[An on-line version of this announcement will be available at http://www.postfix.org/announcements/postfix-2.8.9.html]
Postfix stable release 2.8.9 is available. This contains fixes that are already part of Postfix 2.9 and 2.10.
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.
Core dump when postlog emitted the "usage" message, caused by an extraneous null assignment. Reported by Kant (fnord.hammer).
You can find the updated Postfix source code at the mirrors listed at http://www.postfix.org/.
