Introduce stateVersion concept With upcoming changes to the dovecot home and maildirectories we need to introduce a way to nudge users to inform themselves about manual migration steps they might need to carry out. The idea here is to allow us to safely make breaking changes and notify the user of required migration steps at eval time, so they can make the necessary changes in time. 2025-05-22 02:45:55 +02:00			`# Testing eval failures that result from stateVersion assertion is out of scope`
