Cockroach Labs uses a three-component calendar versioning scheme to name production releases of CockroachDB. The format is
YY indicates the year,
R indicates release with “1” for Spring and “2” for Fall, and
PP indicates the patch release version. Example: Version 20.1.1 (abbreviated v20.1.1).
This calendar versioning scheme began with v19.1. Prior releases use a different versioning scheme.
A major release is produced twice a year indicating major enhancements to product functionality. A change in the
YY.Rcomponent denotes a major release.
A patch (or maintenance) release is produced to roll out critical bug and security fixes. A change in the
PPcomponent denotes a patch release.
