New point version.

[Douglas R. Reno]

v2.3.4 2018-11-23  Timo Sirainen <tss@iki.fi>

	* 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.
	  See https://wiki2.dovecot.org/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.
