+v2.2.27 2016-12-xx Timo Sirainen <tss@iki.fi>
+
+ * dovecot.list.index.log rotation sizes/times were changed so that
+ the .log file stays smaller and .log.2 is deleted sooner.
+
+ + Added mail_crypt plugin that allows encryption of stored emails.
+ See http://wiki2.dovecot.org/Plugins/MailCrypt
+ + stats: Global stats can be sent to Carbon server by setting
+ stats_carbon_server=ip:port
+ + imap/pop3 proxy: If passdb returns proxy_not_trusted, don't send
+ ID/XCLIENT
+ + Added generic hash modifier for %variables:
+ %{<hash algorithm>;rounds=<n>,truncate=<bits>,salt=s>:field}
+ Hash algorithm is any of the supported ones, e.g. md5, sha1, sha256.
+ Also "pkcs5" is supported using SHA256. For example: %{sha256:user}
+ or %{md5;truncate=32:user}.
+ + Added support for SHA3-256 and SHA3-512 hashes.
+ + config: Support DNS wildcards in local_name, e.g.
+ local_name *.example.com { .. } matches anything.example.com, but
+ not multiple.anything.example.com.
+ - 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.
+
+v2.2.26.0 2016-10-28 Timo Sirainen <tss@iki.fi>
+
+ - Fixed some compiling issues.
+ - auth: Fixed assert-crash when using NTLM or SKEY mechanisms and
+ multiple passdbs.
+ - auth: Fixed crash when exporting to auth-worker passdb extra fields
+ that had empty values.
+ - dsync: Fixed assert-crash in dsync_brain_sync_mailbox_deinit
+
+v2.2.26 2016-10-27 Timo Sirainen <tss@iki.fi>
+
+ * master: Removed hardcoded 511 backlog limit for listen(). The kernel
+ should limit this as needed.
+ * doveadm import: Source user is now initialized the same as target
+ user. Added -U parameter to override the source user.
+ * Mailbox names are no longer limited to 16 hierarchy levels. We'll
+ check another way to make sure mailbox names can't grow larger than
+ 4096 bytes.
+
+ + Added a concept of "alternative usernames" by returning user_* extra
+ field(s) in passdb. doveadm proxy list shows these alt usernames in
+ "doveadm proxy list" output. "doveadm director&proxy kick" adds
+ -f <passdb field> parameter. The alt usernames don't have to be
+ unique, so this allows creation of user groups and kicking them in
+ one command.
+ + auth: passdb/userdb dict allows now %variables in key settings.
+ + auth: If passdb returns noauthenticate=yes extra field, assume that
+ it only set extra fields and authentication wasn't actually performed.
+ + auth: passdb static now supports password={scheme} prefix.
+ + auth, login_log_format_elements: Added %{local_name} variable, which
+ expands to TLS SNI hostname if given.
+ + imapc: Added imapc_max_line_length to limit maximum memory usage.
+ + imap, pop3: Added rawlog_dir setting to store IMAP/POP3 traffic logs.
+ This replaces at least partially the rawlog plugin.
+ + dsync: Added dsync_features=empty-header-workaround setting. This
+ makes incremental dsyncs work better for servers that randomly return
+ empty headers for mails. When an empty header is seen for an existing
+ mail, dsync assumes that it matches the local mail.
+ + doveadm sync/backup: Added -I <max size> parameter to skip too
+ large mails.
+ + doveadm sync/backup: Fixed -t parameter and added -e for "end date".
+ + doveadm mailbox metadata: Added -s parameter to allow accessing
+ server metadata by using empty mailbox name.
+ + Added "doveadm service status" and "doveadm process status" commands.
+ + director: Added director_flush_socket. See
+ http://wiki2.dovecot.org/Director#Flush_socket
+ + doveadm director flush: Users are now moved only max 100 at a time to
+ avoid load spikes. --max-parallel parameter overrides this.
+ + Added FILE_LOCK_SLOW_WARNING_MSECS environment, which logs a warning
+ if any lock is waited on or kept for this many milliseconds.
+
+ - master process's listener socket was leaked to all child processes.
+ This might have allowed untrusted processes to capture and prevent
+ "doveadm service stop" comands from working.
+ - login proxy: Fixed crash when outgoing SSL connections were hanging.
+ - auth: userdb fields weren't passed to auth-workers, so %{userdb:*}
+ from previous userdbs didn't work there.
+ - auth: Each userdb lookup from cache reset its TTL.
+ - auth: Fixed auth_bind=yes + sasl_bind=yes to work together
+ - auth: Blocking userdb lookups reset extra fields set by previous
+ userdbs.
+ - auth: Cache keys didn't include %{passdb:*} and %{userdb:*}
+ - auth-policy: Fixed crash due to using already-freed memory if policy
+ lookup takes longer than auth request exists.
+ - lib-auth: Unescape passdb/userdb extra fields. Mainly affected
+ returning extra fields with LFs or TABs.
+ - lmtp_user_concurrency_limit>0 setting was logging unnecessary
+ anvil errors.
+ - lmtp_user_concurrency_limit is now checked before quota check with
+ lmtp_rcpt_check_quota=yes to avoid unnecessary quota work.
+ - lmtp: %{userdb:*} variables didn't work in mail_log_prefix
+ - autoexpunge settings for mailboxes with wildcards didn't work when
+ 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.
+ - director: Many fixes related to connection handshaking, user moving
+ and error handling.
+ - director: Don't break with shutdown_clients=no
+ - zlib, IMAP BINARY: Fixed internal caching when accessing multiple
+ newly created mails. They all had UID=0 and the next mail could have
+ wrongly used the previously cached mail.
+ - 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.
+ - doveadm proxying: Fixed -A and -u wildcard handling.
+ - doveadm proxying: Fixed hangs and bugs related to printing.
+ - imap: Fixed wrongly triggering assert-crash in
+ client_check_command_hangs.
+ - imap proxy: Don't send ID command pipelined with nopipelining=yes
+ - imap-hibernate: Don't execute quota_over_script or last_login after
+ un-hibernation.
+ - imap-hibernate: Don't un-hibernate if client sends DONE+IDLE in one
+ IP packet.
+ - 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
+ crash with certain emails.
+ - pop3-migration + dbox: Various fixes related to POP3 UIDL
+ optimization in 2.2.25.
+ - pop3-migration: Fixed "truncated email header" workaround.
+
+v2.2.25 2016-07-01 Timo Sirainen <tss@iki.fi>
+
+ * lmtp: Start tracking lmtp_user_concurrency_limit and reject already
+ at RCPT TO stage. This avoids MTA unnecessarily completing DATA only
+ to get an error.
+ * doveadm: Previously only mail settings were read from protocol
+ doveadm { .. } section. Now all settings are.
+
+ + quota: Added quota_over_flag_lazy_check setting. It avoids checking
+ quota_over_flag always at startup. Instead it's checked only when
+ quota is being read for some other purpose.
+ + auth: Added a new auth policy service:
+ http://wiki2.dovecot.org/Authentication/Policy
+ + auth: Added PBKDF2 password scheme
+ + auth: Added %{auth_user}, %{auth_username} and %{auth_domain}
+ + auth: Added ":remove" suffix to extra field names to remove them.
+ + auth: Added "delay_until=<timestamp>[+<max random secs>]" passdb
+ extra field. The auth will wait until <timestamp> and optionally some
+ randomness and then return success.
+ + dict proxy: Added idle_msecs=<n> parameter. Support async operations.
+ + Performance improvements for handling large mailboxes.
+ + Added lib-dcrypt API for providing cryptographic functions.
+ + Added "doveadm mailbox update" command
+ + imap commands' output now includes timing spent on the "syncing"
+ stage if it's larger than 0.
+ + cassandra: Added metrics=<path> to connect setting to output internal
+ statistics in JSON format every second to <path>.
+ + doveadm mailbox delete: Added -e parameter to delete only empty
+ mailboxes. Added --unsafe option to quickly delete a mailbox,
+ bypassing lazy_expunge and quota plugins.
+ + doveadm user & auth cache flush are now available via doveadm-server.
+ + doveadm service stop <services> will stop specified services while
+ leaving the rest of Dovecot running.
+ + quota optimization: Avoid reading mail sizes for backends which
+ don't need them (count, fs, dirsize)
+ + Added mailbox { autoexpunge_max_mails=<n> } setting.
+ + Added welcome plugin: http://wiki2.dovecot.org/Plugins/Welcome
+ + fts: Added fts_autoindex_exclude setting.
+ - v2.2.24's MIME parser was assert-crashing on mails having truncated
+ MIME headers.
+ - auth: With multiple userdbs the final success/failure result wasn't
+ always correct. The last userdb's result was always used.
+ - doveadm backup was sometimes deleting entire mailboxes unnecessarily.
+ - doveadm: Command -parameters weren't being sent to doveadm-server.
+ - If dovecot.index read failed e.g. because mmap() reached VSZ limit,
+ an empty index could have been opened instead, corrupting the
+ mailbox state.
+ - imapc: Fixed EXPUNGE handling when imapc_features didn't have modseq.
+ - lazy-expunge: Fixed a crash when copying failed. Various other fixes.
+ - fts-lucene: Fixed crash on index rescan.
+ - auth_stats=yes produced broken output
+ - dict-ldap: Various fixes
+ - dict-sql: NULL values crashed. Now they're treated as "not found".
+
+v2.2.24 2016-04-26 Timo Sirainen <tss@iki.fi>
+
+ * doveconf now warns if it sees a global setting being changed when
+ the same setting was already set inside some filters. (A common
+ mistake has been adding more plugins to a global mail_plugins
+ setting after it was already set inside protocol { .. }, which
+ caused the global setting to be ignored for that protocol.)
+ * LMTP proxy: Increased default timeout 30s -> 125s. This makes it
+ less likely to reach the timeout and cause duplicate deliveries.
+ * LMTP and indexer now append ":suffix" to session IDs to make it
+ unique for the specific user's delivery. (Fixes duplicate session
+ ID warnings in stats process.)
+
+ + Added dict-ldap for performing read-only LDAP dict lookups.
+ + lazy-expunge: All mails can be saved to a single specified mailbox.
+ + mailbox { autoexpunge } supports now wildcards in mailbox names.
+ + doveadm HTTP API: Added support for proxy commands
+ + imapc: Reconnect when getting disconnected in non-selected state.
+ + imapc: Added imapc_features=modseq to access MODSEQs/HIGHESTMODSEQ.
+ This is especially useful for incremental dsync.
+ + doveadm auth/user: Auth lookup performs debug logging if
+ -o auth_debug=yes is given to doveadm.
+ + Added passdb/userdb { auth_verbose=yes|no } setting.
+ + Cassandra: Added user, password, num_threads, connect_timeout and
+ request_timeout settings.
+ + doveadm user -e <value>: Print <value> with %variables expanded.
+ - Huge header lines could have caused Dovecot to use too much memory
+ (depending on config and used IMAP commands). (Typically this would
+ result in only the single user's process dying with out of memory
+ due to reaching service { vsz_limit } - not a global DoS).
+ - dsync: Detect and handle invalid/stale -s state string better.
+ - dsync: Fixed crash caused by specific mailbox renames
+ - auth: Auth cache is now disabled passwd-file. It was unnecessary and
+ it broke %variables in extra fields.
+ - fts-tika: Don't crash if it returns 500 error
+ - dict-redis: Fixed timeout handling
+ - SEARCH INTHREAD was crashing
+ - stats: Only a single fifo_listeners was supported, making it
+ impossible to use both auth_stats=yes and mail stats plugin.
+ - SSL errors were logged in separate "Stacked error" log lines
+ instead of as part of the disconnection reason.
+ - MIME body parser didn't handle properly when a child MIME part's
+ --boundary had the same prefix as the parent.
+
+v2.2.23 2016-03-30 Timo Sirainen <tss@iki.fi>
+
+ - Various fixes to doveadm. Especially running commands via
+ doveadm-server was broken.
+ - director: Fixed user weakness getting stuck in some situations
+ - director: Fixed a situation where directors keep re-sending
+ different states to each others and never becoming synced.
+ - director: Fixed assert-crash related to a slow "user killed" reply
+ - Fixed assert-crash related to istream-concat, which could have
+ been triggered at least by a Sieve script.
+
+v2.2.22 2016-03-16 Timo Sirainen <tss@iki.fi>
+
+ + Added doveadm HTTP API: See
+ http://wiki2.dovecot.org/Design/DoveadmProtocol/HTTP
+ + virtual plugin: Mailbox filtering can now be done based on the
+ mailbox metadata. See http://wiki2.dovecot.org/Plugins/Virtual
+ + stats: Added doveadm stats reset to reset global stats.
+ + stats: Added authentication statistics if auth_stats=yes.
+ + dsync, imapc, pop3c & pop3-migration: Many optimizations,
+ improvements and error handling fixes.
+ + doveadm: Most commands now stop soon after SIGINT/SIGTERM.
+ - auth: Auth caching was done too aggressively when %variables were
+ used in default_fields, override_fields or LDAP pass/user_attrs.
+ userdb result_* were also ignored when user was found from cache.
+ - imap: Fixed various assert-crashes caused v2.2.20+. Some of them
+ caught actual hangs or otherwise unwanted behavior towards IMAP
+ clients.
+ - Expunges were forgotten in some situations, for example when
+ pipelining multiple IMAP MOVE commands.
+ - quota: Per-namespaces quota were broken for dict and count backends
+ in v2.2.20+
+ - fts-solr: Search queries were using OR instead of AND as the
+ separator for multi-token search queries in v2.2.20+.
+ - Single instance storage support wasn't really working in v2.2.16+
+ - dbox: POP3 message ordering wasn't working correctly.
+ - virtual plugin: Fixed crashes related to backend mailbox deletions.
+
v2.2.21 2015-12-11 Timo Sirainen <tss@iki.fi>
- doveadm mailbox list (and some others) were broken in v2.2.20
