More fixes to automatically fix corruption in dovecot.list.index
dsync-server: Fix support for dsync_features=empty-header-workaround
imapc: Various bugfixes, including infinite loops on some errors
IMAP NOTIFY wasn't working for non-INBOX if IMAP client hadn't
enabled modseq tracking via CONDSTORE/QRESYNC.
fts-lucene: Fix it to work again with mbox format
Some internal error messages may have contained garbage in v2.2.29
mail-crypt: Re-encrypt when copying/moving mails and per-mailbox keys
are used. Otherwise the copied mails can't be opened.
dict-sql: Merging multiple UPDATEs to a single statement wasn't
actually working.
pigeonhole updated to 0.4.18
imapsieve plugin: Implemented the copy_source_after rule action. When this
is enabled for a mailbox rule, the specified Sieve script is executed for
the message in the source mailbox during a "COPY" event. This happens only
after the Sieve script that is executed for the corresponding message in the
destination mailbox finishes running successfully.
imapsieve plugin: Added non-standard Sieve environment items for the source
and destination mailbox.
multiscript: The execution of the discard script had an implicit "keep",
rather than an implicit "discard".
fts-tika: Fixed crash when parsing attachment without
Content-Disposition header. Broken by 2.2.28.
trash plugin was broken in 2.2.28
auth: When passdb/userdb lookups were done via auth-workers, too much
data was added to auth cache. This could have resulted in wrong
replies when using multiple passdbs/userdbs.
auth: passdb { skip & mechanisms } were ignored for the first passdb
oauth2: Various fixes, including fixes to crashes
dsync: Large Sieve scripts (or other large metadata) weren't always
synced.
Index rebuild (e.g. doveadm force-resync) set all mails as \Recent
imap-hibernate: %{userdb:*} wasn't expanded in mail_log_prefix
doveadm: Exit codes weren't preserved when proxying commands via
doveadm-server. Almost all errors used exit code 75 (tempfail).
ACLs weren't applied to not-yet-existing autocreated mailboxes.
Fixed a potential crash when parsing a broken message header.
cassandra: Fallback consistency settings weren't working correctly.
doveadm director status <user>: "Initial config" was always empty

auth: Support OAUTHBEARER and XOAUTH2 mechanisms. Also support them
in lib-dsasl for client side.

client_check_command_hangs

doveadm-server: Fix leaks and other problems when process is reused
for multiple requests (service_count != 1)
sdbox: Fix assert-crash on mailbox create race

was used. especially %{storage_id} was broken.
imapsieve plugin: Fixed assert failure occurring when used with virtual
mailboxes.
doveadm sieve plugin: Fixed crash when setting Sieve script via attribute's
string value.
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.

- 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.
- 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.

- and more...
- 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.
- lazy-expunge: Fixed a crash when copying failed. Various other fixes.
- fts-lucene: Fixed crash on index rescan.
- dict-ldap: Various fixes
- dict-sql: NULL values crashed. Now they're treated as "not found".

use both auth_stats=yes and mail stats plugin.

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.
- pigeonhole updated to 0.4.14
- extprograms plugin: Fixed epoll() panic caused by closing the output
FD before the output stream.
- Made sure that the local part of a mail address is encoded properly
using quoted string syntax when it is not a dot-atom.

doveadm-server was broken.

- 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.
- 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.

caught actual hangs or otherwise unwanted behavior towards IMAP

configuration options.
- Sieve mime extension: Fixed the header :mime :anychild test to work properly
outside a foreverypart loop.

single director server.

- implemented the Sieve mime and foreverypart extensions (RFC 5703).
+ sieve body extension: Properly implemented the `:text' body
transform. It now extracts text for HTML message parts.

set modifier. An empty string yielded an empty string rather than "0".

allocation in the sieve command implementations.

didn't support NOTIFY.
- imap: After SETMETADATA was used, various commands (especially FETCH)
could have started hanging when their output was large.

process to forget them and log errors about unknown sessions when
they were updated later.

multiple recipients and fts_autoindex=yes.

lmtp_rcpt_check_quota=yes

director ring sockets, causing it to break in existing installations.
- sdbox: When copying a mail in alt storage, place the destination to
alt storage as well.
- auth: Don't crash if master user login is attempted without
any configured master=yes passdbs
- Parsing UTF-8 text for mails could have caused broken results
sometimes if buffering was split in the middle of a UTF-8 character.
This affected at least searching messages.
- String sanitization for some logged output wasn't done properly:
UTF-8 text could have been truncated wrongly or the truncation may
not have happened at all.
- fts-lucene: Lookups from virtual mailbox consisting of over 32
physical mailboxes could have caused crashes.
- fixed several race conditions with dovecot.index.cache handling that
may have caused unnecessary "cache is corrupted" errors.
