Versioning Scheme

This page describes FireFly's versioning scheme

Semantic versioning

FireFly follows semantic versioning. In summary, this means:

Given a version number MAJOR.MINOR.PATCH, increment the:

  • MAJOR version when you make incompatible API changes,
  • MINOR version when you add functionality in a backwards compatible manner, and
  • PATCH version when you make backwards compatible bug fixes.
  • Additional labels for pre-release and build metadata are available as extensions to the MAJOR.MINOR.PATCH format.

When creating a new release, the release name and tag should be the semantic version should be prefixed with a v . For example, a certain release name/tag could be v0.9.0.

Pre-release test versions

For pre-release versions for testing, we append a date and index to the end of the most recently released version. For example, if we needed to create a pre-release based on v0.9.0 and today's date is October 22, 2021, the version name/tag would be: v0.9.0-20211022-01. If for some reason you needed to create another pre-release version in the same day (hey, stuff happens), the name/tag for that one would be v0.9.0-20211022-02.

Candidate releases

For pre-releases that are candidates to become a new major or minor release, the release name/tag will be based on the release that the candidate will become (as opposed to the test releases above, which are based on the previous release). For example, if the current latest release is v0.9.0 but we want to create an alpha release for 1.0, the release name/tag would be v1.0.0-alpha.1.
