Pigeonhole does not follow a documented release policy for its own. It follows the same cycle as Dovecot does, even if that means to do a release without changes to keep version numbers synced.
Since v2.4.0 (released in 2025) the version numbering scheme is also aligned to match Dovecot’s scheme.

You should be running one of the supported release numbers listed above in the rightmost column.
