Everything now seems to be stable and working in v2.2, so I can finally
move onto developing great new interesting features for v2.3. :)

My company has also launched a web shop where you can buy various
products. One of them is cheap access to Dovecot enterprise edition
repositories, which are basically same as regular Dovecot releases,
except they are kept patched with the latest important bugfixes. We
currently have releases for RHEL/CentOS 5 and 6, Debian Squeeze and
Ubuntu 12.04 LTS. By buying Dovecot-EE you'll also get a 30 day demo
license for object storages, if you want to try it out.

	* When creating home directories, the permissions are copied from the
	  parent directory if it has setgid-bit set. For full details, see
	* "doveadm auth" command was renamed to "doveadm auth test"
	* IMAP: ID command now advertises server name as Dovecot by default.
	  It was already trivial to guess this from command replies.
	* dovecot.index.cache files can be safely accessed only by v2.1.11+.
	  Older versions may think they're corrupted and delete them.
	* LDA/LMTP: If saving a mail brings user from under quota to over 
	  quota, allow it based on quota_grace setting (default: 10%
	  above quota limit).
	* pop3_lock_session=yes now uses a POP3-only dovecot-pop3-session.lock
	  file instead of actually locking the mailbox (and causing
	  IMAP/LDA/LMTP to wait for the POP3 session to close).
	* mail_shared_explicit_inbox setting's default switched to "no".
	* ssl_client_ca_dir setting replaced imapc_ssl_ca_dir and
	  pop3c_ssl_ca_dir settings.

	+ Implemented IMAP MOVE and BINARY extensions
	+ Implemented IMAP CATENATE, URLAUTH and URLAUTH=BINARY extensions
	  (by Stephan Bosch).
	+ Implemented IMAP NOTIFY extension. Requires mailbox_list_index=yes
	  to be enabled.
	+ Redesigned and rewritten dsync. The new design makes the syncing
	  faster, more reliable and more featureful. The new dsync protocol
	  isn't backwards compatible with old dsync versions (but is designed
	  to be forwards compatible with future versions).
	+ All mailbox formats now support per-user message flags for shared
	  mailboxes by using a private index. It can be enabled by adding
	  :INDEXPVT=<path> to mail location. This should be used instead of
	  :INDEX also for Maildir/mbox to improve performance.
	+ Improved mailbox list indexes. They should be usable now, although
	  still disabled by default.
	+ Added LAYOUT=index. The mailbox directories are created using their
	  GUIDs in the filesystem, while the actual GUID <-> name mapping
	  exists only in the index.
	+ LMTP proxy: Implemented XCLIENT extension for passing remote IP
	  address through proxy.
