+       * fts-solr: Removed break-imap-search parameter
+       + Added more events for the new statistics, see
+         https://doc.dovecot.org/admin_manual/list_of_events/
+       + mail-lua: Add IMAP metadata accessors, see
+         https://doc.dovecot.org/admin_manual/lua/
+       + Add event exporters that allow exporting raw events to log files and
+         external systems, see
+         https://doc.dovecot.org/configuration_manual/event_export/
+       + SNIPPET is now PREVIEW and size has been increased to 200 characters.
+       + Add body option to fts_enforced. This triggers building FTS index only
+         on body search, and an error using FTS index fails the search rather
+         than reads through all the mails.
+       - Submission/LMTP: Fixed crash when domain argument is invalid in a
+         second EHLO/LHLO command.
+       - Copying/moving mails using Maildir format loses IMAP keywords in the
+         destination if the mail also has no system flags.
+       - mail_attachment_detection_options=add-flags-on-save caused email body
+         to be unnecessarily opened when FETCHing mail headers that were
+         already cached.
+       - mail attachment detection keywords not saved with maildir.
+       - dovecot.index.cache may have grown excessively large in some
+         situations. This happened especially when using autoexpunging with
+         lazy_expunge folders. Also with mdbox format in general the cache file
+         wasn't recreated as often as it should have.
+       - Autoexpunged mails weren't immediately deleted from the disk. Instead,
+         the deletion from disk happened the next time the folder was opened.
+         This could have caused unnecessary delays if the opening was done by
+         an interactive IMAP session.
+       - Dovecot's TCP connections sometimes add extra 40ms latency due to not
+         enabling TCP_NODELAY. HTTP and SMTP/LMTP connections weren't
+         affected, but everything else was. This delay wasn't always visible -
+         only in some situations with some message/packet sizes.
+       - imapc: Fix various crash conditions
+       - Dovecot builds were not always reproducible.
+       - login-proxy: With shutdown_clients=no after config reload the
+         existing connections could no longer be listed or kicked with doveadm.
+       - "doveadm proxy kick" with -f parameter caused a crash in some
+         situations.
+       - Auth policy can cause segmentation fault crash during auth process
+         shutdown if all auth requests have not been finished.
+       - Fix various minor bugs leading into incorrect behaviour in mailbox
+         list index handling. These rarely caused noticeable problems.
+       - LDAP auth: Iteration accesses freed memory, possibly crashing
+         auth-worker
+       - local_name { .. } filter in dovecot.conf does not correctly support
+         multiple names and wildcards were matched incorrectly.
+       - replicator: dsync assert-crashes if it can't connect to remote TCP
+         server.
+       - config: Memory leak in config process when ssl_dh setting wasn't
+         set and there was no ssl-parameters.dat file.
+         This caused config process to die once in a while
+         with "out of memory".
