+v2.3.8 2019-10-08 Aki Tuomi <aki.tuomi@open-xchange.com>
+
+ + Added mail_delivery_started and mail_delivery_finished events, see
+ https://doc.dovecot.org/admin_manual/list_of_events/ for details.
+ + dsync-replication: Don't replicate users who have "noreplicate" extra
+ field in userdb.
+ + doveadm service status: Show total number of processes created.
+ + When logging to syslog, use instance_name setting's value for the
+ ident. This commonly is added as a log prefix.
+ + Base64 encoding/decoding code was rewritten with additional features.
+ It shouldn't cause any user visible changes.
+ - v2.3.7 regression: If a folder only receives new mails without any
+ other mail access, dovecot.index.log keeps growing forever and
+ dovecot.index keeps being rewritten for every mail delivery.
+ - dsync-replication may lose keywords after syncing mails restored from
+ another replica. This only happened if the mail only had keywords and
+ no system flags.
+ - event filters: Non-textual event fields could not be filtered using
+ wildcards.
+ - auth: Scope parameter was missing from OAuth password grant
+ request.
+ - doveadm client-server communication may hang in some situations.
+ It is also using unnecessarily small TCP/IP packet sizes.
+ - doveadm who and kick did not flush protocol output correctly.
+ - imap: SETMETADATA with literal value would delete the metadata value
+ instead of updating it.
+ - imap: When client issues FETCH PREVIEW (LAZY=FUZZY) command, the
+ caching decisions should be updated so that newly saved mails will
+ have the preview cached.
+ - With mail_nfs_index=yes and/or mail_nfs_storage=yes setuid/setgid
+ permission bits in some files may have become dropped with some NFS
+ servers. Changed NFS flushing to now use chmod() instead of chown().
+ - quota: warnings did not work if quota root was noenforcing
+ - acl: Global ACL file ignored the last line if it didn't end with LF.
+ - doveadm stats dump: With JSON formatter output numbers using the
+ number type instead of as strings
+ - lmtp_proxy: Ensure that real_* variables are correctly set when using
+ lmtp_proxy.
+ - event exporter: http-post driver had hardcoded timeout and did not
+ support DNS lookups or TLS connections.
+ - auth: Fix user iteration to work with userdb passwd with glibc v2.28.
+ - auth: auth service can crash if auth-policy JSON response is invalid
+ or returned too fast.
+ - In some rare situations "ps" output could have shown a lot of "?"
+ characters after Dovecot process titles.
+ - When dovecot.index.pvt is empty, an unnecessary error is logged:
+ Error: .../dovecot.index.pvt reset, view is now inconsistent
+ - SMTP address encoder duplicated initial double quote character when
+ the localpart of an address ended in '..'. For example
+ "user+..@example.com" became ""user+.."@example.com in a
+ sieve redirect.
+
+v2.3.7.1 2019-07-23 Timo Sirainen <timo.sirainen@open-xchange.com>
+
+ - Fix TCP_NODELAY errors being logged on non-Linux OSes
+ - lmtp proxy: Fix assert-crash when client uses BODY=8BITMIME
+ - Remove wrongly added checks in namespace prefix checking
+
+v2.3.7 2019-07-12 Aki Tuomi <aki.tuomi@open-xchange.com>
+
+ * 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".
