Most stories about Git (also about scrum BTW) deal with a product where 
one version follows the next in a linear way.

The challenge with adapting things for TYPO3 is that we currently have a 
development line (trunk/master) which will become the next major 
release, but also provide support for three older versions.

Patches have to be applied to a mix of versions. Sometimes they are easy 
to apply (code not changed between versions), sometimes a bit harder 
(code changed), sometimes really complicated (code completely rewritten) 
or even impossible.

With 4.5LTS it will even result in the situation that later versions 
will not be supported any more while the LTS version is still alive 
(assuming 4.x is still around in 2014).

Yesterday I found that I couldn't apply a change in master (by fetching) 
into 4_5 without getting all kinds of extra code also. This indicates 
that it will take quite some effort to make a working model for these 
kind of advanced branching situations between the supported TYPO3 versions.

Making a release branch at feature freeze would be a nice idea. 
Development could even continue in some areas, while bugfixing takes 
place in this branch. After the release the release branch can be 
removed. It only requires reliable, automatic merging from release 
branch into development branch (in our case in Gerrit) or a lot of extra 
manual work.
