Versioning

We are using so-called calendar versioning in the format YY.MM.PATCH.

• YY stands for the current year.
• MM stands for the current month.
• PATCH is increased on every release in the given month.

Examples

• 20.10.1 first release in Oct 2020
• 20.10.3 third release in Oct 2020
• 19.12.1 first release in Dec 2019

Beta versions

We version beta in a similar way as production versions but we always set PATCH to 0 and increase the MM.

That means that every release on beta has 0 as the patch version. This has a drawback that you can't distinguish beta deployments by a version number, but beta testers should be able to read and report the commit hash.

Only stable releases have patch version >1 and this increases with each stable release: 1, 2, 3, 4.

Beta also has +1 MM version when compared to stable indicating this is upcoming release which will be deployed on stable next month.

Examples

• 20.10.1 first release on Oct 15th to stable
• 20.10.2 second release on Oct 22nd to stable
• 20.11.0 release on Oct 29th 2020 to beta
• 20.11.0 another release on Nov 5th to beta
• 20.11.1 public release on Nov 14th to stable

Develop versioning

We use the same scheme as beta. That is, develop branch has always YY.MM.0 version where MM is the upcoming month's release. When we fork develop to release/20YY-MM branch, we bump the release branch version to YY.MM.1 and increase the develop version to YY.(MM+1).0 indicating we are already brewing next release in the develop.
