MBXHub Changelog

v0.5.3.5 — Cue It Up

live setlist

• SET LIST badge on the dashboard — the immersive Now Playing card lights up a SET LIST chip in the bottom strip whenever the current track's Comment carries a time-coded setlist. Click it to jump to the standalone Now Playing page with the Tracklist tab already focused.
• Tracklist tab on Now Playing — the parsed setlist renders as numbered index · time · title rows with a per-entry seek button. As playback crosses entry boundaries the active row highlights and a muted sub-line under the title shows what's currently playing within the recording.
• Export setlist from Comments as a CUE file — the Tracklist tab carries an Extract to CUE button. One click writes a real .cue sidecar next to the audio file (UTF-8 with BOM, atomic write via tmp → File.Replace → .bak). The album then expands into virtual tracks across browse, search, queue, and the wavescrubber.
• Setlist heuristic — the detector recognises three line shapes: MM:SS Title / HH:MM:SS Title (time-first, optional - / en-dash / em-dash before title), NN - Title - MM:SS, and NN. Title MM:SS. Threshold: ≥3 monotonically increasing entries whose timestamps land inside the file's duration.
• Wavescrubber chapter ticks — vertical ticks at each CUE virtual track's start, on the dashboard and play.html. Renders only when MusicBee plays the underlying file as a single item (the wave canvas covers the full file duration so ticks scale correctly). When a CUE file is present, MusicBee uses it to play virtual tracks with their real per-song timing; the wave it returns is per-virtual, so the ticks (which mark file-absolute positions) fall outside that canvas — expected for that mode.
• Clickable artist & album on Now Playing — the artist and album lines drill through to browse on both the immersive dashboard card and nowplaying.html.
• Right-click on Now Playing title / artist / album — open in browse, copy filename, copy track URL, copy deep link, copy folder path. Works on phones and tablets.
• Now Playing deep link — the copied link opens browse, expands the album, and scrolls the matching track into view with a brief highlight.

extras

• Extras panel on Now Playing — the “Lyrics” panel is now Extras and holds five tabs: Lyrics, Comment, Tracklist, Fan Art, Video. Image files in the album folder render as a thumbnail grid (click for full size); video files (.mp4 / .mkv / .webm / .mov / .m4v / .avi) render as a list with play arrow + size (click opens the browser's native player).
• Videos on Explore — the expanded album view in Explore shows a Videos strip next to Images when the folder contains .mp4 / .mkv / .webm / .mov / .m4v / .avi.

v0.5.3.4 — sort of evolution

for Browse — multi-artist works

• Multiple-artist and role support improvements — Album Artist and per-track Artist are treated independently. Tracks carrying multiple Artist values — whether stored as separate values or as one delimited string (; / , / & / feat / ft / featuring / with / and / vs / presents) — appear under every contributor's drill-down. The filter consults the full role union: Artist, Performer, Guest, Remixer, Composer, Conductor.
• CUE virtual tracks expand — CUE-backed single-file albums now expand to all their virtual tracks on browse drill-down, including under ?album=&people= query shapes that previously deduped to one row. CUE virtual rows also emit albumArtist so multi-artist covers compilations keep every CUE row under the artist's drill-down.
• Roles flag for API consumers — /library/files?roles=true returns every per-track role bucket MB tracks separately (artistsRole, performers, guests, remixers, composers, conductors, artistsUnion). Default off; only paid for when requested.

for Custom Sorts

• Custom sorts — define your own sort orders over any MusicBee tag (Custom1–16, Virtual1–25, year/sort fields) in Settings. They appear in the Albums tab's sort dropdown next to the built-ins. The Tag picker reads MusicBee's friendly tag names when configured.
• Per-track sort-field value on expand — when the Albums tab is sorted by a custom-* sort, expanding an album now shows each track's value of that sort field as a muted inline badge between the artist line and the duration. Sort by AutoQ Moods → expand → each track shows its mood. New ?include=<TagName> on /library/files drives it, accepts any tag from the 48-tag customSorts allowlist.

for Now Playing & Dashboard

• Waveform on the scrubber — peak + RMS overlay drawn behind the played-portion fill, on both the play.html transport bar and the dashboard's progress bar. Backed by MusicBee's per-track NowPlaying_GetSoundGraphEx (served as /nowplaying/sound-graph-ex). Painter lives in a shared transport-wave.js component.
• Immersive Now Playing refresh — centered nowrap+ellipsis metadata chips build bottom-up in the lower frame; mood and format badges anchor the corners and flank the time text in a single strip.
• Progress bar XL preset — new XL size (40px / 56px with waveform) plus a sweep: S almost a hairline (2px), M/L bumped a touch (14px / 24px). Waveform fill opacity scales down with size (0.34 → 0.16) so the silhouette reads through cleanly on the chunky presets.
• Tunable progress bar — new progressBarHeight, progressBarFillOpacity, and progressBarFillColor overrides on top of the preset. Set any one to dial the bar independently of the S/M/L/XL preset; defaults leave preset behavior unchanged.
• Mood badge — channel name only by default — the +0.1 87% vibe-score and confidence stats are now gated behind diagnostics.showMoodDebugStats (off by default). Tuning users flip it on; everyone else gets the cleaner badge.

polish

• Immersive text scale shift — M shrinks to fit at 100% zoom; S, L, XL trimmed proportionally.
• Tunable bar lifts the metadata stack — non-zero progressBarHeight overrides now lift .np-info, time, and mood/format with the actual bar height, not just the preset class.
• Encoding-aware CUE parsing — BOM detection, strict UTF-8, and Windows-1252 fallback now applied on every CUE read.
• Safari backdrop on explore & browse — paired -webkit-backdrop-filter rules so the chrome blur renders on Safari and iOS.
• Artist counts agree across surfaces — cmd-K, drilldown, browse-search, and /library/albums/by-artist all report the same album count (via ArtistPeople); featured-on entries surface from every path.
• CUE album count reconciles after expand — the artist-album badge updates to the expanded track count once virtual tracks land.
• Dashboard up first on startup — renders immediately; library refresh, AlbumIndex pre-warm, and AutoQ mood cache build sequentially in the background.
• Search returns every matched album — /library/search no longer caps the album fan-out; broad substrings now surface every CUE compilation, not the first 50.
• Duplicate CUE entries in playlists — each occurrence of the same CUE album now expands its full virtual-track list; previously only the first did.
• Volume rocker pre-popover — vol up/down on play.html toolbar work before the mixer popover has been opened.
• Immersive waveform layout — no more dead gap above the bar when the waveform paints in immersive.
• Non-Latin sort ordering — album titles in Cyrillic / Greek / CJK / Hebrew / Arabic sort under their own scripts; ASCII unchanged.
• Malformed-numeric sort — explicit Numeric sorts with unparseable values land at the end, not the top.
• CursorLock hold-time diagnostic — warn measures hold only and emits after the lock releases.

v0.5.3.3 — new parmesan

for AutoQ — the Auto-Cal loop

Auto-Cal is a MusicBee playlist you maintain by hand. It holds anchor tracks — songs you've picked as corner / archetype examples for the valence and arousal axes ("this is what I mean by maximum energy," "this is what I mean by deepest sad"). Everything below either feeds into that playlist, reads from it, or measures how well the model still agrees with it.

• Auto-Cal playlist — new vamAnchorPlaylist setting (default "Auto-Cal") names the playlist that holds your anchors. Resolved by name on every request, so renaming in MusicBee takes effect without a restart.
• Annotations — the annotate page serves Auto-Cal tracks first and auto-flags them as anchors on commit. Pre-fill mode lets you rate or correct an existing label instead of starting blank.
• Gates — new panel at the top of the AutoQ Tuning Console. Joins the Auto-Cal playlist with your annotations and shows how well the current model scores them. Anchor in, drift out.
• Pairwise tuning, joined up — the A/B judgements from /pages/tune.html and the anchor labels from the annotate page now feed the same calibrator. One loop: judge, anchor, measure, retrain.
• Mood Data card — the AutoQ console shows track title, artist, and genre next to the mood values, so you know which song produced the numbers while you're tuning.
• More mood signals — AutoQ reads new Essentia features (HPCP entropy and crest, HFC, spectral complexity, chord strength) and weighs them with a trained Ridge/PCA model.
• Trained model toggle — new useTrainedModel setting (default on). When off, AutoQ uses the legacy weighted-sum formula and every slider, intercept, genre bias, and the Calibrate / Suggest buttons in the Estimation Mixer are live. The console shows the active path (model vs formula vs missing) and auto-hides the fallback sliders when they don't apply.
• Model on disk supersedes embedded — drop a fresh mood-model.json into %AppData%\MBXHub and it wins over the copy embedded in the DLL. POST /vam/model/reload picks it up without a restart. Closes the no-rebuild iteration loop on the retraining side.

for Listen Here

• LocalQueue on play.html — Play / Queue Next / Queue Last from the play, browse, and explore iframes drive a browser-side queue in Listen Here mode instead of POSTing to MB. Room stays silent; CUE offsets ride through. Restores v0.5.0.6 behavior lost in the iframe split.
• Rating routes to local track — POST /dashboard/rate/{n} honors ?url=; play.html passes the current Listen Here track. Album view also normalizes 0–100 / POPM star scales from non-MB taggers.

for Discovery

• SSDP banned-peers list — New ListBox under Network in the settings dialog. Listed IPs are dropped silently at the SsdpCore level before MX delay. Persisted in mbxhub.json, admin-only.

for Now Playing

• Lyrics/Comment toggle — when a track has both a lyrics tag and a non-empty Comment tag, the lyrics panel header on nowplaying.html swaps the static “Lyrics” label for a [Lyrics | Comment] segmented control. Click to flip the body between the two. Comment-only tracks keep their “from comment” chip. Gated by LyricsFallback; ApiDisableLyricsFallback suppresses the new field too.
• Always-show Immersive seek bar — new Dashboard setting ImmersiveAlwaysShowProgress keeps the seek bar at full height in Immersive mode instead of fading with the rest of the chrome. Off by default; flip it on under Settings → Dashboard.

for VAM Gates

• Configurable anchor playlist — new AutoQ setting vamAnchorPlaylist (default "Auto-Cal") replaces the hard-coded playlist name in GET /vam/gates/report. Resolved by name on every request, so renaming the playlist in MusicBee takes effect without a restart.

for History

• 1y window — the time-range chips on /pages/history.html add a 1y option after 30d, lifting the previous 30-day ceiling for browsing recent plays.
• Always lands on Today — first load defaults to the Today chip regardless of what was selected last; small / fast query renders the page within a fraction of a second.
• Background warm — the 1y cache starts building in parallel right after the initial Today render. By the time you click 1y the cache is hot, so the longer view is instant. First-page UX no longer waits on the larger query.
• History card on the index page — /pages/ picks up a History tile between Play and Explore.

for Browse

• Single-track album row clicks land — loose-file albums whose MusicBee auto-grouped name doesn't match the file's Album tag returned zero rows from /library/files, so the album-row expand looked dead and Play / Next / Last silently no-op'd. Inline expand and the per-album action buttons now share the same firstTrackUrl fallback the breadcrumb drilldown already had — clicks produce a real track and the buttons play it.
• Album-subheader Play button — the per-album Play affordance in artist drilldown now renders with an explicit inline-flex style and the ▶ glyph used elsewhere, so it can't fall out of the DOM under any combination of upstream CSS.

polish

• Branch suffix on non-release builds — version chip reads v0.5.3.x-<branch> off master / main; tag builds stay clean.
• Media drawer — wider (min(85vw, 480px)), filter input above the list, basename in the tooltip.
• Media category visibility — recursive now, matches the scanner.
• Immersive NP small size — title cluster no longer clips or escapes the panel.

v0.5.3.2 — relentless

drive

• AutoQ mood bands — new Relentless 💀 and Edge 🤘 channels, default channel positions and combo threshold tweaked. Existing user configs auto-migrate the new bands on first load.
• Only show local images — new Media setting blocks online artist-picture sources (last.fm and friends). Off by default. Toggle on to keep /library/artist/{name}/pictures and /nowplaying/*-pictures on disk-only.
• Mixer charm header + mute tighten up at small sizes — the app-launcher header button is now ⅓-width and the mute button is ½-width inside the charm row, across all five charm sizes (S/M/L/XL/XXL). Frees horizontal room for the volume slider on cramped bars.
• play.html A-Z artist scrub bar — iOS-Contacts-style vertical index pinned to the right edge of the artist column. Tap a letter to jump; drag along the bar to live-scrub the artist list with a centered letter overlay. Letters with no matching artist are dimmed. Touch-first surface for tablets where the existing keyboard typeahead doesn’t reach.
• play.html search chip — magnifier button next to the album/artist toggle opens the Cmd+K command palette on tap, so tablets and touch-only sessions get the same federated search surface the keyboard shortcut already provided.
• AutoQ pairwise tuning — new /pages/tune.html shows two tracks A/B with their current AutoQ classification; pick which is more intense or more positive per axis (1/2/3/0 keys, A/B to listen). Judgements accumulate to mbxtune-pairs.json and /autoq/tune/scores returns the Bradley-Terry ranking — raw material for fitting V/A weights against actual user judgement instead of theory.

v0.5.3.1 — bring it on home

come together

• History page — /pages/history.html — recently played tracks with day-range chips and per-row P / L queue buttons. New dashboard footer link, disabled by default; enable via the Dashboard footer-links settings UI.
• Hubs page — /pages/hubs.html — picker of every MBXHub instance this browser has seen on the network, plus a manual host:port box. Fed by GET /system/hub-neighbors (Shell SSDP scan) and local browser memory. New dashboard footer link, disabled by default.
• View transitions — cross-fade between shell pages in Chromium browsers.
• Tray Libraries pre-warm — first open is instant instead of a 3s “Searching…”.
• play.html transport metadata fix — was missing on narrow portrait, duplicated on widescreen + Now Playing. Now mode-driven at every width.
• Listen Here on play.html — output toggle in the transport flyout. Speakers (room / MusicBee, the default) or this device's browser (private audio via /stream/<file>). Play/pause, prev/next, volume, mute, scrubber, and auto-advance all route to the active side. Flipping to browser pauses MB; flipping back resumes. Small 🎧 chip in the transport bar shows the current target. Persisted per-client in localStorage.
• Explore icon cycles album / detail view — same icon on the play.html transport. First click activates explore, subsequent clicks toggle the expanded hero + track-list overlay. Same hook the T / Enter keys have always exposed.
• play.html volume rocker + mute follow mixer default fader — transport + / − and mute on play.html now route through the mixer iframe via postMessage — the same charmCmd protocol the dashboard mixer charm uses. The active default fader (player / device / endpoint) is honored end-to-end. WS VolumeChanged no longer stomps the slider in device / endpoint mode — the iframe is the single source of truth, reporting back via charmVolume / charmMute. Prior bugs the rework displaces: rocker piggy-backed on a /mixer/volume PUT that only handled player + device (not endpoint); mute always hit the player regardless of fader.
• /mixer/volume wires endpoint fader — GET + PUT now resolve the active endpoint (first entry of endpoints[]) and call GetVolumeAsync / SetVolumeAsync directly. Soft-fall-back to Player_GetVolume / Player_SetVolume if no endpoint is configured or the Devialet call fails — the actual fader hit is surfaced in the response so the client knows where the request landed. This completes the slider-drag path for endpoint mode (rocker + mute were already routed via the iframe).
• browse search expanded in iframe — the click-to-expand search icon stays only at phone widths (<700px). At desktop / tablet widths the input is always full-width so you can start typing immediately.

v0.5.3.0 — cmd and search more

• Federated search endpoint — New GET /search?q=&buckets=&limit=&cursor= runs typed buckets in parallel (tracks / albums / artists / playlists / saved / etc.) with cursor pagination on the tracks bucket, facet counts, and a top-hit response. Backs the Cmd+K palette and any client wanting a single call instead of fanning out. ?dsl=true opt-in routes the query through the new DSL parser.
• Search DSL — Qualifier syntax (artist:, album:, genre:, year:, rating:, fmt:, range / boolean / grouping operators) on top of the existing strict / substring modes. Opt-in per call via ?dsl=true on /library/search and /search; cheat sheet at GET /library/search/syntax. Default off so existing free-text callers are unaffected.
• Saved searches (CRUD + scheduled evaluation) — Persist a query under a name and have the server re-run it on a schedule. GET|POST /search/saved, GET|PUT|DELETE /search/saved/{id}, GET /search/saved/{id}/results, POST /search/saved/{id}/run. Backed by mbxhub-search.json next to mbxhub.json. Background SavedSearchScheduler ticks per-saved-search interval, evaluates, diffs against last-match URLs, and broadcasts a new SearchMatched WebSocket event when matches change. Enabled by default; toggle via library.search.savedSearch.enabled. Write/mutation routes honor ApiReadOnlyMode.
• Search history — GET /search/history?limit=N, POST /search/history (append; empty body clears), DELETE /search/history. Server-side recents log shared by Cmd+K and any other search bar; falls through to client localStorage if the endpoint is missing or 404s. Mutations gated on ApiReadOnlyMode.
• Search-engine state surface — GET /system/search-index reports the live engine (currently mb) and its index state. FTS5 substrate dropped during the post-decouple harvest; the seam is preserved so a future engine can plug in without touching the call sites.
• Cmd+K command palette on play.html — The keyboard-driven palette that’s lived on the dashboard now drops into play.html too. Shared cmdk-bootstrap.js loader, same actions (Play/Pause/Skip/Volume, Open Charms / Settings / Mixer / Player / Browse / Explore / ARiA, Start AutoQ radio), same federated search, same recents. Press Ctrl+K from anywhere on play.html.
• Cmd+K palette shows global keyboard shortcuts — Action rows now display the global hotkey alongside (e.g. Play / Pause → Space, Skip → →, Previous → ←, Volume up/down → ↑/↓). The cmdk doesn’t bind these — the host pages already do — the palette is just a discoverable cheat sheet.
• Track comment as lyrics fallback — When /nowplaying/lyrics has nothing real to return, MBXHub now surfaces the track’s Comment tag in the lyrics panel with a small “from comment” chip above it. Concert setlists, venue notes, and album liner notes show up where lyrics would on nowplaying.html (and therefore on play.html, which embeds it). Configurable via the LyricsFallback settings section (Enabled, MaxDisplayChars, Label); hard-killable via ApiDisableLyricsFallback.
• Installable web app (PWA) — MBXHub ships a Web App Manifest (/manifest.webmanifest) at root scope so every host page (dashboard, play.html, explore, browse, …) is installable to the home screen / desktop. PWA icon set at /icons/{name} — icon-192.png, icon-512.png, maskable variants, plus the 180px Apple touch icon — generated as MBXHub. Manifest name picks up the host’s display name dynamically (__HOST_NAME__ substitution); start_url is / so launching the icon opens straight to the dashboard.

v0.5.2.9 — Play On

play more more play

• play.html artist typeahead — Type a single letter into the artist column to jump to the first match (1.2s pulse-highlight); type two or more to filter the list down to substring matches. Esc, Backspace-to-empty, or selecting an artist clears. Filter mode is sticky — no idle-clear — so you can read the matches at your own pace.
• play.html parity with player.html — Reactions row in the AutoQ cluster (fire / heart / like / dislike / ban → /autoq/react), “+ Add To Playlist” dropdown beside love and stars (last-used playlist bubbles to the top with a star marker), ARiA presets dropdown in the overflow flyout (auto-hides if ARiA isn't enabled), influence thumbs (artist + genre) on the right-column now-playing card, global media-key shortcuts (Space = play/pause, ← = prev, → = next), and a 30s position-poll safety net behind the WebSocket. Player.html's add-to-playlist + reactions + ARiA + influences are now fully mirrored on play.html.
• Browser logs go to mbxhub.log — play.html now batches console.warn/error sites through POST /system/client-log on a 2-second flush (and sendBeacon on pagehide). Same model dashboard already uses; users running Release builds with no devtools open finally see browser-side errors in the file log.
• play.html overflow flyout auto-closes after firing an action — Tablet/phone overflow popover used to linger after clicking a button inside it; now dismisses next-tick except when the click hits a sub-popover trigger (Add To, ARiA), which keep the parent alive while their menus are open.
• play.html artist drawer is sticky in tablet-landscape — In 700-1023 landscape, the slide-over drawer no longer dismisses on click-outside — you can poke around the middle pane without losing your place. Escape, the drawer-toggle button, and picking an artist are the explicit close paths. Phone / portrait-tablet keeps the original click-outside dismiss because the drawer covers most of the viewport there.
• Play charm — New first-class “Play” charm with an outline-triangle icon that opens /pages/play.html as a webapp surface, mirroring the existing Player / Explore / Browse charm convention.
• Dashboard no longer steals focus on track change — updateTrack now uses the soft inline-refresh path instead of a full location.reload(). The reload was raising the dashboard tab to foreground on Firefox (and some Chrome configs) every time MusicBee changed tracks, even when the user was reading in another window. Soft path covers the same content delta — rating, love, duration, progress, influence buttons, artwork — without the focus side-effect.
• Shell tray menu — Machines submenu renamed to Libraries; each enumerated peer now offers Show QR code and Show diagnostics alongside Open dashboard / Set as SMTC target, opening /system/qr and /diag on that specific host.

v0.5.2.8 — Technologic

Harder, Better, Faster, Stronger

• SMTC Bridge target switching — Tray menu lists the local MBXHub plus discovered network peers; click to retarget the SMTC bridge to any of them. Useful when you want the Windows media flyout / lock screen / Bluetooth controls to mirror a different machine's playback.
• Headless tray toggle — tray.disableTrayIcon: true in mbxhub-shell.json runs the Shell with no tray icon. SMTC bridge still publishes; just no UI.
• Aspect-ratio sizing — Panel and artwork scale together via CSS aspect-ratio. Pick a ratio, get that ratio.
• New settings for dashboard nowplaying column width, height, and gutter — ColumnMaxWidth, ColumnGutter, and ImmersiveMaxHeight in mbxhub.json. ImmersiveMaxHeight default bumped 400 → 600.
• ImmersiveArtFit setting — Pick contain (default; whole album art with blurred-background letterbox) or cover (cropped to fill panel edge-to-edge, no bars).

v0.5.2.7 — Nothing Else Matters

Keeping what matters, removing what doesn’t

• Mood scanning removed from MBXHub — Cut all integrated mood scanning, federation, fleet aggregation, peer-sync, and MetaServer from MBXHub. AutoQ stays first-class, reading a static mbxmoods.json populated offline by truedat.
• MetaServer endpoints removed — All /meta/* endpoints removed from the REST surface.

v0.5.2.6 — in progress

A Plethora of Settings and More

• Installation profiles — Standalone / Island / Fleet dial drives MetaServer, peer-sync, SSDP, warm-up, fallback, remote-bind. Standalone is the new default. GET/PUT /system/endpoint-type.
• MBXHub.exe tray + auto-launch MusicBee — UI-mode dispatcher (GUI/tray on no-args, CMD on subcommand, -cli attached). Tray: Open MusicBee, Status, Reconnect, Settings, Start with Windows, Quit. Click from Start menu launches MusicBee.
• Settings — A lot of new and rearranged controls land in both the plugin’s Settings window and the browser settings page. Most changes apply live without restarting MusicBee. Profile-driven defaults make a fresh install behave sensibly out of the box.
• API Access — Fleet-routing edits have their own permission now, separate from shuffle controls. New master switch on the Shell to block remote writes to its endpoints.
• Settings UX — Settings form rearranged for clarity. Bandwidth toggles grouped together. AutoQ has a single master on/off that gates the related settings. Tabs run horizontally instead of vertically. The Start Shell button got a clearer label, and the SMTC toggle moved to the API Access tab where it logically belongs.
• NP panel cap — ImmersiveMaxHeight now honored across zoom variants and the desktop ≥1024 px @media block (was previously stomped by hardcoded ceilings).
• Diagnostics & Performance — New /diag page with live charts of CPU, memory, threads, and GC for spotting performance issues. Detailed log lines at the most-important decision moments make future spikes easy to trace.
• Configurable transport button — The extra button in the dashboard transport row (used to be hardcoded to Explore) can now be set to open a charm or a page of your choice. Configured in Settings.

v0.5.2.5 — Worker Bee

Beekeeper’s Daughter

• play.html — new player page — Device-adaptive 1/2/3-column view for phone, tablet, and desktop browsers. Incorporates explore, browse, and now-playing surfaces, shaped after the MusicBee 3 default skin. Adapts to device and theme settings.
• Dashboard theme color picker redesign — Native browser color pickers, curated preset swatches, and an intensity (saturation) slider. Reaches pure black, pure white, and true neutral grays; background, surface, text, and accent each get independent hue/saturation/lightness.

v0.5.2.4 — Moodserver

Dynamic Range Computation

• Dynamic Range as a mood feature — Essentia LRA (BS.1770 Loudness Range in LU) now travels alongside BPM/Loudness/etc. into the AutoQ mixer. Arousal weight slider defaults to 0.05. Fallback chain for legacy entries: derive from Loudness/RMS, then genre-default (classical 17, jazz 13, rock 10, metal 6, hip-hop 5), then constant 8.

Distributed Scanning

• Scanner Pool with auto-discovered workers — Master Shell's ScannerPool in scan.mode = "auto" builds a round-robin pool from local + every SSDP-discovered peer that advertises the scanner capability (i.e. has truedat.exe installed). Plugin's ScanEnqueue WebSocket events get dispatched across the pool: local scans run in-process, remote dispatches POST /meta/scan with the file's UNC share path so the worker can read it over the network. Failed nodes are marked unhealthy after 3 consecutive failures and probed every 60 s.
• UNC share path resolution — Two new settings, SyncLibraryPath (e.g. D:\Music) and SyncSharePath (e.g. \\masterpc\music), let the master compute UNC paths for files when dispatching scans to remote workers. Workers receive the share form, pass it to truedat as the file path, and read the audio over SMB. Without these set, remote dispatch falls back to the local path (only useful if all nodes share a drive letter).
• POST /meta/scan on Shell — New endpoint accepts {file, share, priority} and enqueues into the local ScanWorker. Responds 200 {status: "queued", file} immediately; truedat runs and ingests asynchronously. 503 SCANNER_UNAVAILABLE when the node has no truedat installed.
• Merge-on-ingest federation — MetaService.IngestAsync used to be first-write-wins: any existing row with non-zero base fields caused the entire incoming observation to be dropped. That meant a peer rescanning with a richer feature set couldn't fill in missing fields. New three-tier strategy: new row → full write; all-zero garbage → full overwrite (recovery); existing with data → merge (base scalars stay first-write-wins to avoid stomping good data, nullable extended fields fill from null, DR upgrades when incoming source rank is strictly higher: essentia-lra > derived-peak-rms > fallback-genre > fallback-none). Federation now actually converges across heterogeneous peer versions.

39 Extended Essentia Features

• Full Essentia output now persisted — truedat used to extract ~15 scalars from Essentia's streaming-extractor-music output and discard the rest. 39 additional scalar features now plumbed end-to-end: loudness dynamics (momentary, short-term, replay-gain), silence profile (20/30/60dB), spectral shape (rolloff, complexity, entropy, kurtosis, skewness, spread, strong-peak, decrease, energy + 4 energy bands), HFC, full Bark/Erb/Mel band stats (crest, flatness, kurtosis, skewness, spread × 3 families), beats-loudness, chords-strength, HPCP crest & entropy. All nullable so legacy rows read as null, never 0. autoq.html Track Mood Data renders all 54 feature rows with — for fields the track lacks.
• truedat re-extract gate — Cache-reuse paths in truedat now check !DynamicRange.HasValue; tracks from old truedat builds (no LRA) automatically fall through to a fresh Essentia pass on next run, picking up all 39 new fields in the same analysis. Cache copy preserves the full feature set across reruns once captured.

Fleet Dashboard

• GET /system/fleet aggregator — Single endpoint on master plugin fans out to local Shell + every knownPeers entry in /meta/sync/status, fetches each node's /meta/health and /meta/stats in parallel (3 s per-node timeout), returns aggregated queue depth, scan status, sync state, DB size. Per-node status field flags up | down | timeout so partial outages don't fail the whole call.
• Fleet panel in autoq.html — New table under MetaServer section polls /system/fleet every 5 s while the page is visible. Per-row: name, status dot, tracks, queue depth (highlighted in accent when >0), scan status, last-sync rel-time, last-sync result, DB size. Headline meta line shows N/M nodes up · X tracks · Y queued · updated Zs ago. Pauses on tab hide; manual refresh button.
• Per-node worker visibility — Fleet table now surfaces the scan worker's live state per node.

Explore Enhancements

• Discography navigation inside “More Info” — Clicking an album in the related-albums grid of the expanded album view now updates the view in place instead of collapsing it and dropping you back to the top-level stack. Hero, track list, metadata, and image strip re-render for the newly-selected album; the grid’s active marker moves along.
• Arrow-key navigation of the discography grid — Left / Right arrows while the expanded view is open step through the discography grid, scrolling the target card into view and populating the expanded panel with the new album. Works the same way for both solo-artist and compilation contexts (which surface same-title-different-artist rows).

v0.5.2.3 — XL Charms

Whole Lotta Love

• Charm Bar: XL & XXL Sizes — Charm and transport button sizes now cycle S / M / L / XL / XXL (XL = 64px, XXL = 76px). The previous “Large” (52px) was too small for comfortable touch on small high-density panels — XXL lands at ~0.6″ physical, right in the sweet spot.
• Per-Charm Size Overrides — New charmBar.sizeOverrides dictionary (charm ID → S/M/L/XL/XXL) lets individual charms break from the bar-level size. A single charm class-name override wins via CSS specificity, so you can keep the bar compact while boosting one specific charm.
• Charm Row Breaks — New charmBar.breakBefore list of charm IDs forces a row break before any named charm. Combined with Per-Charm Size Overrides, the volume mixer can sit on its own row with XL buttons while the rest of the charms stay at M — one-handed tablet use gets easier without blowing up every button.
• NP Text Size Applies to All Styles — The dashboardLayout.immersiveTextSize setting (S / M / L / XL) now governs metadata text size for every now-playing style, not just immersive. Classes renamed internally from immersive-text-* to np-text-*; the setting name is unchanged for backward compatibility.
• ARiA Action-Menu Charm — ARiA moved out of the toggles row into its own built-in charm (aria.json). New display: "action-menu" charm mode: single trigger + popover of preset actions. Keyboard-navigable (Arrow nav, Enter activates, Tab/Esc closes), auto-orients above or below the trigger based on viewport position. Presets continue to come from AriaPresets in mbxhub.json; the charm's expand is populated at load time. Respects all charm-bar settings (order, hidden, size, sizeOverrides, breakBefore).
• Adjacent-Token Search (default on) — Multi-word library searches now require the query tokens to match consecutive word prefixes in a single field (title, artist, album, or genre). “St Anger” matches the album St. Anger but no longer pulls in a track whose title contains “Anger” while its album contains “Story.” Single-word queries are unaffected and still use the strict prefix + concat fallback (so “acdc” still finds AC/DC).
• New Setting: library.disableCrossFieldMatching — Toggles the new adjacency rule. Defaults to true (adjacency required, the new default). Set to false to restore the previous cross-field behavior where tokens could match anywhere across any of the four fields. Ignored when substring search is enabled. Exposed as a checkbox in Settings (Configuration → Library) and picked up by the dashboard settings page; browse.html honors it live from /system/settings.
• Artwork Sizing Fix (zoom@67 + horizontal) — Fixed CSS.
• Explore: Queue-Next Button on Expanded Tracks — Expanded album track rows now show a “Next” button alongside the existing queue-last +, rendered as a hover overlay.
• player.html 3-Column Transport Fix — Transport, progress, stars, and reactions were squeezed into the artwork-flanked .meta column on FHD 3-col layouts. Controls are now lifted out to span the full .player width, and they stay visible when the NP card is collapsed.
• Split NP Layout Fix — .np-style-split rows now include min-width: 0 so square art no longer letterboxes inside a tall column when the metadata panel shrinks.
• Footer: Settings Entry — /pages/settings.html added to the default dashboardFooterLinks list (disabled by default). Tick it in the plugin Settings dialog to surface it in the dashboard footer.

v0.5.2.2 — Search Party

I Still Haven’t Found What I’m Looking For

• Library Search Word Boundaries — Fixed a regression where library search matched query words as loose substrings, so “St Anger” pulled in every album containing “Stranger.” Server search and browse.html inline/tab-badge filters now match each query word as a prefix of a real word in title/artist/album/genre.
• Album Artist Toggle in Search Results — Fixed: the Album Artist / Artist toggle on the Library Browser Artists tab is now honored when results come from a full-text search.
• New Setting: library.disableSubstringSearch — Controls library search matching globally. Defaults to true (strict word-boundary, the new behavior). Set to false to restore loose substring matching library-wide. Exposed as a checkbox in the plugin Settings dialog (Configuration → Library) and picked up automatically by the dashboard settings page.
• Per-Call Search Override — GET /library/search accepts a new ?substring=true|false query parameter that overrides the setting for a single call. The response now includes a mode field ("strict" or "substring") echoing which path was taken so clients can verify.

v0.5.2.1 — Men at Work

Refinements

• Immersive NP: Blur Fill — Immersive now-playing mode shows the full album artwork (no cropping) with a blurred, saturated version of the same image filling any letterbox gaps. Works with all aspect ratios — square, portrait, and landscape art all display correctly.
• Observability — Timing instrumentation on hot code paths. REST requests over 200ms auto-promote to Info level. Client-side search render and track-change timing in browser console.
• ES5 Compatibility — Fixed search on older browsers that don’t support ES2020 optional chaining syntax.
• MusicBee API v58 — REST and RPC endpoints for expression evaluation (/library/evaluate), placeholder artwork (/library/no-artwork), and peak/RMS metering (/nowplaying/peak). Returns 501 on older MusicBee builds.
• Volume Gesture Setting — New dashboardLayout.disableVolumeGesture setting. Vertical swipe on artwork for volume control is now off by default to avoid conflicts with page scroll. Track skip gestures (horizontal swipe) unaffected.
• Pinch Zoom — theme.disablePinchZoomLock unlocks native pinch-to-zoom on mobile. Also available as a toggle in the theme drawer.

v0.5.2.0 — Version Upgrade

MusicBee API v58 Support

• MusicBee API v58 — Updated plugin interface to API revision 58. Adds delegate definitions for MB_Evaluate, Library_GetNoArtworkUrl, and NowPlaying_GetPeak. Gracefully absent on older builds.
• Browse: Tracks Tab — New search-driven Tracks tab in the library browser. Type to search tracks via /library/search with debounced server queries and AbortController cancellation. Full track UI with play, queue next/last, listen-here, and playlist buttons.
• Browse: Video Play/Queue — Video items in both the Videos tab and search results now have play, queue next, and queue last buttons. Previously videos rendered as name-only list items with no actions.

v0.5.1.9 — Dashboard Layout Level-Up

Dashboard Now Playing Display Modes Options

• Split NP Style — Two-column grid: album art left, metadata right. Configurable column ratio (40–70%) via mbxh_split_ratio localStorage key.
• Immersive NP Style — Full-bleed album art with gradient-scrim metadata overlay. Progressive reveal: chrome fades in on hover/touch, fades out after configurable delay (1–10s via mbxh_immersive_fade).
• Compact NP Style — Tighter padding, smaller artwork and text for dense dashboards.
• NP Style Picker — Header button cycles through all 6 styles (Full, Compact, Horizontal, No Art, Split, Immersive). Per-device preference stored in localStorage.
• Charm Button Sizes — Configurable charm button size via charmBar.buttonSize setting: S (32px), M (40px, default), L (52px).
• Progress Bar Thickness — Configurable via dashboardLayout.progressBarSize: S (4px), M (6px, default), L (10px).
• Startup Diagnostics — Log now captures version+build epoch, Windows version, plugin path, settings path, port/remote/autoQ config, .NET runtime, and mood source (MetaServer or local file) on every startup.
• Settings Page — Dashboard layout now rendered as interactive checkbox list with reorder arrows (was two separate text fields for order and hidden).
• Dashboard Search — New search section — full library search from the dashboard. Fuzzy album matching (client-side, instant) + server-side track search with AbortController. Filter tabs (All/Albums/Tracks), inline action card (play, queue next, queue last, explore), keyboard navigation (/ to activate, arrows, Enter=play, Shift+Enter=queue), search history in localStorage. Configurable bar size via searchBarSize.

v0.5.1.8 — Crate Full of Albums

Albums Artwork Explorer

• Media Endpoint — /media/* — browse and serve images and videos from configured folders. Rotation, categories, seeking. Disable via disableMedia.
• Projector Charm — slideshow and video player at /pages/media. Image crossfade, video transport controls, folder browser, configurable timer. Hidden by default.
• Explore Page (v3) — /pages/explore.html — art-first album browser. Full-bleed artwork fills the viewport. Progressive reveal chrome fades in on interaction, fades out after 5 seconds. Gallery mode with crossfade transitions, fan art integration, and artist photo gallery. Edge gestures: top touch opens search, swipe up opens tracklist, tap enters gallery, double-tap plays. Transport controls (play/pause, skip, volume wheel). Source filters (All, 1mo, 3mo, 12mo, Unheard), diacritic-normalized search, enhanced album filter, PDF booklet viewing. Hidden by default in charm bar.
• Album Discovery Endpoints — GET /library/albums/unheard (albums where all tracks have playCount=0), GET /library/albums/with-pdf (albums containing PDF booklets). Both support ?offset=&limit=.
• Artwork & PDF Endpoints — GET /library/file/{url}/artwork-count probes embedded artwork images (up to 20, cached). GET /library/file/{url}/pdf serves PDF booklets from album folders. GET /library/file/{url}/has-pdf checks existence.
• Fan Art API — Two new endpoints for browsing folder images alongside album art. GET /library/file/{url}/fan-art lists all images in an album's folder (Discogs scans, booklet pages, promo photos). GET /library/fan-art/{path} serves them. Excludes thumbnail artifacts and WMP cache files. Results cached per-session.

v0.5.1.7 — Remote Control Made Easy

SMTC anywhere, scanner delegation, and multi-machine polish

• SMTC Link Charm — Dashboard charm discovers MBXHub endpoints on the network and lets you switch which one the Shell’s SMTC bridges to. Tap to re-target your Windows media controls at any machine. Preferred address list with SSDP fallback replaces manual host/port config.
• Playlist Enumeration Fix — GET /playlists was truncated. All playlists now returned correctly.
• Mixer: Network Speaker Section — network speaker scan/connect controls collapsed into an expandable section at the bottom. Local faders stay top-level.
• Preferred Remote Scanner — set scan.remoteUrl in mbxhub-shell.json to forward scan requests to a dedicated scanner via POST /meta/scan. Host disables local scanning (scan.enabled: false), remote does the work. Results flow back via PeerSync.
• Scan Configuration UI — Local scanning toggle in autoq.html MetaServer section and SettingsForm. Discovered remote scanners listed with status. Shell config managed via GET/PUT /meta/config endpoints.

v0.5.1.6 — Mood Data Everywhere

How I learned to stop worrying and reuse the original scan

• MetaServer — REST API in MBXHub.exe (Shell) for mood and fingerprint data backed by MBXU SQLite. Replaces the mbxmoods.json flat file. Import existing data via POST /meta/import, query features via GET /meta/features, ingest new scan results via POST /meta/ingest. Runs on port metaPort (default: REST port + 1).
• Distributed Scanning — any machine with truedat can scan local files and POST results to the central MetaServer. Identity matching (hash → audioMd5 → metadataKey) resolves tracks across machines. truedat --meta-server <url> for batch scanning.
• Scan Distribution — scan requests now broadcast ScanEnqueue WebSocket events. The Shell's ScanWorker picks up work and posts results to MetaServer.
• Plugin Dual-Mode — MoodEstimator queries MetaServer on cache miss, falls back to mbxmoods.json when MetaServer is unavailable. Background cache fill, periodic health re-check.
• MetaServer Peer Sync — MetaServer instances discover each other via SSDP and exchange mood/feature data automatically. Pull-based with delta exports (GET /meta/export?since=), zero-config via SSDP discovery. Trigger manually with POST /meta/sync, check status with GET /meta/sync/status.
• Remote Scanning — host broadcasts UNC share paths in ScanEnqueue WebSocket events. Remote Shell instances (scanners) open files via UNC share, run Essentia analysis, and deliver features back via PeerSync. Scanner requires zero path configuration — host owns the mapping. Configure syncLibraryPath and syncSharePath in mbxhub.json.

v0.5.1.5 — Mobile Gestures

Touch-friendly controls and gesture navigation for mobile dashboard experience

• Mobile Gestures — touch gesture controls wherever now-playing artwork is shown. Swipe artwork left/right for next/previous track, up/down for volume ±10%. In the Now Playing charm stacked layout, container swipe left/right switches panels (Now Playing → Queue → Lyrics).
• /mixer/volume Endpoint — GET/PUT routes to the active default fader (player or device). All gesture volume controls use this single endpoint.
• Library Stats — artist count uses /library/artists (was album-artists). /library/albums supports ?albumArtist= filter.

v0.5.1.4 — Player Browse More

Consolidated browse with player for consistent experience and code simplification

• Player Browse — the library browser is now used with the player for a consistent experience and code simplification. Theme and color choices sync across both views.
• Auto Mood Scan — unanalyzed tracks are automatically queued for Essentia analysis when played. Shell hosts background worker, results hot-load into mood cache. Self-disabling if Truedat not found.
• Scan Status — GET /scan/status reports mood cache stats (total, Essentia, fallback counts).
• Browse Art Sizing — resizable album art thumbnails in the library browser via slider control. Size persisted across sessions.
• Unified Theme System — two-slot HSL color model persisted to mbxhub.json. One theme config drives dashboard, player, browse, now playing, and mixer. GET/PUT /system/theme REST endpoints with partial update support. ThemeChanged WebSocket event for live sync across all pages.
• Browse & Search Improvements — album tab filter now matches artist name, not just album name. Artist drilldown returns broader results.
• AutoQ Track Info — GET /autoq/track-mood now includes file URL and album fields for scan integration.
• Status Page — live dashboard with library stats, AutoQ state, mood cache, and feature flags. Correct album count (groups by album artist), mood cache display fixed.
• On-Demand Mood Scanning — POST /scan/track enqueues a single track or full album for Essentia analysis. AutoQ tuning console shows Scan Track and Scan Album buttons when the current track uses fallback estimation. No autoScan setting required.
• Truedat Discovery — Shell automatically finds truedat.exe in the MusicBee Library folder. Fixed ScanEnqueue priority deserialization.

v0.5.1.3 — Improvements

Fun and frustration-free

• Audio Output Enumeration — new GET /devices/audio/outputs endpoint lists all active Windows audio render devices via Core Audio (name, id, isDefault).
• Dashboard Charm Persistence — player actions no longer reset inline charm windows. Browse scroll position, drilldown state, and search are preserved across play, next, rate, love, and all other dashboard controls. Resizable inline browse window with height persisted across sessions.
• Remote SMTC — use the Windows Media control panel to remotely control a MusicBee instance on another machine. Run MBXHub.exe --install on the remote machine, then edit mbxhub-shell.json to point at the MusicBee host. Media keys, play/pause, skip, and artwork all work across the network.

v0.5.1.2 — Mixer

Multi-fader volume control and network audio

• Default Fader — configurable default fader for quick-access controls — dashboard volume slider and keyboard shortcuts target the selected fader.
• Windows Audio Device Volume — control the system audio output device volume directly from MBXHub.
• Network Speaker Integration — Devialet Phantom support with volume control and endpoint management via REST API.
• Endpoint Source Selection — switch audio input sources on network endpoints from the Mixer charm.
• Auto-Discovery — mDNS-based discovery of network audio endpoints on the local network.

v0.5.1.0 — Taste & Discovery

Explore your library through the lens of your listening

• Taste Explorer API — GET /autoq/taste-explorer discovers tracks adjacent to the current taste profile, grouped by genre/artist/mood. GET /autoq/similar finds tracks similar to a seed track. TasteChanged WebSocket event broadcasts profile updates.
• DJ Taste Tab — new “Taste” search tab in the DJ page showing taste-model-driven suggestions grouped by genre, artist, or mood. Similar (~) button on every track for seed-based drill-down. Vibe Filter toggle re-ranks search results by the current taste profile.
• Dashboard Connection Indicator — header shows server name with connection dot inline after the MBXHub logo. Green when WebSocket connected, dims when disconnected. Server name from discovery settings.
• Mixer Charm — expandable charm for remote audio output device switching. Lists MusicBee output devices, switch with a tap. Inline volume controls (shift-click for fine ±1). Standalone page at /pages/mixer.html.
• Library Browser: Album Artist & Collapsible Albums — Artists tab toggles between Artist and Album Artist mode (defaults to Album Artist). Artist drilldown shows collapsible album rows with artwork, year, and track count — expand to reveal tracks. Sort drilldown albums A-Z (honoring Sort-As overrides), Newest First, or Oldest First. Search results group albums as collapsible rows. New endpoints: GET /library/album-artists, GET /library/albums/by-artist. New ?albumArtist= filter and year-asc sort on /library/files.
• Library Browser: Album Grid Enhancements — Album cards show year and track count in subtitle. Play/queue buttons (Now, Next, Last) overlay on album artwork on hover. Sort albums from the header: A–Z, Recently Added (date added to library), Newest (release year), Oldest (release year), or Random Shuffle. /library/albums/detailed now returns year and dateAdded per album.

v0.5.0.9 — Under the Hood

Faster everywhere, no trade-offs

• Playlist Folder Grouping — playlists in the player browse panel and search results are grouped by folder
  • Root playlists listed first, then sorted folder groups with uppercase headers
  • Items show leaf name only (folder prefix shown in group header)
  • Matches dashboard playlist picker ordering
  • Filtering hides empty groups
• Track Metadata Cache — ConcurrentDictionary with TTL eviction, invalidated on track change events. Queue listings with 100+ tracks hit cache instead of 1500 API calls
• WebSocket Serialize-Once Broadcast — events serialized to bytes once and sent to all clients, not per-client
• Router Fast Path — kiosk/party mode checks skipped when disabled, regex routes matched in single pass instead of two
• Scoring Engine — diversity penalty pre-computed maps (O(1) per candidate), single-pass filter chain, TTL-based metadata eviction, ThreadLocal RNG
• Startup & Lifecycle — lazy handler initialization, lock-free rate limiter cleanup, immutable WebSocket subscriptions, bounded log queue (10K cap)
• Dashboard Degraded Browser Support — comprehensive var()/clamp() fallbacks, :focus-visible fallback, emoji detection with text substitution, ES5-compatible JS, form-based volume controls for no-JS mode
• Live Settings Page (settings.html) — Firefox about:config-style editor for dashboard, AutoQ, and shuffle settings with search, category filters, and inline editing

v0.5.0.7 — AutoQ Tuning

Smarter moods, transparent confidence

• Genre-Aware Weight Adjustment - Per-genre multipliers adapt mood estimation to each genre’s acoustic norms
  • 8 built-in genre profiles: Electronic, Metal, Jazz, Classical, Hip-Hop, Folk, R&B, Pop/Rock (reference)
  • 14 multipliers per profile (8 arousal, 6 valence) — weights are scaled then renormalized so total stays constant
  • BPM downweighted for EDM (uniformly high), chord changes upweighted for jazz, brightness boosted for metal
  • Genre matching: exact tag match first, then first-word fallback (e.g. “Progressive Rock” → Rock)
  • Custom profiles via autoQ.genreProfiles in mbxhub.json — override or extend built-in profiles
  • Toggle: useGenreAdjustment (on by default), controllable from Tuning Console
• Confidence Scoring - Every mood estimate now carries a confidence score (0–1)
  • Formula: confidence = sourceBase × channelProximity
  • Source bases: Essentia (0.9), fallback+genre (0.45), fallback-only (0.2) — all tunable
  • Channel proximity: how close the V/A point lands to its nearest mood channel (1.0 = dead center)
  • Color-coded badges on Dashboard, Player, and Tuning Console (green/yellow/red)
  • Confidence gate: mood tags only written when confidence ≥ confidenceMinForTag (0.3)
  • REST API: confidence, confidenceLabel, genreProfile in GET /autoq/track-mood
• Mood Combo Labels - Multi-channel mood descriptions
  • Tracks near channel boundaries get composite labels (e.g. “Upbeat + Energetic”)
