* The default postmaster_address is now "postmaster@<user domain or
server hostname>". If username contains the @domain part, that's
used. If not, then the server's hostname is used.
* "doveadm stats dump" now returns two decimals for the "avg" field.

+ Added push notification driver that uses a Lua script
+ Added new SQL, DNS and connection events.
+ Added "doveadm mailbox cache purge" command.
+ Added events API support for Lua scripts
+ doveadm force-resync -f parameter performs "index fsck" while opening
the index. This may be useful to fix some types of broken index files.
This may become the default behavior in a later version.
- director: Kicking a user crashes if login process is very slow
- pop3_no_flag_updates=no: Don't expunge DELEted and RETRed messages
unless QUIT is sent.
- auth: Fix crypt() segfault with glibc-2.28+
- imap: Running UID FILTER script with errors assert-crashes
- dsync, pop3-migration: POP3 UIDLs weren't added to
dovecot.index.cache while mails were saved.
- dict clients may have been using 100% CPU while waiting for dict
server to finish commands.
- doveadm user: Fixed user listing via HTTP API
- All levels of Cassandra log messages were logged as Dovecot errors.
- http/smtp client may have crashed after SSL handshake
- Lua auth converted strings that looked like numbers into numbers.
We had multiple servers with issues causing duplicate emails because of error "Panic: file lib-event.c: line 148 (event_unref): assertion failed: (event != current_global_event)". After updating Dovecot we haven't seen this errors for 4 days now. Hopefully this bug is fixed (took them a year).

To all users: make sure you recompile pigeonhole after you update dovecot (in case you use pigeonhole of course).

To the FreeBSD users: if you can't compile it with libiconv error, you must use the following configure.dovecot file:

export LDFLAGS="-L/usr/lib/dovecot -L/usr/local/lib"
./configure --prefix=/usr --sysconfdir=/etc --localstatedir=/var
This fix was added to the "build" script before but it looks like it's missing in the newest version.
