1.0.5-alpha:

Changes:

Add shape tweens (morph vector geometry between keyframes)
Fix motion tweens for groups and movie clips
Group geometry and Convert to Movie Clip now work on DCEL vector shapes
Region/lasso select now cuts the shape and feeds the normal selection, so Group, Convert, Delete and Properties all work from a lasso (hold shift to add to the selection)
Clip instances now draw on top of a layer's loose shapes
Add onion skinning for raster and vector layers, with tinted ghosts and settings in the Info Panel
Images can now fill vector shapes (None / Solid / Gradient / Image fill types)
Imported images can be placed on the canvas
Add a raster keyframe timeline UI with explicit keyframe creation; click a keyframe diamond to snap the playhead to it
Stream audio, video and images to and from the project file instead of holding them in memory, supporting arbitrarily long media
Persist (and resume) waveforms and video thumbnails in the project file
Use low-res proxies for fast cold scrubbing of raster frames
Bound memory use for raster pixels, GPU textures, video frames and decoded images on large projects
Video export is roughly 4x faster
Downmix surround video audio to stereo
