发布周期

工作分两个分支完成：

The blender-v{VERSION}-release branch will be available for 5 weeks prior to the release date. At the same time will be open for the next release, giving 2 months to add documentation for new features of the next release, and another month to make improvements.

Bcon 阶段

Each Blender version has its own Bcon phase, indicating which types of changes are allowed to be committed and what writers are focusing on.

That means for example that Blender 2.90 can be in Bcon3 (wrapping up), while Blender 2.91 is in Bcon1 (new features and changes).
