No, at least Emacs and glibc have maintenance releases. In Emacs some patches are applied to the emacs-23 branch, and someone occasionally merges them into 'master'. A 'pending' branch holds patches waiting to get into 'master'. But the 'pending' branch is rarely used (two changes since July) and the emacs-23 branch is strictly for the old release. The main development is all in 'master'. After Emacs 24 comes out, a new emacs-24 branch will be created for it. In glibc there is a separate branch for every release, and as I understand it these primarily cherry-pick fixes back from 'master'. The main development is on 'master'.
