Hello Dovecot users,
Here is the final 0.4.7 release. No changes were committed since the
last release candidate.
Changelog v0.4.7:
* editheader extension: Made protection against addition and deletion of
headers configurable separately. Also, the `Received' and
`Auto-Submitted' headers are no longer protected against addition by
default.
* Turned message envelope address parse errors into warnings.
* The interpreter now accepts non-standard domain names, e.g.
containing '_'.
+ Implemented the Sieve index extension (RFC 5260).
+ Implemented support for the mboxmetadata and servermetadata extensions
(RFC 5490).
+ Implemented new sieve commands for the doveadm command line utility.
These commands are currently limited to ManageSieve operations, but
the other current sieve tools will be migrated to doveadm in the near
future as well.
+ Added more debug output about binary up-to-date checking.
+ Added script metadata to binary dump output.
- Fixed Sieve script binary up-to-date checking by normalizing the
script location.
- The Sieve interpreter now flushes the duplicate database during start
phase of result execution rather than commit phase. This makes sure
locks on the duplicate database are released as soon as possible,
preventing contention.
- Performed a few optimizations in the lexical scanner of the language.
- Fixed bug in `:matches' match-type that made a pattern without
wildcards match as if there were a '*' at the beginning.
- Fixed crash in validation of the string parameter of the comparator
tag.
- extprograms extension: Made sure supplemental group privileges are
also dropped. This was a problem reported by Debian lintian.
- Fixed bug in handling of binary errors for action side-effects and
message overrides.
- file script storage: Restructured storage initialization to address
backwards compatibility issues.
- dict script storage: Fixed small memory allocation bug.
The release is available as follows:

Hi all,
Today I can finally announce that Dovecot Oy company has merged with Open-Xchange AG. This helps us to get more Dovecot developers, support people and so on. Most importantly, eventually it should allow me to get back to doing what I like the most: Designing new and interesting stuff for Dovecot and perfecting the old stuff :) OX is a great match to Dovecot going forward. They also really like open source and share our plans for the future. Nothing big will change as a result of this merger: Dovecot will stay Dovecot with its own name and release schedules. We're not going to force OX and Dovecot to be the same product, other than having a somewhat deeper integration between them.
Here are the press release links about it:

Hello Dovecot users,
The rc2 release had a couple of new, rather small, but very annoying
bugs. First of all, the path for a file storage wasn't actually
normalized, due to a stupid last-minute change before the release. This
caused the personal script to be skipped with a warning when there were
e.g. duplicate slashes in the path.
Second, due to recent changes, the file storage would complain with a
temporary error if the directory where the active script symlink would
be located was missing.
Changelog v0.4.7 (unchanged):
* editheader extension: Made protection against addition and deletion of
headers configurable separately. Also, the `Received' and
`Auto-Submitted' headers are no longer protected against addition by
default.
* Turned message envelope address parse errors into warnings.
* The interpreter now accepts non-standard domain names, e.g.
containing '_'.

Hello Dovecot users,
The rc1 release showed a few problems with the up-to-date checking of
on-disk binary files. The binary files contain some metadata about the
script these were compiled from. If this doesn't match the current
script anymore, the script is recompiled. One of these metadata items is
the script location. However, this location wasn't normalized, so when
the binary would be compiled with sievec it depended on the path
provided at the command line.
When dumping a script binary, the metadata is now printed as well. Also,
I added more debug log lines about up-to-date checking.
I improved backwards compatibility for the file script storage a bit
relative to the last version. It now properly recognizes a regular file
at the symlink path, even when the storage path itself doesn't exist.
Changelog v0.4.7 (updated):
* editheader extension: Made protection against addition and deletion of
headers configurable separately. Also, the `Received' and
`Auto-Submitted' headers are no longer protected against addition by
default.
* Turned message envelope address parse errors into warnings.
* The interpreter now accepts non-standard domain names, e.g.
containing '_'.

A few fixes and some imapc improvements since the release candidate.
* dbox: Resyncing (e.g. doveadm force-resync) no longer deletes
dovecot.index.cache file. The cache file was rarely the problem
so this just caused unnecessary slowness.
* Mailbox name limits changed during mailbox creation: Each part of
a hierarchical name (e.g. "x" or "y" in "x/y") can now be up to 255
chars long (instead of 200). This also reduces the max number of
hierarchical levels to 16 (instead of 20) to keep the maximum name
length 4096 (a common PATH_MAX limit). The 255 char limit is
hopefully large enough for migrations from all existing systems.
It's also the limit on many filesystems.
+ director: Added director_consistent_hashing setting to enable
consistent hashing (instead of the mostly-random MD5 hashing).
This causes fewer user moves between backends when backend counts
are changed, which may improve performance (mainly due to caching).
+ director: Added support for "tags", which allows one director ring
to serve multiple backend clusters with different sets of users.
+ LMTP server: Added lmtp_user_concurrency_limit setting to limit how
many LMTP deliveries can be done concurrently for a single user.
+ LMTP server: Added support for STARTTLS command.
+ If logging data is generated faster than it can be written, log a
warning about it and show information about it in log process's
process title in ps output. Also don't allow a single service to
flood too long at the cost of delaying other services' logging.
+ stats: Added support for getting global statistics.
+ stats: Use the same session IDs as the rest of Dovecot.
+ stats: Plugins can now create their own statistics fields
+ doveadm server: Non-mail related commands can now also be used
via doveadm server (TCP socket).
+ doveadm proxying: passdb lookup can now override doveadm_port and
change the username.
+ doveadm: Search query supports now "oldestonly" parameter to stop
immediately on the first non-match. This can be used to optimize:
doveadm expunge mailbox Trash savedbefore 30d oldestonly
+ doveadm: Added "save" command to directly save mails to specified
mailbox (bypassing Sieve).
+ doveadm fetch: Added body.snippet field, which returns the first
100 chars of a message without whitespace or HTML tags. The result
is stored into dovecot.index.cache, so it can be fetched efficiently.
+ dsync: Added -t <timestamp> parameter to sync only mails newer than
the given received-timestamp.
+ dsync: Added -F [-]<flag> parameter to sync only mails with[out] the
given flag/keyword.
+ dsync: Added -a <mailbox> parameter to specify the virtual mailbox
containing user's all mails. If this mailbox is already found to
contain the wanted mail (by its GUID), the message is copied from
there instead of being re-saved. (This isn't efficient enough yet
for incremental replication.)
+ dsync: -m parameter can now specify \Special-use names for mailboxes.
+ imapc: Added imapc_features=gmail-migration to help migrations from
GMail. See http://wiki2.dovecot.org/Migration/Gmail
+ imapc: Added imapc_features=search to support IMAP SEARCH command.
(Currently requires ESEARCH support from remote server.)
+ expire plugin: Added expire_cache=yes setting to cache most of the
database lookups in dovecot index files.
+ quota: If overquota-flag in userdb doesn't match the current quota
usage, execute a configured script.
+ redis dict: Added support for expiring keys (:expire_secs=n) and
specifying the database number (:db=n)
- 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.
Hello Dovecot users,
Last time I had a few stupid problems in the releases, so I'll follow
Timo's example and I release an RC first.
The highlights include the implementation of the index and metadata
extensions. Quite a few bugs are fixed as well.
Changelog v0.4.7:
* editheader extension: Made protection against addition and deletion of
headers configurable separately. Also, the `Received' and
`Auto-Submitted' headers are no longer protected against addition by
default.

* The interpreter now accepts non-standard domain names, e.g.
containing '_'.

+ Implemented support for the mboxmetadata and servermetadata extensions
(RFC 5490).
+ Implemented new sieve commands for the doveadm command line utility.

the other current sieve tools will be migrated to doveadm in the near
future as well.

also dropped. This was a problem reported by Debian lintian.

Looks like it's been a long time since v2.2.15. There have been a ton of changes since it was released though, so here's a release candidate first to find out if somebody can find any bugs before the final v2.2.16.
Unfortunately I haven't had time/energy to read Dovecot mailing list for a while now. I'm hoping this will change, but I don't really expect it to happen anytime soon. On the positive side for Dovecot, it's now becoming used in more and more multi-million user installations, which brings all kinds of nice new improvements.
The largest changes since v2.2.15:
* dbox: Resyncing (e.g. doveadm force-resync) no longer deletes
dovecot.index.cache file. The cache file was rarely the problem
so this just caused unnecessary slowness.
