. Restore from ZIP… uploads the archive back and the bridge replaces config.json, merges library + screens files on top of the live dirs (won't nuke files that aren't in the ZIP), rebuilds the catalogue, and pushes fresh settings to every connected wallpaper page.
• Reset this screen… button on every tab (in the mirror bar). Restores every mirrorable setting to its DEFAULT_SCREEN_SETTINGS value while preserving the screen's viewport, preset slots, and mirror state. Confirmation dialog with explicit "what gets wiped" text. Hidden while the screen is in mirror mode.

Added — Bridge

• GET /backup — streams a ZIP of config.json + library/* + screens/*. Sets Content-Disposition: attachment; filename=... so the browser saves it directly.
• POST /restore — accepts a ZIP body (100 MB cap), validates it has a parseable config.json with the expected schema, then extracts library/* and screens/* paths into their respective folders with path-traversal guards. Replaces the live config, rebuilds the library catalogue, and pushes settings to every screen.
• get_health_status — process check (signalrgb substring in any running process name), plugin file check (~\Documents\WhirlwindFX\Plugins\SignalRGB_Desktop_Wallpaper.js), WS-connected-page count, LHM sensor count, hardware-sensor widget detection. Powers the new tray dialog.
• reset_screen — restores defaults for one screen, preserves viewportW/H, mirrorOf, presets. Routed via the new screen-reset WS command.

Fixed

• presets.slot_label translation missing — the static "Slot 1/2/3/4" labels rendered as raw uppercase keys when the data-i18n attr ran without a matching translation entry. Added the key plus a generic data-i18n-<name> attribute path so any HTML element can carry positional params for its translation template (used by Slot {n}; the pattern is now available for any future parameterised label).

[0.8.8-beta] - 2026-05-22

Closes the Workflow-polish slice with Mirror mode, plus a Builder 2×2-grid merge and a tooling fix from beta feedback.

Added — Configurator

• Mirror mode per screen. A new bar above the section cards carries a Mirror: dropdown — pick Independent (the default) or Mirror Screen N to lock this screen's settings in lockstep with another screen's. On activation the bridge copies every mirrorable key from the source onto self; thereafter every mutation of the source replicates to the mirror via _replicate_to_mirrors. The mirror's section cards visibly disable (.cards-disabled) and reject edits at the bridge level too — a stale tab or future REST client can't drift a mirror away from its source. The overview card marks mirroring tiles with a small chevron badge.
• Mirror invariant enforced server-side. Per-screen mutations (setting-update, widget add/remove/update, widget lock, preset-apply, background upload) all run through _block_if_mirror before touching state. Chained mirrors (A → B → A, or A → B → C) are rejected at activation time so the propagation graph stays a flat star.

Added — Builder

• 2×2 grid merge. Merge images section gains a mode dropdown: 2 images side-by-side (the original) or 2×2 grid (4 images). In grid mode four slots (TL / TR / BL / BR) become available, each with the same file picker / drag-drop / From library… button as the existing pair. Output forces equal-size quadrants; the cell dimensions match the largest input on each axis so neither half loses resolution.

Fixed

• Tool-options column too narrow for long localised button labels. Widened from 232 px → 260 px so "Alle Änderungen zurücksetzen" and friends fit cleanly without bumping into the canvas border.

[0.8.7-beta] - 2026-05-22

Two of the three remaining Multi-monitor-convenience items from the Workflow-polish slice. Mirror mode is the only Workflow-polish entry still outstanding (deferred to v0.8.8-beta because it needs bridge-side invariant enforcement that wants its own focused beta).

Added — Configurator

• Apply to all screens — per section. Each Background / Glow / Effects / Widgets card header now carries an Apply to all button (visible only when screenCount > 1). Click → confirm → the current screen's values for that section's keys get POSTed to every other screen. Each section declares its own key set so the one button works for one card without leaking into others.
• Overview card with mini-monitor thumbnails. New row between the tab strip and the first card (hidden for single-monitor setups). One 130 × ~73 px thumbnail per screen showing the current background image with a resolution overlay. Click jumps to that screen's tab. Active screen gets a brighter border + 2 px glow ring. Driven by the same /config poll that feeds the tab resolution labels — single fetch, both views consistent.

Bridge

• POST /screen/<N>/settings — batch setting update on screen N. Body is a JSON object of {key: value} pairs; each key is filtered through the same _SETTABLE_SCREEN_KEYS whitelist the WS setting-update command uses, so the HTTP path adds no attack surface. Used by the Configurator's Apply-to-all flow because the WS connection is bound to one screen at a time.
• /config returns per-screen bgImage alongside viewportW/H. Used by the Overview card to paint mini-thumbnails without opening a WS per screen.

[0.8.6-beta] - 2026-05-22

Hotfix: installer was overwriting the user's library.json, which hid uploaded wallpapers from the Configurator until the user uploaded another image (forcing the bridge to rebuild the catalogue from disk).

Fixed

• Library tiles missing after an installer-driven upgrade. The installer's [Files] section shipped a bundled library.json listing only the four starter wallpapers and overwrote the user's own catalogue on every install. The PNGs were still on disk, but the bridge's /library/list endpoint just returned whatever library.json said — so user uploads vanished from the strip (re-appearing on the next upload because that path regenerates library.json from the directory contents).
• Bridge: rebuild the library catalogue once at startup. This repairs any state where library.json is out of sync with the actual files (installer overwrite, manual file copy, sync conflicts). _library_rebuild_catalogue already preserves pinned/order/addedAt for entries that survived.
• Installer: split the library [Files] entry into two — PNGs always copy (so users who deleted a starter get it back), but library.json now uses onlyifdoesntexist so it's installed on first install only and never overwritten on upgrade.

[0.8.5-beta] - 2026-05-22

Bug-fix-and-polish pass over v0.8.4-beta plus the Builder crop tool. Heavier multi-monitor items (Mirror mode, Apply-to-all, Overview card) are deferred to a future beta because they need careful invariant work on the bridge side.

Fixed

• Glow preview painted on top of the canvas instead of through the transparent regions. ::before lived above the canvas in the positioned stack; isolation: isolate on .canvas-host plus z-index: -1 on the glow layer scopes it correctly behind the canvas content without escaping past the host's own box.
• Tool panel buttons clipped past the column edge for long localised labels (e.g. "Alle Änderungen zurücksetzen" in the narrow 232 px Tools column). .btn-row .btn now allows wrap + min-width: 0 so labels break to a second line instead of overflowing.

Added — Builder

• Library picker on Merge slots A and B. From library… button next to each Pick file picker opens the same modal grid the Open from library… button uses; the picked tile lands in the merge slot rather than the main canvas.
• Crop tool. New toolbox entry (icon: crop corners). Drag a rectangle, then Confirm to resize the canvas to that region — pulls pixels through a scratch canvas so all in-progress mask edits survive. Click history resets on commit since the click coords no longer match. Switching tools mid-pending-crop cancels the rectangle.

Added — Configurator

• Tab labels show resolution when a wallpaper page has connected for that screen — "Screen 2 — 3840×1080" instead of bare "Screen 2". Falls back to the bare label when no page is connected yet. Polls /config every 5 s so a monitor switching resolution shows up without a hard refresh.

[0.8.4-beta] - 2026-05-22

Closes the Workflow-polish slice on the Gallery side and lands the long-promised Builder Show glow preview toggle. Multi-monitor convenience (Mirror mode, Apply-to-all, overview card, tab resolutions) is the focus of the next beta.

Added — Configurator library

• Pin to top. New Pin / Unpin entry in the right-click context menu. Pinned tiles render first, ahead of starters and uploads, with a small star badge in the upper-left corner. Persisted as pinned: true inside library.json; bridge merges the flag back into the catalogue on every directory rescan (upload / rename / duplicate / delete no longer wipe pin state).
• Sort order: pinned → user order → newest → label. The strip now sorts by: pinned first, then user-set order from drag-reorder, then addedAt descending (newest upload bubbles up), then label alphabetical as a stable tie-break. addedAt is stamped on every entry from file mtime so fresh uploads sort correctly even before the user touches anything.
• Drag-and-drop reorder. Each tile is draggable=true. Drop on the left/right half of a target tile to insert before/after with a visible drop-indicator (4 px coloured edge). New order POSTs to /library/reorder which assigns sequential order indices in library.json. Works across pinned + unpinned items.

Added — Builder

• Show glow preview toggle in the canvas toolbar (right side, next to the canvas-stat). Swaps the canvas's transparency checkerboard for an animated RGB-cycle gradient layered behind, so cut-out pixels show what the SignalRGB glow will look like as you edit. Off by default (the checkerboard is still the canonical view for spotting unintended transparency).

Bridge

• POST /library/pin — body {file, pinned}, toggles the pin flag on one entry without re-scanning the directory.
• POST /library/reorder — body {order: [file1, file2, …]}, assigns sequential order indices to listed entries; unlisted entries are pushed past the end so they stay reachable.
• _library_rebuild_catalogue preserves user-state fields (pinned, order, addedAt) across rebuilds. addedAt is stamped from file mtime for fresh entries.

[0.8.3-beta] - 2026-05-22

Workflow polish for the Configurator's Library and the Builder — first half of the planned Workflow polish slice from docs/roadmap.md. Makes browsing, picking, editing, and saving library wallpapers feel like a real gallery instead of a click-and-pray strip.

Added — Configurator library

• Hover preview popup. Hovering a library tile opens a larger 16:9 preview (480×302) anchored to the tile, with an animated RGB gradient layer behind. Since wallpapers carry transparent cut-outs (the entire point of this app), the gradient bleeds through and previews how the SignalRGB glow will look once paint lands on top. Auto-dismisses with a small grace period when the mouse leaves; Escape, scroll, or click-outside also dismiss.
• Click-to-preview (pinned). Clicking a tile no longer immediately replaces the screen's background. Instead the preview pins open — auto-hide on mouseleave is disabled while pinned, and a dedicated Apply button inside the popup actually commits. Removes a long-standing footgun where a stray click could wipe the current wallpaper.
• 5-second Undo toast. When a library item is applied, the toast shows for 5 s with an inline Undo button. Clicking Undo POSTs the previously-active background bytes back to the screen. We snapshot the bytes via the /image?path=… proxy before the new POST — necessary because the bridge deletes the old screen-N-*.png file on each apply, so the only way to recover is to capture the bytes first.
• Right-click context menu on every tile with: Apply · Edit in Builder… (opens /builder?library=<file>) · Rename… (prompts for new label, re-uploads + deletes old) · Duplicate (creates <label> Copy) · Delete… (existing confirm dialog). Menu auto-clamps to the viewport and closes on Escape, scroll, or click-outside.

Added — Builder

• Open from library… picker. New button next to Choose image… opens a centred modal grid of every library tile. Click one to load it as the source image — same code path the file-picker uses, so edits / merges / saves work identically. Reads /library/list on open (no caching).
• Save to library button. Once an image is loaded, the new Save to library button POSTs the current canvas to /library/upload?name=… with a prompt-supplied label, defaulting to the source filename. Useful for round-tripping a Builder edit back into the Configurator's library strip without going through the OS file system.
• ?library=<file> URL parameter. Builder honours ?library=foo.png on load and fetches that file from /library/ through the standard pipeline. Used by the Configurator's Edit in Builder… context-menu item.

Internal

• Reusable preview popup / context menu / library dialog. Each is a single DOM element built on first use and re-used across invocations (item, position, label). Click-outside / Escape / scroll dismissal is centralised. No per-tile listener leaks on renderLibraryStrip re-renders.

[0.8.2-beta] - 2026-05-20

Adds an optional integration with LibreHardwareMonitor for the hardware-sensor widget family, plus folds in the v0.8.1 perf fix-up that was sitting un-tagged.

Added

• Hardware Sensor widget. New generic widget type that reads any sensor LibreHardwareMonitor is reporting — CPU / GPU temps, fan RPMs, voltages, drive temps, power readings, etc. Picks the sensor from a dropdown that's populated dynamically from a new GET /hwmon/sensors endpoint, with live current-value previews next to each path so you can find what you're looking for. Sparkline tracks last ~2 min @ 1 Hz. Optional label override and decimals control per widget. LHM is not bundled — users who want temps/fans install LibreHardwareMonitor separately (free, MPL 2.0) and enable its Options → Remote Web Server. When LHM isn't running the widget shows — and the sensor dropdown shows (LHM not detected — see Help → Tips). Help page has a step-by- step setup section under Tips. License audit + docs/credits.md entry added; MPL 2.0 doesn't propagate because we don't redistribute any LHM files.
• /hwmon/sensors HTTP endpoint on the bridge — returns a flat sorted list of every sensor (path, current value, unit) plus a status block (online, sensorCount, lastError). Used by the Configurator's options modal; could also drive future Hardware Monitor dashboards from external tools.

Fixed (from the unreleased v0.8.1 perf work)

• SignalRGB-startup lag. SignalRGB fires every onXChanged callback once per ControllableParameter while a plugin initialises — for our plugin that's ongridSizeChanged, onaspectRatioChanged, oncustomColsChanged and oncustomRowsChanged, each of which used to call applyZoneSize directly. Combined with the one applyZoneSize from Initialize(), every device rebuilt its device.setControllableLeds registry five times in a row at startup. For an ultrawide on Auto + base=64 that's 5 × 14592 = ~73k LED operations per device per startup — and SignalRGB's JS sandbox is single-threaded across all plugins, so the whole tick stalled until ours finished.
• The four onXChanged exports now set a module-scope dimsDirty flag instead of calling applyZoneSize directly. Render() coalesces the burst into a single rebuild on its next tick.
• applyZoneSize itself gained an early-bail: if the resolved dimensions match the current s.cols/s.rows and the frame buffer is already allocated, it returns immediately — the expensive setControllableLeds call is skipped.
• The /config poll only flips dimsDirty when the viewport for a screen actually changes (was: flip on every 2 s poll while Aspect = Auto, causing redundant rebuilds).
• Render() no longer calls computeGridDimensions() on every frame — that was 30 fps × N devices = 120 calls / s of small but pointless arithmetic on the steady-state path.

Together these are the difference between "noticeable hitch when SignalRGB starts" and "no hitch at all" on the 4-monitor / ultrawide setup.

[0.8.1] - 2026-05-20 (never tagged — folded into 0.8.2-beta)

[0.8.0] - 2026-05-20

First stable after the long 0.7.x beta cycle. Rolls up every feature from v0.7.1-beta → v0.7.10-beta (full-screen audio glow, auto-Lively bootstrapper, library upload / delete, pattern brush, 4-monitor support, ultrawide aspect ratios, configurator + builder localisation, single-bundle Wallpaper Engine packaging, …) plus the items below.

Added

• In-browser Help page. New /help route serves a scenario-based walkthrough — Quick start + 1/2/3/4 monitor setups for both Lively and Wallpaper Engine (independent vs single-bundle vs spanned), ultrawide aspect notes, and a Tips & common pitfalls section. Pure HTML, no dependencies beyond what's already bundled. Full DE / EN — language pulled from GET /config like Builder.
• Tray menu gains a Help… entry alongside Configurator… and Build Wallpaper…. Opens /help in the user's default browser.
• Optional help-images folder. Each scenario card carries an <img> placeholder under /help/images/<name>.png. Bridge serves whatever's in %LOCALAPPDATA%\SignalRGBWallpaper\help_images\ (user override) or wallpaper_bridge/help_assets/ (dev fallback). Missing images hide silently (no broken-image icons) — the ASCII diagrams in each card stand alone if no screenshot is provided.
• docs/installation.md gains a screenshot walkthrough of every Inno Setup wizard step (language → license → tasks → summary → file-in-use → finish). README quick-start links to it.

Changed

• Installer task defaults cleaned up. Install the SignalRGB Desktop Wallpaper plugin keeps its default-on state but the description now flags it as required, and it sits at the top of Additional setup instead of buried below the autostart/configurator toggles. Users who casually uncheck it currently end up with a bridge but no SignalRGB → bridge path; the new wording makes the consequence obvious.
• Removed the redundant "Open Wallpaper Engine projects folder" post-install action for the auto-copy-detected case. When both Steam and WE are detected, the bundle is already in place and shows up in WE's My Wallpapers tab — opening Explorer to confirm a file landed there was filesystem-debug noise, not a normal user need. The not-detected fallback (where the user does need to drag a folder into WE manually) stays.

[0.7.10-beta] - 2026-05-20

Fixed

• WE audio fix from v0.7.9-beta was set on the wrong JSON node. v0.7.9-beta added "supportsaudioprocessing": true at the project root, but WE only honours it as a child of general (verified against real Workshop wallpapers, e.g. IPdotSetAF/NeoMatrix). Moved to the right place — wallpaperRegisterAudioListener callbacks finally fire under WE.

[0.7.9-beta] - 2026-05-20

Fixed

• Audio still dead in Wallpaper Engine. v0.7.8-beta fixed Lively via LivelyInfo.Arguments = "--audio", but WE has an analogous opt-in: project.json must declare "supportsaudioprocessing": true or the engine ignores every wallpaperRegisterAudioListener callback. Our project.json didn't set it, so the audio-glow layer + audio-spectrum widget saw no FFT samples on WE. Added to the build's combined-bundle manifest generator. (v0.7.10-beta caveat: the flag was put on the top-level node here — WE silently ignored it. Real fix is in 0.7.10-beta.)

[0.7.8-beta] - 2026-05-20

Sweep of user-reported papercuts plus the last open roadmap item.

Added

• Auto-Lively bootstrapper. Closes the last Planned roadmap item: when the user opts in and Lively isn't detected, the installer downloads the latest Lively setup from GitHub Releases and runs it silently before the auto-import [Files] step. Driven by a new bundled install_lively.ps1; fails closed (no kill of the wizard) if GitHub is unreachable. New Inno [Tasks] entry installlively/autoinstall (sub-task of Lively Wallpaper, default on).
• Library upload + delete in the Configurator. Bridge gains POST /library/upload?name=<label> (raw PNG / JPEG / WebP body) and DELETE /library/<file>. Configurator's Background section shows an Add image… button next to the strip; each tile has a hover-only × delete corner. Library catalogue is rebuilt on every mutation so the strip refreshes immediately.

Fixed

• Audio listener never fired in Lively. LivelyInfo.Arguments was null since v0.7.1-beta (after the --system-cursor true fiasco), but Lively only pushes audio data when the wallpaper opts in. Set to "--audio" (the documented Lively flag) so both the whole-screen audio glow layer AND the audio-spectrum widget actually receive FFT samples on Lively. WE users were unaffected.
• Configurator status badge showed connected · tray.screen_n. The template called t("tray.screen_n", …) but tray.screen_n only exists in the bridge's tray-side translation table, not the Configurator's. Replaced with a dedicated conn.connected entry ("connected · Screen {n}" / "verbunden · Bildschirm {n}").
• Configurator tabs for inactive screens stayed visible (dimmed). Switched to display: none so a 1-screen install only shows Screen 1. Lowering the screen count while a higher tab is active falls back to Screen 1 automatically.
• Hover-glow Pixelfx rendered as a square in some CEF builds. The radial-gradient fillRect was technically alpha-0 at the corners but the CEF compositor was rendering the rect bounds anyway. Switched to ctx.arc + ctx.fill — guaranteed circle.

Changed

• Inno installer task defaults pass. Wallpaper Engine now defaults to checked (was unchecked) — undetected Steam installs are still no-ops thanks to the Check: WallpaperEngineDetected gating, so the default-on doesn't risk anything. New optional task Open the Configurator in your browser when done (default on). Description wording for Auto-import + Start bridge on logon tightened.

[0.7.7-beta] - 2026-05-20

Added

• Per-screen preset slots in the Configurator. Four numbered slots per screen, each saving a snapshot of every settable field in PRESET_SNAPSHOT_KEYS (background image / fit / dim, glow layout / strength / blurs, all ambient + pixelfx + parallax + audio-glow knobs, and the full widget array including positions and options). New WS command types: preset-save / preset-apply / preset-clear. Bridge runtime gains matching save_preset / apply_preset / clear_preset methods. UI: collapsed-by-default Presets section above Background with one row per slot showing a short summary (widget count, layout, active effects). Pre-v0.7.7-beta configs auto-pad to four empty slots on next load.
• Pattern-fill brush in the Builder. New tool button in the toolbox (dots glyph) — instead of clearing a solid hole, paints transparency in a structured pattern. Three pattern types: Halftone (dot grid, dot radius modulated by density), Dither (ordered Bayer 8×8 threshold matrix), Hatching (parallel lines at a chosen angle and spacing). Scale (2..32 px), Density (5..95 %), Angle (0..180°) sliders. Reuses the existing brush size / hardness / shape options. Pattern coordinates are absolute-canvas-based, so adjacent strokes tile continuously instead of restarting per stamp. Stored as a new kind: "pattern" click record so undo / redo / rotate-90° work consistently with the other tools.
• Wallpaper library. Four procedurally generated starter wallpapers (cyberpunk skyline, neon grid, anime round window, geometric panels) ship with the installer, dropped into %LOCALAPPDATA%\SignalRGBWallpaper\library\ together with a library.json manifest. The Configurator's Background section gets a Library strip of thumbnail tiles; clicking one uploads the full-res PNG to the active screen via the same POST /screen/N/background endpoint the Builder uses. Bridge serves the listing + files at /library/list and /library/<file> with path-traversal protection (no .. / slashes in filenames). Users can add their own PNGs to the same folder; the bridge enumerates whatever's there.

Changed

• Plugin log spells out what Auto resolved to. applyZoneSize used to log just aspect=Auto. Now it appends either (viewport 3840x1080) if the bridge has seen a real viewport push from the wallpaper page, or (no viewport from bridge — 16:9 fallback) if not. Turns "why are my LEDs 7296 instead of 14592?" into a single-grep diagnosis in SignalRGB_*.log.

[0.7.6-beta] - 2026-05-20

Tiny plugin-side fix: SignalRGB's layout editor was rendering our LED cells as rectangles because the plugin declared a 1:1 visual aspect while sending non-square LED grids at runtime.

Fixed

• SignalRGB layout editor stretched LED cells horizontally. export function Size() is the device's visual aspect ratio in the canvas — SignalRGB locks the on-canvas bounding box to that ratio and stretches whatever runtime device.setSize([cols, rows]) pushes to fit it. Our plugin used to declare [32, 32] (1:1), which made e.g. a 32×8 runtime grid render as 4:1-stretched cells. Changed to [16, 9] so 16:9 monitor users (the dominant case) finally see square LED cells. Ultrawide / portrait users will still see some stretching in the editor but far less than before, and the actual glow output to the wallpaper page is unaffected — only the SignalRGB-editor preview was wrong.
• DefaultScale() dropped from a suspicious 60.0 to 1.0 (full-canvas default when the device is first dropped). Pre- existing user placements are not touched; this only affects fresh adds.

[0.7.5-beta] - 2026-05-20

Ships the long-standing roadmap item Whole-screen audio-reactive glow layer. The audio-spectrum widget covered "audio visualiser in a box" since 0.6.0-beta; this adds a full-canvas counterpart.

Added

• Audio-reactive glow layer behind the wallpaper. Reuses the same FFT feed the audio-spectrum widget already drains (Lively's livelyAudioListener / WE's wallpaperRegisterAudioListener), so no second registration is needed. Three modes:
• Pulse — overall amplitude drives a smoothed radial halo breathing outward from the centre.
• Spectrum bars — 64 bars rising from the bottom edge.
• Waveform — symmetric line through the screen's centre, amplitude-modulated. Configurator's Effects section gains a Audio glow dropdown + Intensity slider + Tint with the live glow colour toggle. Canvas uses mix-blend-mode: screen so it adds light over the underlying glow instead of replacing it.
• Settings keys whitelisted: audioGlow (off/pulse/spectrum/wave), audioGlowIntensity (0..100), audioGlowTint (bool). Defaults: off / 60 / false.

[0.7.4-beta] - 2026-05-20

Retires the legacy Tk Settings dialog: every knob it owned moved into the in-browser Configurator. Builder window joins the DE / EN localised UI.

Added

• Configurator owns Number of screens. A small picker lives in the tab bar's top-right ("Screens: 1 / 2 / 3 / 4"). Clicking sends a new WS command type bridge-setting-update to the bridge, which persists the value to config.json and re-pushes settings to every connected Configurator so all open tabs stay in sync. Tabs beyond the active count are visually dimmed (clickable, but the matching SignalRGB device isn't announced).
• Configurator owns Show debug overlay. Per-screen checkbox in the Background section, wired through the existing setting-update showStatus path.
• GET /config exposes the active UI language alongside screenCount + screens[]. The Builder fetches it on load.
• Builder is DE / EN. Its own TRANSLATIONS map + t() + applyI18n() (same shape as the Configurator), covering every visible label, tooltip, hint, and toast message. Language source is the new /config field.

Changed

• Tray menu retires the Legacy Settings dialog… entry. Every knob the dialog owned now lives in the Configurator (per-screen settings already moved in 0.6.0-beta; screenCount + showStatus finished the move in this beta). The SettingsDialog class stays in bridge.py as dormant code in case a future workflow needs a no-WebView fallback, but no menu entry reaches it.
• Architecture doc updated to reflect the threading model now having one tk.Tk() user — the About dialog — instead of two.

[0.7.3-beta] - 2026-05-20

Adds auto-cleanup of the legacy per-screen Wallpaper Engine folders on upgrade — previously you had to delete them manually. Same packaging as v0.7.2-beta otherwise (single combined WE bundle with a Screen index property).

Changed

• Installer wipes legacy WE folders before copying the new bundle. Inno Setup's [InstallDelete] removes SignalRGB_Glow_Screen{1..4}/ from both the install staging folder ({app}\Wallpaper Engine wallpapers\) and — when Steam is detected — Steam's …\projects\myprojects\, gated on the WE task. Pre-v0.7.2-beta users upgrading via the new installer get a clean WE library automatically. The per-screen items were never published to Steam Workshop, so the installer is the only path that ever placed those folders.

[0.7.2-beta] - 2026-05-20

Wallpaper Engine packaging consolidation: one Workshop item with a Screen index property replaces the four per-screen bundles. Folds in everything from v0.7.1-beta (4-monitor support, ultrawide aspect ratio, Lively-import hotfix, Weather widget cache fix).

Changed

• Single Wallpaper Engine bundle. The installer now copies wallpaper_bridge/we_bundles_single/signalrgb-glow/ into both {app}\Wallpaper Engine wallpapers\signalrgb-glow\ and (when Steam is detected) …\steamapps\common\wallpaper_engine\projects\myprojects\signalrgb-glow\, instead of four per-screen folders. Subscribers assign the same wallpaper to every monitor they want to drive and pick a different Screen index (Screen 1 / 2 / 3 / 4) per assignment in WE's properties panel. The bridge already routed by ?screen=N query param, so this is a packaging change only — no protocol change.
• installer/build.ps1 drops step [3b/5] (per-screen WE bundle staging) entirely; the legacy wallpaper_bridge/we_bundles/ folder is wiped on each build so it can't accidentally feed stale sources into the installer.
• Uninstaller removes the new signalrgb-glow/ folder AND the legacy SignalRGB_Glow_Screen{1..4}/ folders, so upgrades from earlier beta installs leave a clean Steam projects folder.

[0.7.1-beta] - 2026-05-20

Folds the Lively-import hotfix into a beta that also lifts the long-standing MAX_SCREENS = 3 cap to 4. Released as a prerelease — stable users with Allow beta versions off won't see it as an update.

Added

• 4-monitor support. The bridge's N_SCREENS, the SignalRGB plugin's MAX_SCREENS, the Configurator's tab generator, the Builder's Apply to screen + Multi-monitor split button rows, the installer's auto-import / WE-bundle copies, and the single-WE- bundle's screenIndex combobox all moved from 3 → 4. Bridge config migration is data-driven on N_SCREENS, so existing config.json files gain the Screen 4 settings block on next launch without losing anything.
• Build emits 4 Lively zips + 4 WE folders. installer/build.ps1 iterates 0..3 for the per-screen Lively and WE stagers; installer copies / auto-imports / uninstaller entries all extended.
• Non-square glow grids for ultrawide monitors. The SignalRGB plugin gained an Aspect Ratio dropdown (Auto / 1:1 / 16:9 / 21:9 / 32:9 / 9:16 / Custom) and Custom Cols / Custom Rows textfields. Auto reads each screen's actual viewport (the wallpaper page already reports it over WS; the bridge now relays it through GET /config in a new screens[] sidecar) and derives the longer side from the Glow Grid Base Size combobox so a 3840 × 1080 panel gets base × (base · 3840/1080) instead of a square that under-samples its width. The wire format already supported arbitrary W × H frames; the wallpaper page reads --cols / --rows per frame, so no client-side change was needed.

Fixed

• Lively import failure (carried over from the local v0.7.1 hotfix that was never published). LivelyInfo.Arguments reverted from "--system-cursor true" to null. Parallax + Pixelfx still receive cursor coordinates via the DOM mousemove listener whenever Lively's Wallpaper interaction setting is enabled (or the page is loaded in WE / a browser). Pure click-through users no longer get cursor-driven effects, which is a knowable trade-off and far less bad than a broken wallpaper.
• Weather widget always showed Berlin. When the user edited the location through the Configurator, the widget's rec.cache (last fetched payload, including the label) and rec.lastFetch timestamp (30-min refresh cap) were never invalidated, so the next render still showed the old data and the next tick wouldn't re-fetch for up to half an hour. applyWidgetOptions now stores a signature of the previous options and drops cache + fetch timer whenever it changes, forcing an immediate re-fetch on edit. Fix is generic — countdown / quote / any future cached widgets benefit.

[0.7.0] - 2026-05-19

First stable release after a long beta cycle (0.5.0 → 0.6.2-beta). Rolls in everything from the beta line plus the polish iteration on top of 0.6.2-beta: auto-import into Lively, chunked UDP transport (real 128 × 128 grids), DE / EN localisation, About-dialog overhaul, snap-to-grid in the configurator, 3D parallax, and a convenience top-level Lock/Unlock entry in the tray.

Added

• Wallpaper reports its real viewport to the bridge. Page sends {type:"viewport", w, h} on WS open + on window.resize (debounced). Bridge persists per-screen viewportW / viewportH. Configurator's layout-preview scales to the actual monitor — 4K users now see a real 3840 × 2160 canvas instead of a guessed FullHD rectangle, and the preview header reports the source (monitor · 3840 × 2160 px vs no wallpaper connected — assuming 1920 × 1080). Disk-write is skipped when the size matches the persisted value.
• Top-level Lock / Unlock widgets in the tray. Single entry above the Advanced submenu that toggles widgetsLocked across every active screen at once. Label flips (🔓 Lock widgets (all screens) / 🔒 Unlock widgets (all screens)) based on current state.
• Snap-to-grid in the Configurator's layout preview. Toggle + step picker (10 / 20 / 40 / 80 px); the preview canvas overlays the snap grid in accent blue when enabled. Drag and resize both snap to the chosen step. State persists in localStorage so it survives reloads.
• About dialog overhaul. Now shows the maintainer's real name (Sebastian Mendyka) with a clickable @Delido on GitHub line and the avatar fetched from https://github.com/Delido.png (5 s timeout, cached). The wall-of-OSS text has been moved to docs/credits.md on GitHub — the dialog now links there instead. Added a "Buy me a coffee" PayPal button.
• 3D parallax (parallax3d, CSS px max-displacement, 0..120). When > 0 the background image lerps a fraction of the cursor offset for a fake-depth effect. Cursor coords flow from two sources: Lively's livelyCurrentCursorPos callback (pushed by the host when available) and a DOM mousemove listener that catches real events when Wallpaper interaction is enabled. Scale-up of the bg image is computed per frame so the worst-case translate doesn't reveal edges, with 2 % headroom for jitter. Smooth RAF lerp; disabled (no rAF cost) when off. Slider lives in the Configurator's Effects section. Same dual cursor feed also covers Pixelfx.
• Chunked UDP transport. The SignalRGB plugin sandbox caps udp.send() at 4 096 B per datagram, which had pinned us at 36 × 36 grids. The plugin now sends frames > 4 KB as multiple datagrams with a new SC magic ([0x53][0x43][screen][frameId] [chunkIdx][chunkCount][w₂][h₂][pixelOffset₂][rgb…]); the bridge buffers chunks per (screen, frameId) and reassembles before forwarding to the wallpaper page. Stale partials (different frame-id or > 200 ms old) are evicted. Wallpaper-side renderer is unchanged. MAX_GRID raised from 36 to 128; combobox gains 64 / 96 / 128. Backwards-compatible — anything ≤ 36 × 36 still uses the original single-packet SR format.
• Installer auto-imports Lively wallpapers. New opt-in sub-task "Auto-import into Lively (skip the manual drag-and-drop step)". When checked and a Lively install is detected — GitHub build (%LOCALAPPDATA%\Lively Wallpaper\…) or MSIX build (%LOCALAPPDATA%\Packages\rocksdanister.LivelyWallpaper_*\…) — the three bundles get extracted directly into Lively's Library\wallpapers\signalrgb-glow-screen-{1,2,3}\. Deterministic folder names mean every subsequent installer run overwrites in place, killing the "delete + re-import after every update" caveat that bit every release until now. Uninstall removes the three folders, leaves other Lively wallpapers alone.
• Localisation — DE / EN. New top-level config flag language: "auto" | "en" | "de" (default "auto" — picks from Windows locale / $LANG). Bridge exposes a tr(key, **kwargs) helper backed by a single in-file translation table; tray menu, Updates submenu, Effects submenu, Widgets submenu, About dialog and balloon notifications are all translated. Configurator mirrors the same pattern (data-i18n attributes + t() helper); the active language arrives with every settings push from the bridge so the page localises on first frame. Builder window stays English — its ~80 strings are tracked as a separate follow-up.

[0.6.2-beta] - 2026-05-19

Prerelease. Adds 36×36 as the finest packable grid; 64×64 was tried and reverted because of a SignalRGB sandbox limit (see below).

Added

• Glow Grid Size combobox gains 36 alongside 8 / 16 / 32. 36×36 fits exactly under SignalRGB's per-packet UDP cap (36×36×3 + 7 B header = 3 895 B); going any higher requires chunked transport.

Known limit

• SignalRGB's udp.send() is capped at 4 096 B per datagram, well below the IPv4 UDP-payload ceiling. We attempted 64×64 (= 12 295 B per frame) and immediately saw udp.error - Buffer too large. Max size is 4096 bytes! in the SignalRGB log with no frames reaching the bridge. MAX_GRID in SignalRGB_Desktop_Wallpaper.js is therefore 36. A future iteration could split each frame across multiple datagrams (the bridge would reassemble) for true 64+ grids.

[0.6.1-beta] - 2026-05-19

Prerelease. Configurator UX polish on top of 0.6.0-beta.

Changed

• Configurator: prominent lock / unlock toggle. The widgetsLocked switch was an easily-missed checkbox; it's now a full-width lock-bar at the top of the Widgets section with a coloured status dot, a big label ("Widgets locked" / "Widgets unlocked"), and a clear action button ("Unlock to edit" / "Lock widgets"). Single source of truth — flipping it pushes the same state to the live wallpaper.

Added

• Layout preview in the configurator. New canvas under the lock-bar showing the screen as a scaled rectangle (auto-fits to the bounding box of all widgets or 1920×1080, whichever is bigger) with each widget rendered as a draggable + resizable box. Pointer events drive drag / resize; min size 60×60 px; positions clamp to the canvas. On release, the configurator sends the same widget-update command the wallpaper page uses, so the live wallpaper jumps to match. Drag / resize only active when the lock-bar is unlocked — locked state shows the layout as a static read-only view.

[0.6.0-beta] - 2026-05-19

Prerelease. The three-phase effects roadmap landed in one drop, plus a brand-new in-browser configurator. Tray → Updates → Allow beta versions to opt in.

🎛️ Added — In-browser configurator

New page at http://127.0.0.1:17320/configurator, opened by the tray's primary Configurator… action. Replaces the per-screen Widgets / Effects right-click submenus (which had become an unusable maze of radio submenus) with a single tabbed UI:

• Per-screen tabs at the top, one WebSocket per active tab.
• Background section — image path field, file-picker (re-uses the builder's PNG-via-canvas upload to the bridge's existing POST /screen/N/background endpoint), Fit dropdown, Dim slider.
• Glow section — layout dropdown, strength / grid-blur / stripes-blur sliders, show-bars toggle.
• Effects section — five live mini-canvas tiles for the ambient presets (snow / rain / sparks / aurora actually animate inside the tile so you see what each preset looks like before applying), tint toggle, density slider, pixelfx segmented buttons.
• Widgets section — list of all placed widgets per screen with icon + label + short description; Configure opens a real form-based modal (no more prompt() chains) built from a per-type option schema; Remove button per row; an "Add" picker-grid with all registered widget types.
• New WebSocket command setting-update so the page can drive any non-widget per-screen setting. Server-side whitelisted to prevent random config keys from being mutated.

Tray menu was simplified to: Configurator… (default click) · Build Wallpaper… · Advanced submenu (legacy Settings, quick-add widget / effect submenus, reload config) · Updates · About · Quit.

🎆 Added — Ambient effects (Phase 2)

Four full-canvas particle presets that run behind the widgets:

• Snow — soft drifting flakes with sideways wobble
• Rain — diagonal lines, density-driven
• Sparks — warm hot-core embers floating up
• Aurora — large soft hue-shifting blobs drifting across the screen

Hand-rolled canvas engine (no extra JS dependency — the existing interact.js is enough). All four presets honour an opt-in "Tint particles with glow colour" toggle that pulls the already-computed glow average and recolours the particles.

Tray → Effects → Screen N → pick the preset (radio), toggle tint, and adjust density (1..100; defaults to 60). Live-pushed — toggling visibly changes the wallpaper without reconnecting anything.

📊 Added — System-stat widgets (Phase 3)

Four new widget types appended to the registry:

• CPU meter — current %, plus a 120-second sparkline
• RAM meter — same shape for memory pressure
• Network graph — current ↓ / ↑ rates (human-formatted B/s · KB/s · MB/s) over a dual-line chart, auto-scaled to the rolling max
• Audio spectrum — bar visualizer driven by Lively's livelyAudioListener (and Wallpaper Engine's wallpaperRegisterAudioListener). 64-bar FFT, scales with widget size; falls back to "waiting for audio…" when nothing is playing

CPU / RAM / Net stats come from a new SysStatsPoller thread in the bridge — uses psutil (BSD-3-Clause, bundled into the PyInstaller exe via --collect-all psutil), polls at 1 Hz, pushes a single WebSocket frame {type:"sysstats", data:{cpu, ram, netDown, netUp, uptime, ts}} to every connected wallpaper. The bridge gracefully no-ops if psutil is missing at import time (dev python bridge.py on a box without the module still boots; widgets render "n/a").

Audio doesn't need a bridge hop — Lively / WE inject FFT directly into the wallpaper page.

✨ Added — Pixelfx (Phase 4)

Cursor-following eye-candy on its own canvas layer above the widgets:

• Mouse trail — a fading line of tinted dots
• Hover glow — a soft radial gradient that follows the cursor
• Click ripple — concentric circle on each click
• All — combine the three

Position arrives via Lively's livelyCurrentCursorPos(x, y) callback, so trail + glow work under click-through too. Ripples need real clicks, which means Lively / WE wallpaper-interaction has to be enabled — flagged in the tray menu entry's label.

Added — Tray plumbing

• Effects submenu with per-screen radio lists for ambient preset and pixelfx mode + tint toggle. Auto-generated from AMBIENT_PRESETS_TRAY / PIXELFX_MODES_TRAY constants, so adding another preset later is one tuple in each list.

Removed

• Network widget pulled from this release after testing — the dual-line chart layout needed more work and the rate readings were flaky on some Windows network-interface combos. The bridge still pushes netDown / netUp in the sysstats frame, so a future iteration can bring the widget back without a protocol change.

Changed

• About dialog now credits psutil (BSD-3-Clause).
• New top-level per-screen settings: ambientEffect, ambientTint, ambientDensity, pixelfx. Backfilled on existing configs.

[0.5.3-beta] - 2026-05-19

Prerelease. Hotfix release for the v0.5.2-beta installer.

Fixed

• Wallpaper Engine bundles were not actually copied into Steam when the WE task was selected. The Inno Setup file entries for the Steam-side copy carried an external skipifsourcedoesntexist flag that I'd added without thinking. external in Inno Setup means "look for this file at install-time at the source path" — i.e. the file isn't bundled in the installer at all and was expected to magically exist on the user's disk. Dropped both flags so the bundles are now actually packed into the installer and the {code:GetWallpaperEngineProjects} destination receives them.

Changed

• Installer wallpaper-host selection is now explicit. Both Lively and Wallpaper Engine are opt-in tasks grouped under a single "Wallpaper host:" heading on the Tasks page. Lively stays checked by default; Wallpaper Engine stays unchecked.
• Every follow-up action is gated on the chosen host:
• Lively zips are only copied to {InstallDir}\Lively wallpapers\ if the Lively task is checked.
• WE bundles are only copied to {InstallDir}\Wallpaper Engine wallpapers\ (and the Steam-side projects folder, when detected) if the WE task is checked.
• Start-menu shortcuts for each wallpaper folder only show for the selected host(s).
• The end-of-install "Open folder" prompts only show for the selected host(s) — a Lively-only user never sees a Wallpaper Engine prompt and vice versa.
• Smarter post-install prompt for WE users. If Steam + Wallpaper Engine were detected, the prompt now opens Steam's WE projects folder (where the bundles actually live, ready to assign in WE → My Wallpapers). If WE wasn't detected, it falls back to the local staging folder under {InstallDir} so the user can drag the folders into WE manually. Different wording in each case so the user knows what they're looking at.

[0.5.2-beta] - 2026-05-19

Prerelease. Tray → Updates → Allow beta versions to receive notifications about further beta drops; stable users are unaffected.

Added

• Wallpaper Engine support. The wallpaper bundles are now produced in two formats during build: the existing Lively .zip files and a Wallpaper Engine Web project folder per screen (with a project.json manifest). The page-side HTML already had Wallpaper Engine's wallpaperPropertyListener shim, so no runtime changes were needed — only packaging.
• Installer integration. New opt-in task "Install for Wallpaper Engine" (unchecked by default).
• When checked and a Wallpaper Engine install is detected, the three bundles get copied straight into Steam's …\steamapps\common\wallpaper_engine\projects\myprojects\ — after install you'll find them in Wallpaper Engine's My wallpapers tab, ready to assign per monitor.
• When unchecked or Wallpaper Engine isn't detected, the bundles still land under {InstallDir}\Wallpaper Engine wallpapers\ so you can drop them in by hand later.
• Steam install is detected via HKCU\Software\Valve\Steam → SteamPath. Off-drive Steam libraries are picked up by parsing libraryfolders.vdf, so Wallpaper Engine on a secondary drive still works.
• Uninstall cleanup removes the three Steam-side bundle folders it placed (leaves any other Wallpaper Engine wallpapers alone).
• A new Start-menu shortcut for the Wallpaper Engine wallpapers folder, mirroring the existing Lively one.

Notes

• This release adds Wallpaper Engine support alongside Lively, not instead of it. Lively remains the recommended free host; Wallpaper Engine is a paid Steam app (~€4) and only kicks in if you already own it.
• If the widget weather / quote fail to load inside Wallpaper Engine: enable internet access for the wallpaper in Wallpaper Engine's Browser settings (WE's CEF blocks outgoing requests by default for some users; Lively is more permissive).

[0.5.1-beta] - 2026-05-19

Marked as a prerelease on GitHub. Stable users won't be auto-notified about this build; toggle Allow beta versions in the tray's Updates submenu to opt in.

🚀 Performance

• GPU load on the grid layout: ~20 % → ~3 %. A real measurement on the v0.5.0 → v0.5.1 jump, ≈ 85 % reduction. The big win was killing the transition: background 0.08s linear on individual grid zones — at 60 fps the bridge already delivers smoother colour changes than the tween could, and the compositor was juggling hundreds of in-flight animations every frame. Also: per-zone style writes go through style.background directly instead of style.setProperty("--c", …), and grid zones got contain: strict so style recalcs don't ripple out of their cell. Stripes / pills layouts are unchanged (few enough zones that the original transitions don't show up in the profile).

Added

• In-app update checker in the tray. Polls https://api.github.com/repos/Delido/signalrgb-wallpaper/releases on startup (after a 12 s settle) and once a day thereafter. When a newer release is published, the tray shows a balloon notification and an ⬆ Update available: vX.Y.Z — open release page entry appears at the top of the tray menu. Click → release page in your default browser; download + run the new installer yourself (no unattended auto-update — keeps antivirus quiet, gives you the choice).
• Updates submenu in the tray:
• Check for updates now — manual trigger.
• Enable update checks — master switch (default on).
• Allow beta versions — include GitHub prereleases in the comparison (default off). Toggling triggers an immediate re-check so you see the new candidate without waiting.
• Status line: "Up to date — last checked …", "Last check failed: …" or "Not yet checked". Plus an "Installed: vX.Y.Z" line.
• Semver-aware version comparison (MAJOR.MINOR.PATCH plus optional -prerelease suffix). Prereleases sort before the matching stable per semver, so 0.5.1-beta < 0.5.1 — stable users won't be nagged about betas.

• Two new top-level config keys: updateCheckEnabled (default true) and allowBetas (default false). Backfilled on existing configs.

• Four more widget types (continuing the 0.5 series): Sticky note (double-click in edit mode to type inline; four colour variants), Countdown (target date + label, smart unit pick), Picture frame (URL or local path, three fit modes, optional rounded corners), Quote of the day (fetched daily from Quotable, CC BY-SA — attribution in the widget footer).

• In-page widget picker — floating card at the bottom of the wallpaper in edit mode; lists every registered widget type as an icon button. Generated from the same registry the renderers use.
• Per-widget options editor — each widget that takes settings shows a ⚙ button in edit mode (next to the ×). Prompt-driven config for clock style, calendar week start, weather location/units, note colour, countdown target/label, picture URL/fit.
• Extensible widget registry in wallpaper/index.html — one map with {label, icon, markup, mount?, tick, editOptions?} per type. Adding a widget = one entry here + one default in bridge.py's WIDGET_DEFAULTS. Tray "Add…" submenu and the in-page picker both auto-iterate.

Changed

• Bridge tray "Widgets" submenu generated from WIDGET_DEFAULTS instead of hard-coded clock / calendar / weather entries.
• Edit-mode banner replaced by the picker, which carries the bedienanleitung too ("drag · resize · ⚙ configure · × remove · lock in tray").
• Drag-from-button filter — interact.js ignores drags that start on the gear / × buttons or inside a [contenteditable="true"] region, so typing inside a sticky note doesn't move the widget.

[0.5.0] - 2026-05-19

Added

• Placeable widgets on the wallpaper. First slice of the v0.5 widgets roadmap. Three built-in types ship in this release:
• Clock — analog (SVG, 12 ticks, smooth-sweep seconds) or digital (HH:MM:SS + long weekday/date), 24 h or 12 h.
• Calendar — current month grid, today highlighted, week-start configurable (Mon / Sun).
• Weather — fetched from Open-Meteo (free, no API key). Temperature, condition (WMO code → label), "updated N min ago" footer. Defaults to Berlin; per-instance lat/lon configurable.
• Drag-and-resize widget editor on the live wallpaper. Tray menu gains a per-screen Widgets submenu: pick "Edit widgets on this screen" to enter edit mode (handles + delete buttons appear, banner tells you what to do), pick again to lock. Add widgets via "Add clock / calendar / weather" — they spawn at default positions and immediately unlock edit mode so you can place them. Drag-and-resize uses interact.js 1.10 (MIT), bundled into the Lively zip — no CDN dependency at runtime.
• Glow-tinted widgets (opt-in per widget via options.tintFromGlow). When enabled, the widget picks up an average of the current SignalRGB glow colours and applies it through a --w-tint CSS variable (analog seconds hand, digital time, today-cell highlight, temperature). Off by default.
• Two-way WebSocket protocol. The bridge now decodes masked text frames from the wallpaper page and routes the four widget mutation commands (widget-add, widget-remove, widget-update, widgets-lock) into a thread-safe BridgeRuntime API that mutates settings.json and re-broadcasts. Same pipe used today for settings push from bridge → page; just opens the return direction.
• New per-screen settings fields:
• widgets: array of {id, type, x, y, w, h, options} entries.
• widgetsLocked: True (default) or False. Drag/resize is disabled while locked; the wallpaper renders widgets read-only.

Changed

• Broadcaster.__init__ takes a new on_widget_command callback that forwards parsed widget commands to the runtime; the constructor signature change is internal but worth noting if you embedded the bridge.

[0.4.5] - 2026-05-18

Changed

• Builder UI restructured GIMP-style. The single-sidebar wall of controls is replaced by a four-column layout: a vertical icon toolbox on the left (inline-SVG buttons for each of the 6 tools), a Tool Options panel that shows only the sliders/hints relevant to the currently active tool, the canvas in the centre, and a dedicated Files panel on the right with Load / Merge / Output / Apply / Multi-monitor-split sections. Active tool is highlighted; switching tools also updates the panel title and the visible option group.
• Dead .radio-list CSS removed, plus a few orphan styles from the old layout.

Added

• Live brush cursor. While the Restore brush is active the canvas shows a circle (or square) outline that follows the pointer, sized to 2 * brushSize * zoom in CSS pixels — so what you see is the area a click would actually affect. An inner dashed ring marks the hard-core radius at the current Hardness setting.
• Brush hardness slider (0–100). 100 = fully hard edge (legacy behaviour); lower values fade the alpha linearly from the hard-core radius out to the outer radius. Overlapping stamps within a stroke max-merge their alpha so soft edges don't punch holes in each other.
• Brush shape selector (Round / Square). Segmented buttons in the brush options; square brush uses Chebyshev (max-axis) distance for the same falloff model. Both shapes survive a 90° rotate.
• Erase brush. Seventh tool — opposite of the Restore brush. Drives pixel alpha down toward zero with the same size / hardness / shape controls (shared with Restore). Soft edges use min-merge so a hard centre stays fully transparent even if later overlapping soft stamps would otherwise ramp it back up. Live cursor and history rendering match the Restore brush.
• Drag-and-drop on the Merge slots. Both image-A and image-B pickers now accept a dropped image with a visual hover state, matching the canvas's existing DnD.
• Full Undo / Redo history. New Redo button next to Undo; any fresh edit clears the redo stack so we can't resurrect stale operations after the user branches off. Keyboard shortcuts: Ctrl+Z for undo, Ctrl+Y or Ctrl+Shift+Z for redo. The Reset-edits button now stacks everything onto the redo pile, so even Reset is undoable.

[0.4.4] - 2026-05-18

Added

• Merge two images side-by-side in the builder. New block under Step 1 with two file slots ("Pick image A…", "Pick image B…") plus a "Force 50/50" toggle. The default mode matches heights and keeps both aspect ratios (output width = sum of scaled widths); 50/50 stretches each half to equal width — perfect input for the existing multi-monitor vertical split. The merged canvas runs through the same edit / save / apply / split pipeline as a single loaded image, so all tools (polygon, ellipse, restore brush, etc.) work on it unchanged.

Changed

• Internal: loadFile() refactored to a small fileToImage() Promise helper + a shared applySourceImage(name, source) entry point. Both the single-image picker and the new merge button funnel through the same code, which is also where future "open from URL / clipboard" sources would slot in cleanly.

[0.4.3] - 2026-05-18

Fixed

• Settings dialog buttons no longer disappear off the bottom of the window. Save / Close are now in a sticky bottom bar packed before the notebook (side="bottom" first), so they remain anchored no matter how the window is resized or how many sliders are visible on a tab.

Changed

• Settings dialog UX overhaul. Each setting now has a bold label, the control, and a short help-text paragraph underneath explaining what the knob actually does. The tab content is wrapped in a scrollable canvas (mouse-wheel works while the pointer is over it), so the per-screen panel fits any window size cleanly. Default window size bumped to 740×720, resizable down to 620×540.
• Global "SignalRGB device count" and "Auto-pause" sections each got the same help-text treatment so it's obvious what each does.

Added (docs)

• README Gallery section now shows four real screenshots: the in-browser builder, the Lively library with branded tiles, the SignalRGB device list, and the SignalRGB device-settings page.

[0.4.2] - 2026-05-18

Added

• Auto-pause on fullscreen — the bridge now polls Windows once a second via GetForegroundWindow + GetMonitorInfo and broadcasts a {"type":"paused",...} WS frame to all wallpaper pages when a fullscreen app (game, video player, RDP session, anything covering its entire monitor) becomes / leaves the foreground. The wallpaper pages flip into paused state — red "⏸ PAUSED" badge top-right, and renderFrame() short-circuits, so the glow freezes on its last drawn colours. As a bonus the bridge also stops forwarding the per-frame UDP→WS binary broadcasts while paused (SignalRGB plugin keeps sending, bridge just absorbs — saves a bit of CPU during long gaming sessions).
• Tray Settings → Auto-pause section with a checkbox "Pause glow when a fullscreen application is active". Default on; toggle off and the bridge ignores fullscreen state changes.
• SignalRGB_LivelyPauseTester.zip — diagnostic wallpaper. Big PLAYING/PAUSED screen with a panel showing three independent detection paths (Lively's livelyWallpaperPlaybackChanged JS hook, HTML visibilitychange, and a requestAnimationFrame tick-rate probe). Useful to verify your Lively build pauses Web wallpapers at all before filing an issue.
• Lively tile thumbnail — wallpaper_bridge/wallpaper/thumbnail.png generated by installer/generate_thumbnail.py, referenced from LivelyInfo.json so the Library tile is branded instead of plain black.
• rAF tick-rate probe in the wallpaper HTML as a defensive fallback that catches OS-level rendering pause when neither Lively's JS hook nor visibilitychange fire.

Changed

• LivelyInfo.json: Arguments is now null (was "--pause-event true"). The hook was unreliable across Lively builds and the auto-pause is owned by the bridge now anyway.
• build.ps1 regenerates the thumbnail + packages a separate SignalRGB_LivelyPauseTester.zip artefact in addition to the three per-screen zips.

[0.4.1] - 2026-05-17

Added

• Restore brush tool in the wallpaper builder. New "Restore brush" radio in the tool list; "Brush size" slider (3–120 px, default 20). Click+drag over a transparent area to paint the original pixels back to opaque. The stroke previews live as you drag — the brushed pixels' alpha gets restored from the pristine ImageData immediately, no wait for the full mask recompute. On mouseup the whole stroke is committed as a single restore history entry, undoable as one operation.

Fixed

• Wallpaper builder: when zoomed in beyond viewport size, the canvas area now actually scrolls. Was caused by a chain of default min-{width,height}: auto on the grid/flex layout that let the canvas expand its parents instead of triggering overflow: auto scrollbars. Fixed by adding min-width: 0 to the canvas-area grid cell and flex: 0 0 auto to scroll children — both standard Chromium workarounds.

Changed

• applyMask rewritten to be order-sensitive per-pixel (was bucketed-by-kind). This is what makes the restore brush compose correctly with subsequent removals: remove → restore → remove-again works because clicks are processed in order, with restore setting alpha back to the original and a later removal still able to clear it. The previous bucketed pass would have applied restore as a final override regardless of position. Same big-O complexity; tiny bit more per-pixel work for edits with many history entries.
• Rotation rotates restore-stroke coordinates the same way it rotates region / polygon / ellipse coords, so the brush survives a 90° turn.

[0.4.0] - 2026-05-17

Added

• Inno Setup installer (SignalRGBWallpaperSetup-0.4.0.exe, ~21 MB). Per-user install (no admin), copies the bridge to %LOCALAPPDATA%\Programs\SignalRGBWallpaper\, optionally installs the SignalRGB plugin into Documents\WhirlwindFX\Plugins\, drops the three Lively wallpaper zips in a subfolder, registers an HKCU\Run autostart entry, and creates an Add/Remove Programs uninstaller. Two opt-in tasks: "Start bridge automatically on logon" and "Install the SignalRGB plugin into the WhirlwindFX Plugins folder". Build via installer/build.ps1 (one-shot icon + exe + zips + Inno Setup compile). See building-from-source.md for the manual build path.
• Builder: polygon tool. New "Polygon" radio in the tool list. Click corners on the canvas to build the polygon outline; drag any corner handle to reshape; right-click a corner to delete it (with at least 3 corners remaining); drag the polygon body to translate the whole shape. Confirm/Cancel toolbar floats at the top-right of the canvas (fixed positioning so it's always reachable). Enter confirms, Esc cancels.
• Builder: ellipse tool. New "Ellipse" radio. Drag a bounding-box rectangle to lay out an axis-aligned ellipse; four N/E/S/W handles let you resize independently; drag the ellipse body to translate it. Confirm/Cancel as for polygon.
• Builder: "Click in region" tool. Drag a rectangle to set a yellow-dashed region of interest. Subsequent clicks inside that region pick a colour AND restrict its colour-match to within the region — useful for "remove this colour but only on this part of the image". The region persists across clicks until you drag a new one, switch tools, or change images.
• About dialog now shows OSS attribution: Python (PSF), Python stdlib, pystray (LGPL 3.0), Pillow (MIT-CMU/HPND), PyInstaller (GPL 2.0+ with linking exception), tkinter, plus an explicit note that builder.html is vanilla HTML5/JS with no third-party libraries. Build tooling (gh CLI, git, winget, Inno Setup) listed separately as not-shipped.

Changed

• Builder shape-toolbar is now position: fixed (top-right, 60 px below page header) so Confirm/Cancel never slips off-screen.
• applyMask extended to handle four shape kinds (color, region, polygon, ellipse) and an optional region constraint on color entries. Single-pass per pixel; region-restricted color entries short-circuit when out of bounds.
• Rotation now rotates polygon/ellipse coordinates and region-restricted color clicks by 90° CW so masks stay in place relative to the rotated image. In-progress shape edits are cancelled on rotate (their coords would be in stale orientation).
• Tool change clears the bounded region overlay so it doesn't linger after switching to a non-bounded tool.

[0.3.0] - 2026-05-17

Added

• In-browser wallpaper builder. New tray menu item "Build Wallpaper…" opens an HTML5-canvas image editor at http://127.0.0.1:17320/builder in the user's default browser. Pure client-side editor, no extra install needed. Features:
• Drag-and-drop or file picker to load PNG / JPEG / WebP / GIF / BMP.
• Two tools: "Click pixel" (removes globally-similar colours) and "Drag rectangle" (removes a region you select).
• Tolerance slider (0–200) tunes the colour-match width; tweaking after a click live-updates the most recent match.
• Soften edges option adds a 2 px feathered rim around transparent cut-outs so they don't look pixelated under the CSS blur.
• Undo / Reset for non-destructive iteration (the pristine original is kept in memory).
• Rotate 90° for portrait/landscape mismatches; click history survives.
• Zoom controls (− / + / Fit / 100%) and Ctrl+wheel.
• Output size cap (default 4K) so saved PNGs don't run to 50 MB+ on 8K source images.
• Save as PNG downloads via the browser.
• Apply directly to Screen 1 / 2 / 3 buttons POST the current image to the bridge — wallpaper updates live, no Settings dialog round-trip.
• Multi-monitor split: cut the image vertically in half and apply the two halves to two screens at once. Optional yellow split-guide overlay on the canvas.
• Toast notifications confirm save / apply success or failure.
• See building-wallpapers.md for the workflow.
• POST /screen/<N>/background bridge endpoint accepts a PNG body, writes it to %LOCALAPPDATA%\SignalRGBWallpaper\screens\screen-<N>-<millis>.png, updates the screen's config to point at it, persists config.json, and pushes the new settings to connected wallpapers. Unique-timestamp filename avoids browser-cache hits on rapid re-uploads; older screen-<N>-*.png files are auto-cleaned.
• GET /builder route serves the bundled builder.html (added via PyInstaller --add-data "builder.html;.").
• "About…" tray menu item opens a dialog with version, repo link, MIT license link, and full open-source attribution: Python (PSF), pystray (LGPL 3.0), Pillow (MIT-CMU/HPND), PyInstaller (GPL 2.0+ with linking exception), tkinter (PSF), plus reference notes for Lively Wallpaper (GPL 3.0) and SignalRGB (proprietary, via plugin API).
• Docs: docs/building-wallpapers.md now leads with the built-in builder as the quick path and reframes the GIMP workflow as the full-control alternative. docs/tray-settings.md documents the new "Build Wallpaper…" menu item.

Changed

• Build command in docs/building-from-source.md: dropped --specpath build_bridge (broke --add-data resolution because PyInstaller resolves data paths relative to the spec file's directory) and added --add-data "builder.html;.". Spec file now lands next to bridge.py; gitignored.
• .markdownlint.json: MD013 now skips code blocks and tables (legitimate long lines in PowerShell snippets shouldn't trigger).

[0.2.3] - 2026-05-17

Fixed

• Lively pause handler in v0.2.2 mishandled the documented payload. The wiki spec is a JSON-encoded string like '{"IsPaused":true}' (note the field name and direction — IsPaused, not IsPlaying or IsRunning). The v0.2.2 handler treated raw strings via a regex that didn't match and defaulted to "playing", so the pause was never applied even when Lively's hook fired. Now we JSON.parse strings first and read IsPaused correctly, with defensive fallbacks for other field shapes some Lively builds use.
• Added a permanently-visible PAUSED badge in the top-right corner of the wallpaper (independent of the "Show debug overlay" toggle) so the pause behavior is verifiable.

Known issue

• Lively's "Pause wallpapers" tray menu is best-effort — whether the JS hook fires depends on the Lively build, its current WallpaperPlaybackPolicy state, and IPC delivery to the player process. On setups where Lively pauses other wallpapers but not ours, the issue is Lively-side (the hook IPC never reaches the WebView2 player); on setups where it doesn't pause anything, Lively's pause behavior is itself broken in that environment. We ship the correct opt-in ("Arguments": "--pause-event true") and a correct handler — if your Lively starts firing the hook, our code will pick it up.

[0.2.2] - 2026-05-17

Fixed

• Wallpaper now respects Lively's "Pause wallpapers" control. The glow layer freezes on its last colours when paused and resumes when playback is re-enabled. Implemented via Lively's livelyWallpaperPlaybackChanged(state) JS hook (payload shape varies across builds — we accept boolean, {IsRunning}, {playing}, {isPlaying} and string variants). Also pauses on document.visibilitychange as a defensive fallback for hosts that hide the page without firing the playback hook.

[0.2.1] - 2026-05-17

Changed

• Tray Settings dialog no longer auto-closes after Save — the window stays open so you can iterate on multiple screens / test live changes without re-opening from the tray each time. A "✓ Saved at HH:MM:SS" indicator next to the button confirms each save. The bottom button is now labeled Close (was "Cancel") to match the new behavior; pressing it just dismisses the dialog (any unsaved edits since the last Save are discarded).

[0.2.0] - 2026-05-17

First public release.

Added

• Multi-screen support (1–3 monitors). The SignalRGB plugin announces one virtual device per screen; each pulls colours from its own canvas region.
• System tray icon (SignalRGBBridge.exe) with a per-screen settings dialog (background image picker, layout, glow strength, dim, blur, bar sliders, debug overlay toggle). Settings are pushed live to running wallpapers over WebSocket — no Lively reload required.
• Bridge-owned screen count: tray combo "Number of screens" controls how many devices SignalRGB exposes. The plugin polls the bridge's GET /config endpoint and removes excess controllers on the fly.
• Pre-baked Lively wallpaper bundles, one per monitor index: each hardcodes a screen-index meta tag so it subscribes to the correct per-screen UDP stream.
• HTTP image proxy at /image?path=… on port 17320 so the wallpaper page can load images from absolute filesystem paths despite Lively's CEF file:// sandbox.
• Standalone SignalRGBBridge.exe (PyInstaller --onefile --noconsole, ~19 MB, bundles pystray + Pillow + tkinter).

Wire format

• UDP datagram layout: [S][R][screen_index u8][width u16 BE][height u16 BE][rgb...]
• WebSocket subscription: ws://127.0.0.1:17320/?screen=N

Known limitations

• Lively's own "Customise wallpaper" panel is intentionally disabled for these wallpapers (no LivelyProperties.json shipped). All settings live in the bridge's tray dialog. See architecture.md for the reasoning.
• Lively non-MSIX (GitHub installer) is supported. Lively Microsoft Store (MSIX) version cannot load .exe-type wallpapers — irrelevant for this project (we use Type 1 / Web wallpapers) but worth flagging.
