Tag conventions

Tags are used to capture the state of the repo, for published builds and documentation.

Tags use semantic versioning. A tag has the form: Lxx_yy_zz, where "L" represents one lower case letter, "xx", "yy" and "zz" are two digit numeric fields with leading zeros present.

The letter "L" has the meaning

• v: offline use (simulation, analysis)
• d: DAQ or online
• s: snowmass or Mu2eII

The numbers have the meanings:

• xx: major version number; incremented when there is a breaking change.
• yy: minor version number; incremented when a new feature is added.
• zz: patch number; incremented when a bug fix is made

Which Should I Use?

If you are starting a new development project, use the head of master and follow the instructions at GitHubWorkflow.

If you want to run a simulation campaign using the most recent stable release, start from the tag v08_04_00:

setup mu2e
git clone git@github.com:Mu2e/Offline
cd Offline
git checkout -b <branch name> v08_04_00
source setup.sh
scons -j 8

If you want to develop code starting from v08_04_00 and plan to make pull request to put that code at the head of master, speak with Rob and Dave before you begin.
