What shipped, and when

Rigging closed the gap to DUIK and Rive, and expressions grew coordinate spaces.

• Auto-rig presets for biped and quadruped: bones, IK chains and controllers in one operation.
• Per-chain IK/FK switching, and the conversion preserves the pose.
• Controllers — the DUIK posing layer, built against a real rig model rather than nulls and expressions.
• Per-vertex numeric weight editing, the last named gap against DUIK and Rive.
• Bend pins: a puppet pin whose position derives from the others.
• Motion Sketch, Exponential Scale, and Convert Expression to Keyframes.
• An expression can be disabled without being deleted.
• toComp, toWorld, fromComp and fromWorld in expressions.
• Guide layers: visible in the composition, excluded from every export.
• Animated dash offset, and Bezier Warp with a Coons-patch interior.
• On-canvas handles for effect centres.

The effects breadth pass: twenty new effects, and path operators became a real chain.

• The blur family: Gaussian, Fast Box, Radial.
• The colour family: Exposure, Vibrance, Colorama.
• The stylize family: Mosaic, Find Edges, Roughen Edges.
• The keying and matte family: Set Matte, Simple Choker, Linear Color Key, Shift Channels.
• The transition family: Venetian Blinds, Gradient Wipe, Card Wipe.
• Lens Flare, Numbers, Timecode and Audio Spectrum — with the honest limit on the last two stated in the code.
• Path operators became an ordered, stackable chain (schema 1.3.0), so operators survive a reorder.

Compositing reached 36 of After Effects' 38 blend modes, and templates got protected time.

• Stencil and Silhouette modes, bringing blend modes to 36 of AE's 38.
• Scope an individual effect to a mask region.
• Protected time regions in templates, with a marking UI.
• The repeater's three missing parameters: per-copy anchor, start offset, composite order.
• Wiggle Paths gained its time term and actually wiggles.
• Live boolean merge wired into the menus.
• Scale a keyframe selection in time.
• The local edition stopped shipping the assistant it could not key.

Packaging and release-pipeline fixes on top of the first public build.

• Installer and auto-update corrections for the first tagged releases.

The first public build: macOS and Windows, open source under AGPL-3.0.

• Compositions, keyframes, the graph editor, text animators, Classic 3D, rigging, particles and the deterministic export pipeline.
