 Other branches
 ==============
 
-Django uses branches for two main purposes:

+:term:`micro <Micro release>`).

+done on contributor's forks, but the Subversion feature branches remain in Git
+for historical reference.
 
-2. Security and bugfix support for older releases of Django, during
+Stable branches
-   their support lifetimes.
+---------------
+
+These branches can be found in the repository as ``stable/A.B.x``
+branches and will be created right after the first alpha is tagged.
+
+For example, immediately after *Django 1.5 alpha 1* was tagged, the branch
+``stable/1.5.x`` was created and all further work on preparing the code for the
+final 1.5 release was done there.
+
+These branches also provide limited bugfix support for the most recent released
+version of Django and security support for the two most recently-released
+versions of Django.
+
+For example, after the release of Django 1.5, the branch ``stable/1.5.x``
+receives only fixes for security and critical stability bugs, which are
+eventually released as Django 1.5.1 and so on, ``stable/1.4.x`` receives only
+security fixes, and ``stable/1.3.x`` no longer receives any updates.
+
+.. admonition:: Historical information
+
+    This policy for handling ``stable/A.B.x`` branches was adopted starting
+    with the Django 1.5 release cycle.
+
+    Previously, these branches weren't created until right after the releases
+    and the stabilization work occurred on the main repository branch. Thus,
+    no new features development work for the next release of Django could be
+    committed until the final release happened.
+
+    For example, shortly after the release of Django 1.3 the branch
+    ``stable/1.3.x`` was created. Official support for that release has expired,
+    and so it no longer receives direct maintenance from the Django project.
+    However, that and all other similarly named branches continue to exist and
+    interested community members have occasionally used them to provide
+    unofficial support for old Django releases.

-This support is provided via branches in which the necessary bug or security
