 # Versions
 
 New versions of TeraFlowSDN are periodically released.
 Each release is properly tagged and a branch is kept for its future bug fixing, if needed.
 
-- The branch *master*, points always to the latest stable version of the TeraFlowSDN controller.
-- The branches *release/X.Y.Z*, point to the code for the different release versions indicated in branch name.
-  - Code in these branches can be considered stable, and no new features are planned.
-  - In case of bugs, point releases increasing revision number (Z) might be created.
-- The main development branch is named as *develop*.
-  - **Use with care! Might not be stable.**
-  - The latest developments and contributions are added to this branch for testing and validation before reaching a release.
