The latest development version is kept in the master branch.

Each major version will be stored as a separate branch. These branches are named as v1.22 where 1.22 is the version number. The version branches are updated when bugs are fixed against old versions.

Every release in the version branch is marked with a tag. These tags are named with the version number followed by the patch level. For example, the first release in branch v1.22 will be named 1.22, the second one will be 1.22.1 and third one will be 1.22.2.
