>> 	+ doveadm sync/backup: Fixed -t parameter and added -e for "end date".

>> 	- auth: Cache keys didn't include %{passdb:*} and %{userdb:*}

>> 	  namespace prefix was non-empty.
>> 	- Fixed writing >2GB to iostream-temp files (used by fs-compress,
>> 	  fs-metawrap, doveadm-http)
>> 	- director: Ignore duplicates in director_servers setting.
>> 	- zlib, IMAP BINARY: Fixed internal caching when accessing multiple

>> 	- doveadm stats reset wasn't reseting all the stats.
>> 	- auth_stats=yes: Don't update num_logins, since it doubles them when
>> 	  using with mail stats.
>> 	- quota count: Fixed deadlocks when updating vsize header.
>> 	- dict-quota: Fixed crashes happening due to memory corruption.
>> 	- dict proxy: Fixed various timeout-related bugs.

>> 	- imap-hibernate: Fixed various failures when un-hibernating.
>> 	- fts: fts_autoindex=yes was broken in 2.2.25 unless
>> 	  fts_autoindex_exclude settings existed.
>> 	- fts-solr: Fixed searching multiple mailboxes (patch by x16a0)
>> 	- doveadm fetch body.snippet wasn't working in 2.2.25. Also fixed a
