• EV4: Preferred Persistent Speaker (PPS) — choose your default Cast speaker in MBXCast and enable Automatic connection. Press Play to connect, or enable Keep awake to connect when MusicBee starts. Pause, stop and an empty queue keep the established connection in place.
• EV4: Wake device when starting a Cast — optionally wake your preferred speaker when playback starts, if it supports Wake-on-LAN.
• EV4: Keep awake — wake/connect to your preferred speaker without pressing Play and maintain the connection while MusicBee runs. If connection takes longer than 90 seconds, playback stops on Cast and automatic retries pause until you connect the preferred speaker manually; the next MusicBee session uses your saved settings again.
• EV4: Pop out Cast Control into a desktop overlay or a separate browser window.
• EV4: Control Cast volume and mute directly from MusicBee.
• EV4: HUD (app) and Overlay (Hub web) settings refined.
• EV4: DICE — plays a random album, on the AutoQ panel in MusicBee and the radio toolbar on Play, Stations and ON-AIR.
• EV4: Refresh Station targeting by this track or from the queue ahead.
• EV4: Music map: a ring around any track becomes a station — set its size, press Seed, and it starts.
• EV4: HUD metadata settings in HUD Settings to control how it is displayed.
• EV4: Configure which Charms are shown in the HUD.
• EV4: The HUD bonus transport defaults to Explore on new installs.
• MBXCast — casting from inside MusicBee. A MusicBee plugin that drives the cast engine from the player, and makes casting just another audio endpoint: pick a Cast speaker like any other output, your queue stays MusicBee’s queue, and you switch speakers on the fly without re-routing your audio. The HUD, Play page, dashboard and Cast charm still drive the same cast.
• Music Map — your library drawn by mood. Every scanned song is a dot colored by its genre. Filter by artist or album, click a dot to Play now or Play next, and watch the radio’s trail and where it is heading. The Song / Library toggle on the ON-AIR Mood Map, or the new Music Map charm in the overlay or a browser.
• Stations remember the mood. Every way of saving a station now keeps the same settings — flow, genre-free, Tight/Loose, freshness, duration and mood — and playing it puts them back. So a program of two stations can shift the mood, say Upbeat into Night.
• AutoQ radio doesn’t repeat a song in a session. An mp3 and a FLAC copy of the same song count as one. Recently played songs also stay pushed back for hours instead of minutes.
• Library track count fixed — it was coming up short when CUE files were in the library.
• Casting overhaul (beta). Cast MusicBee’s queue to a Google Cast speaker — the speaker fetches each track itself and plays the queue unattended, MusicBee’s queue stays the one queue, and the cast keeps playing through a MusicBee restart. One Cast button on the HUD, Play and the dashboard.
• API keys — named, revocable credentials for other programs. Read or Read-write, with an explicit Execute grant for ARiA host automation, on the Remote Access tab.
• Play a whole list, an album or a genre in one call. POST /queue/play-list takes the urls and a position; POST /library/albums/{album}/play and /library/genres/{genre}/play resolve the tracks on the hub, so an automation can name a record and nothing else.
• Undo — take back what you just did. Ctrl+K on the web pages, Ctrl+Z in the AutoQ Workbench. One step back across queue, volume, mute, bans, ratings, love and skips.
• Immersive play — the artwork on the whole screen. A control in the corner of the cover fills the display, in a browser or in the HUD overlay; the details and transport fade over it.

Full changelog

Windows 10 or later · MusicBee 3.x · .NET Framework 4.8 · .NET 10.0 Desktop Runtime for MBXHub.exe

• EV4.3.1: Updated Network status in plugin settings.
• EV4.3.1: Cast to Google speaker groups — groups made in Google Home appear in the cast menu beside the individual speakers.
• EV4.3.1: Fixed: improved handling for casting between multiple instances by the same user.
• EV4.3: Artists and Genres lists can split multi-value tags — one row per person or genre (Browse setting).
• EV4.3: Play / Next / Last on track rows work again in the player page.
• EV4.2: Cast Control opens at a fixed height instead of filling the screen, and an overlay window that fails to open now logs why instead of failing silently.
• EV4.1: Revised /status page reporting.
• EV4: A reload button beside the mood model in Settings.
• EV4: Music Map fullscreen keeps the map square with the tools beside it on a wide screen, and works inside the HUD.
• EV4: The Music Map’s Song view shows the playing song and why it is playing.
• EV3: A better valence read: the mood model’s valence axis was retrained from side-by-side listening comparisons, so tracks spread across the whole range instead of piling up at the ends. Arousal is unchanged. No rescan needed.
• EV3: Choose the mood model: a new Model setting under AutoQ picks which mood model scores your tracks — Model 296 (the current model), Model 180 (the July 2026 model), or a model file you put in the hub’s data folder. Switching rescores your library on the spot; no rescan and no tag rewrite.
• EV3: Picking a mood while the radio is on the air now re-aims the run at it; the seeds, station and flow stay as they were.
• EV3: Fixed: on a portable install the Shell could pick up a neighbouring install’s TrueDat; and a queue request for a file that is not in the library is refused up front instead of failing when the row comes up to play.
• Smoother transitions: AutoQ matches the end of each track to the start of the next — key and tempo, including half and double time — using TrueDat’s start and end of track analysis. That analysis (edges) is off by default; without it, AutoQ matches on each track’s main key. A new Loudness Smoothing knob evens out volume jumps between tracks (on by default). Requires TrueDat 0.5.5.3 or later.
• Better track matching: with Prefer key-compatible on, AutoQ now picks tracks whose keys mix with the one before, instead of only reordering what it already chose. Applies to the radio, Fill, stations, Generate and journeys. On by default.
• Mood data straight from TrueDat: AutoQ can read TrueDat’s database directly, instead of waiting for TrueDat to export its file. Requires TrueDat 0.5.5.3 or later. Off by default; without it, AutoQ uses your mood file as before. The Workbench Mood tab tells you when your mood data is out of date.
• The AutoQ Workbench’s Features tab is refreshed: the music map now lives on the plot (library dots, the radio trail, the path ahead, hover for a track’s key, right-click to play), and the channel table moved into its own Edit channels… window.
• DV1: Roll the dice for a single track, not just an album — a new What it rolls choice on the dice page. A track roll never hands you the track already playing, and pairs with Start a station so the music keeps going.
• When MusicBee won’t start from the Shell or the HUD, it now says why.
• Fixed: a program plays each station for the time you set, then moves on. Starting a program replaces what was queued.
• Migration — the TrueDat store. TrueDat can keep its analysis in truedat.db, a SQLite database. Requires MBXHub and TrueDat 0.5.5.3 or later. Reading the store and the start-and-end-of-track analysis are both off by default; turn them on in Settings. Until TrueDat has built the database, MBXHub keeps using your existing mbxmoods.json. Clean install: truedat.exe --store --edges. Upgrade: truedat.exe --store-import, then truedat.exe --edges --refresh for transitions — the refresh re-analyzes every file.

The full changelog is served by the build itself once it is installed.
