Hello Dovecot users,
Here is the definitive 0.4.9 release. Only a few minor fixes were done
since RC1.
Changelog v0.4.9:
* Properly implemented checking of ABI version for Sieve interpreter
plugins, much like Dovecot itself does for plugins. This will prevent
plugin ABI mismatches.
+ Implemented a vnd.dovecot.environment extension. This builds upon the
standard environment extension and adds a few more environment items,
such as username and default mailbox. It also creates a variables
namespace so that environment items can be accessed directly. I am
still thinking about more environment items that can be added.
+ Sieve extprograms plugin: Made line endings of the input passed to the
external programs configurable. This can be configured separately for
each of the three extensions.
+ ManageSieve: Implemented proxy XCLIENT support. This allows the proxy
to pass client information to the back-end.
- ManageSieve: Fixed an assert failure occurring when a client
disconnects during the GETSCRIPT command.
- doveadm sieve plugin: Fixed incorrect initialization of mail user.
This caused a few memory leaks.
- sieve-filter command line tool: Fixed handling of failure-related
implicit keep when there is an explicit default destination folder.
This caused message duplication.
- lib-sieve: Fixed bug in RFC5322 header folding. Words longer than the
optimal line length caused empty lines in the output, which would
break the resulting message header. This surfaced in References:
headers with very long message IDs.
The release is available as follows:

Refer to http://pigeonhole.dovecot.org and the Dovecot v2.x wiki for
more information. Have fun testing this new release and don't hesitate
to notify me when there are any problems.

* pop3_deleted_flag has been broken since v2.2.10. Using it would
cause buffer overflows, which could be exploitable. However, this
bug would have become visible quite soon after users had deleted
some POP3 mails, because the pop3 processes would have started
crashing all the time even in normal use.
* "doveadm director flush" command has a changed meaning now:
It safely moves users to their wanted backends, instead of simply
forgetting the mapping entirely and leaving the existing connections
untouched. Use -F parameter to get the original unsafe behavior.
+ Added imap-hibernate processes (see imap_hibernate_timeout setting).
IDLEing IMAP connections can be hibernated, which saves memory.
+ Optimized tracking mailboxes' vsizes (= sum of all messages' sizes).
If mailbox_list_index=yes, it's also stored in there. This makes it
very efficient to look up vsizes for all mailboxes.
+ Added a quota "count" backend, which uses the mailbox vsizes to get
the current quota usage. It requires using the new quota_vsizes=yes
setting, which tracks the messages' "virtual sizes" rather than
"physical sizes". Their distiction is minor and mostly irrelevant
nowadays (if mail sizes should be counted with LF or CRLF newlines).
+ "doveadm director up/down" commands added. The monitoring script
should be using these commands instead of changing the vhost count.
This allows admin to manually disable a server by changing the vhost
count to 0 without the monitoring script changing it back.
+ Added support for HAProxy protocol: http://wiki2.dovecot.org/HAProxy
+ Added push-notification plugin framework, which can be used to
easily implement push notifications to various backends. Implemented
"ox" backend for notifying Open-Xchange via HTTP/json.
+ imap_logout_format supports more variables now, e.g. number of
deleted messages.
+ pop3: Added pop3_delete_type setting (related to pop3_deleted_flag).
+ plugin { fts_enforced=yes } setting now fails body searches unless
it can be done via the full text search engine.
+ Added %{passdb:*} and %{userdb:*} variables to various places
+ auth: Added ":protected" suffix for passdb and userdb fields. If
used, the field doesn't overwrite an existing field.
+ IMAP/POP3 proxy: If a backend server dies, avoid client reconnection
spikes by slowly disconnecting clients over time. This is enabled by
setting login_proxy_max_disconnect_delay=secs passdb extra field.
+ imap: Added new read-only METADATA entries: /private/specialuse,
/shared/comment, /shared/admin
+ imap: If client disconnects in the middle of a command, log how long
the command had been running.
- mdbox: Rebuilding could have caused message's reference count to
overflow the 16bit number in some situations, causing problems when
trying to expunge the duplicates.
- Various search fixes (fts, solr, tika, lib-charset, indexer)
- Various virtual plugin fixes
- Various fixes and optimizations to dsync, imapc and pop3-migration
- imap: Various RFC compliancy and crash fixes to NOTIFY
