* Add node animation playback to SubModels dialog.
* Media-compatibility "Convert Now" now special-cases animated GIFs that were used as Video effects and turns them into normal Pictures effects that properly handle animated GIFs
* Timing tracks: new "Audio Chords" option in the "Add Timing Track" dialog. Builds a chromagram, matches against 24 major/minor templates, estimates key via Krumhansl–Schmuckler, and drops a variable timing track whose back-to-back marks are labelled with the detected chord names.
* Timing tracks: new "Audio Tempo" option in the "Add Timing Track" dialog runs autocorrelation on the audio's onset envelope, confirms the detected BPM, and drops a fixed timing track with back-to-back marks at each beat.
* Waveform (macOS 12+): four new "Stem — Drums / Bass / Other / Vocals (ML)" right-click filters run Apple CoreML inference against HTDemucs to split the audio into its constituent parts.
* Waveform: "Classify Audio…" right-click entry runs Apple's SNClassifySoundRequest offline and lets you pick a detected class (drums, vocals, guitar, …); the waveform then scales to show amplitude only where that class is present.
* Waveform: Several new options to display the waveform as spectrograph, filtering, loudness, etc....
* Shape effect: Effect panel now organises its 27 properties into Shape / Size / Motion / Triggers tabs instead of a flat scroll, matching the grouped layout other large effects use.
* Value curve Exponential, Logarithmic, and Parabolic types now support Start/End.
* Add "Show Names" and "Show Start Channel" checkboxes to Layout tab to display model names and controller/port or start channel in the layout preview
* Add timing track trigger for Shockwave effect
* Better cube visualizion for dumb rgb
* Show losso box when selecting props in 3D
* Show warning if you set String property when Controller color order is available
* Up the pixielink port count capability
* Add new Label text model
* Add optional image to custom models
* Picture effect auto-sets scaling to "Scale To Fit" when appropriate
* Add Speed as a Warp effect type
* Add more variability to Lines Effect. Now using float values
* Include Line Count in Submodel dialogs
* Render: RenderProgressInfo now self-signals completion via an atomic flag
* Fix state/face definitions copied in layout not rendering in sequence until restart
* Layout was sizing groups and model names too quickly
* Fix ON effect was resetting the intensity values
* Fix visualizer clearing all models
* Twinkly was blocking the render when devices were offline
* Fix copy-paste model not assigning the next available start channel
* Metal render: drain autoreleased MTLCommandEncoders per frame instead of per render-job (large memory growth during long renders), fix sparkleBuffer use-after-free, and release retained Metal objects at shutdown
* Handle various codec issues in avi conversions (#6142, #6153)
* Fix Use State as Outline for Face Effect default
* New polyline with default drop pattern did not render
* ESPixelStick: clear unused ports when uploading with FullxLights Control
* Fix base show folder merge not detecting child element changes
* Preserve Layer Blending and Settings when using Random Effects
* Honour 2D to 3D Layout changing
* Fix pixel sizing appearing zoomed in
* Downloadeded models now placed where you drop them
* Random Value Curve now holds the value properly
* Fix layout render glitches by sorting pixels back-to-front by camera-space Z
* Restore performance of House Preview Export to Video
* Fix several potential crashes with invalid parameters
* Package Sequence: rewritten to walk SequenceMedia + every model/view-object's file references + Matrix face images so shaders, custom images, videos, meshes, and face/state assets are actually included.
* Packaging preferences: "Exclude Presets" renamed to "Exclude Videos" — the old option stripped a rgbeffects element that no longer carries presets, so it was a no-op;
