Branch Model

OpenStack branch model

Starting with the Diablo cycle, OpenStack core projects use a branching model close to the NVIE model that ensures a continuously-open trunk while still allowing to freeze features and select bugfixes in a release branch (milestone-proposed):

At some point before the release of a milestone (called the "branch point"), the current state of trunk is merged into milestone-proposed, and trunk continues towards the development of the next milestone. The milestone-proposed branches gets testing and bugfixes (that are also backported to trunk), until the release is tagged.

Here are pointers to the branches:

Project	trunk
Nova	lp:nova
Glance	lp:glance
Swift	lp:swift
