What changed in recent development builds.

These notes cover changes to the development builds ahead of the first Windows release, listed by date.

Settings is organised around models, with five sections: Models, Defaults, Ape, Extensions and Advanced. Adding a model from a provider preset and adding a custom model now happen in the same place.
Grapple ships with one Python runtime for model adapters and effects. Provider packages install separately, so they can't change the bundled runtime.
Create keeps its standard pages visible even before a model is connected, and adds a page for any other operation a connected model offers. Values you have typed survive form refreshes.
Image, video and audio results from models are checked and written straight into the project with a record of the run.
The command-line tool can run the editor's project operations on a project folder, using a JSON arguments file.
Opening a nested composition now shows the correct time inside it.

Preview can play proxy versions of heavy video.
You can send Ape a note while a run is in progress.
Roto moved into the Stage toolbar (W), with the list of masks and per-frame corrections in Properties.
Masks from 16-bit and floating-point sources keep their full precision.

Pen, Paint and Subject masks all work from the Roto tool, and vector and subject masks share the same tracking controls, tracking frame by frame through a range you set.
Paint strokes can apply to the current frame or the whole clip.
Masks keep their animation and tracking when footage is moved or trimmed on the timeline. Copied and split clips get masks you can edit separately.
Puppet: create a mesh from a layer and pose it with pins on the Stage.

Ape can look up the fonts installed on your computer when it sets text.
Path trim and path-follow motion measure curves the same way, so a layer following a path lines up with the drawn line.
The History panel pages through long projects with readable status and controls.

The first public release is for Windows x64. See the roadmap for what it includes, and the download page for availability.

Pick a short clip and one job, such as a lower third or a trimmed opening. The getting-started guide takes you from import to an exported file.
