Fixed crash in auth process when auth-policy was configured and authentication was aborted/failed without a username set.
director: If two users had different tags but the same hash, the users may have been redirected to the wrong tag’s hosts.
Index files may have been thought incorrectly lost, causing ‘Missing middle file seq=…’ to be logged and index rebuild. This happened more easily with IMAP hibernation enabled.
Various fixes to restoring state correctly in un-hibernation.
dovecot.index files were commonly 4 bytes per email too large. This is because 3 bytes per email were being wasted that could have been used for IMAP keywords.
Various fixes to handle dovecot.list.index corruption better.
lib-fts: Fixed assert-crash in address tokenizer with specific input.
Fixed assert-crash in HTML to text parsing with specific input (e.g. for FTS indexing or snippet generation)
doveadm sync -1: Fixed handling mailbox GUID conflicts.
sdbox, mdbox: Perform full index rebuild if corruption is detected inside lib-index, which runs index fsck.
quota: Don’t skip quota checks when moving mails between different quota roots.
search: Multiple sequence sets or UID sets in search parameters weren’t handled correctly. They were incorrectly merged together.
