[RFC] Release branches for unity-system-compositor

[Daniel van Vugt]

Indeed multi-series development is an overlapping activity.

If you consider the Mir 0.14.0 release we're trying to get out the door 
right now, most of what's gone into that is dated 1 May to 23 June (tags 
br0.13..br0.14). That does not mean the team has been sitting on their 
hands since 23 June.

To keep the team moving seamlessly we just branched 0.14 around 23 June 
so that work on lp:mir (0.15) can keep going at full speed while 
simultaneously providing a "freeze" point for the 0.14.0 release to 
stabilise in its own branch. And just as well because we've (anpok) been 
trying to fix and release 0.14 for a month so far. If we were trying to 
release from lp:mir the situation would be even more fluid and it would 
be much more difficult to stabilise and release.

Branches are free and cheap. And they improve team productivity as well 
as code reliability. All you need to manage them is a keen eye on your 
bug tracker to accurately represent the status of the different 
branches, and fortunately we have the best tool in the world for that, 
with Launchpad.
