 Blender 2.8 - The Workflow Release
The next major version!
Other 2.8 projects:
- Assets Integration
- Layers and Collections
- OpenGL Upgrade (2.1 -> 3.3)
Non trivial features are usually developed in their own new branches. When finished, they may be approved and merged back into the master branch.
The same happens with special versions of Blender, like the ones used (upgraded and adapted) in Blender Institute movie productions.
- A highlight of official branches
Python scripting is a very powerful feature in Blender, both for key functionality (the User Interface, for example) and for plugins that can greatly extend the program's capabilities.
