By default, users are on the default branch (configured via git config).

There should be a setting to pick either:

1. Default branch: usual approach.
2. A stable major release: updates to all minor and patch updates).
3. A specific stable release version: no automatic changes, there will only be a forced update to the latest version on YY0M if there is a security patch. For example: if on 2603.1.1, it will be updated to 2603.9.1 if there was a vulnerability.

The changelog should support showing changes specific between last and new version (I think it already works for this).
