Semantic Versioning

Starting with the tag v07_07_00 Mu2e has adopted semantic versioning. Prior to that version, we did not have a well defined policy for when to update which field within the version number.

A tag now has the form: vxx_yy_zz, where "xx", "yy" and "zz" are two digit numeric fields with leading zeros present. These 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

We do not tag every commit or pull request; we only tag when we need to document the state of the repository for future reference. If there are both bug fixes and new features since the previous tag, then the tag will be considered a new feature and yy will be incremented. Upgrading to a new version of an underlying ups product, such as art or root, is treated the same way: if the upgrade is solely a bug fix, then increment zz; if the upgrade adds new features then increment yy; and if there are breaking changes increment xx.
