I still get the old error:

I am still seeing this issue in startup logs:
LOGS: dovecot[16466]: config: Warning: sieve: Invalid address value for setting
`sieve_user_email': Missing domain
CONF: plugin { sieve_user_email = %u }
DOCS: %u = full username (e.g. user at domain)


And i notice a new error i have not seen in previous versions.
dovecot[16462]: master: Warning: Corrected permissions for login directory
/var/run/dovecot/token-login
However i only got this error twice, subsequent restarts do not give this error
anymore so maybe it's nothing to worry about.

This release still needs the following patch to build on (newer) macOS:
