 This project follows a Git Flow-like scheme for branch management. Any branches where new features are being developed should be prepended with `feature/`; however that's the only practice that has been adopted.
 
-- **master** - This branch contains the current development version of BZiON.
-- **0.10-stable** - This branch contains the latest stable `0.10.x` code.
-  - Hot fixes will go to this branch for quick releases.
-  - New releases will be merged into this branch from the `master` branch.
+- **master** - This branch contains the current development version (`0.10.x`) of BZiON and should **always** be kept stable; features in development belong in their own feature branches.
 - **0.9** - This branch has been retired and contains the latest development version of the `0.9.x` pipeline.
 - **0.1** - This branch contains legacy code for a very early attempt of BZiON. This branch is only around for historical purposes.
