HISTORY

	mailbox_transport_maps, mailbox_command_maps or
	fallback_transport_maps, the local delivery agent did not
	log the problem before deferring mail, and produced no defer
	logfile record. Files: local/mailbox.c, local/unknown.c.

20120130

	Bugfix (introduced: Postfix 2.3): the trace service did not
	distinguish between DSN SUCCESS notifications for a non-bounce
	or a bounce message, and replied to mail from <>. This code
	pre-dates DSN support and should have been updated when it
	was re-purposed to handle DSN SUCCESS notifications.  Problem
	reported by Sabahattin Gucukoglu.  File:
	bounce/bounce_trace_service.c.

20120202

	Bugfix (introduced: Postfix 2.3): the "change header" milter
	request could replace the wrong header. A long header name
	could match a shorter one, because a length check was done
	on the wrong string.  Reported by Vladimir Vassiliev.  File:
	cleanup/cleanup_milter.c.

20120214

	Bugfix (introduced: Postfix 2.4): extraneous null assignment
	caused core dump when postlog emitted the "usage" message.
	Reported by Kant (fnord.hammer). File: postlog/postlog.c.

20120401

	Bitrot: shut up useless warnings about Cyrus SASL call-back
	function pointer type mis-matches. Files: xsasl/xsasl_cyrus.h,
	xsasl/xsasl_cyrus_server.c, xsasl/xsasl_client.c.

20120422

	Bit-rot: OpenSSL 1.0.1 introduces new protocols. Update the
	known TLS protocol list so that protocols can be turned off
	selectively to work around implementation bugs.  Based on
	a patch by Victor Duchovni.  Files: proto/TLS_README.html,
	proto/postconf.proto, tls/tls.h, tls/tls_misc.c, tls/tls_client.c,
	tls/tls_server.c.

20120425

	Workaround: bugs in 10-year old gcc versions break compilation
	with #ifdef inside a macro invocation (NOT: definition).
	Files: tls/tls.h, tls/tls_client.c, tls/tls_server.c.

20120517

	Workaround: to avoid crashes when the OpenSSL library is
	updated without "postfix reload", the Postfix TLS session
	cache ID now includes the OpenSSL library version number.
	Note: this problem cannot be fixed in tlsmgr(8). Code by
	Victor Duchovni. Files: tls/tls_server.c, tls_client.c.

20120520

	Bugfix (introduced Postfix 2.4): the event_drain() function
	was comparing bitmasks incorrectly causing the program to
	always wait for the full time limit. This error affected
	the unused postkick command, but only after s/fifo/unix/
	in master.cf.  File: util/events.c.

	Cleanup: laptop users have always been able to avoid
	unnecessary disk spin-up by doing s/fifo/unix/ in master.cf
	(this is currently not supported on Solaris systems).
	However, to make this work reliably, the "postqueue -f"
	command must wait until its requests have reached the pickup
	and qmgr servers before closing the UNIX-domain request
	sockets.  Files: postqueue/postqueue.c, postqueue/Makefile.in.
