PyInstaller’s Branch Model

develop branch:We consider origin/develop to be the main branch where the source code of HEAD always reflects a state with the latest delivered development changes for the next release. Some would call this the “integration branch”.
master branch:We consider origin/master to be the main branch where the source code of HEAD always reflects a production-ready state. Each commit to master is considered a new release and will be tagged.

The PyInstaller project doesn’t use long living branches (beside master and develop) as we don’t support bugfixes for several major releases in parallel.

Occasionally you might find these branches in the repository: [1]

release/ branches:
 These branches are for preparing the next release. This is for example: updating the version numbers, completing the change-log, recompiling the bootloader, rebuilding the manuals. See ref:release-workflow for details about the release process and what steps have to be performed.
hotfix/ branches:
 These branches are also meant to prepare for a new production release, albeit unplanned. This is what is commonly known as a “hotfix”.
feature/ branches:
 Feature branches (or sometimes called topic branches) are used to develop new features for the upcoming or a distant future release.
[1]This branching-model is basically the same as Vincent Driessen described in this blog. But currently we are not following it strictly.
