-We are currently in the process of updating the code-base to use the
-wlroots scene-graph API and have decided to use three branches at this
-time:
-
-- `v0.5` - the last minor release before the move to scene-graph. It is
-  not envisaged that new major features will be added on that branch.
-
-- `scene-graph` - where the active porting is taking place until it is
-  merged into master at which point the scene-graph branch will be
-  removed.
-
-- `master` - which is mostly frozen to make the rebase/merge a bit
-  easier.
+On the `master` branch we have moved across to the wlroots scene-graph
+API and as a result there is likey to be a period of instability and
+regression. A `v0.5` branch has been created as a stable pre-scene-graph
+branch, but it is not envisaged that new major features will be added on
+that branch.
