Branches and Tags in the Git Repo
OpenSimulator uses Git for its source code repository. The repository contains various branches and tags used to identify development branches and release branches of the code. The primary git repository is hosted on the opensimulator.org domain. A mirror is maintained on Github. The Github repo is sync'ed with the primary every 10 minutes.
Git Repos
Repositories in the Primary Git
- opensim - the OpenSimulator source code
- opensim-libs - forks of third party libraries used in building OpenSimulator
This page outlines the repository branches and tags; what they are for, and our policy for what goes into it.

Branches
master
The master branch holds bleeding edge OpenSimulator development.
OpenSimulator Master Branch Policies
- Master is not guaranteed to function. It might be in the middle of a transition, or undergoing a major overhaul.
- Master should always build
- All tests should run green on trunk
- Code should have been reasonably tested

New major Releases
A new release is created for main master code.
- A tag with the full release name is added. (example 0.9.1.1).
- A Branch named as the release number is created.
- Master version is changed to at least the next minor number.
New minor Releases
Minor releases will contain small changes or more fixes to previous release.
In many cases master branch does correspond to the required release in this case it is just like a new release
On occasions it may be required to only include selected commits or even unique special code, in this case:
- change (checkout) to the branch of release to be fixed (or tag on main)
- Increment its minor version number(s).
- Create a new branch named as that version.
- do the fixes
- release
Release Candidates
Release candidates should be just snapshots of main code
except any special reason, they may have at most a TAG on it
Old procedure ( prior to 0.9x)
Old procedure used extra names like '-Release' and '-postfixes' after the version name.
All releases should have their own version number.
Lower digits of a version name are clear and enough identification for minor changes and bug fixes
Something like 0.7.0.1-Release and 0.7.0.1-post-fixes was just redundant and confusing
Under new format this would be just 0.7.0.1 and 0.7.0.2
Other Branches
Other branches mainly contain temporary development work, for example to develop new code without disturbing current master.

Tags
Tags were originally used to trigger the automatic release build process. When it was time for a release, a <version>-release tag was applied to a branch, triggering the automated process that produced the release tarballs. For more details see Automated Release Building. Tags continue to be used to mark releases but may also be used for other purposes.
