[An on-line version of this announcement will be available at http://www.postfix.org/announcements/postfix-3.4.3.html]
Postfix stable release 3.4.3 is available.
One of the Postfix 3.4.2 changes (LINUX5) was missing. For your convenience, the remainder of this text repeats the content of the Postfix 3.4.2 announcement.
DANE trust anchor file support was broken after the Postfix 3.4 TLS library overhaul. Fix by intrigeri.
LINUX5 is supported, based on sanity checks with a Rawhide prerelease.
Fixes for two null pointer reads in warnings for errors that never happen (in code from 7 and 18 years ago, respectively).
The plan is to maintain zero code difference between the stable release and the development release, until there have been no bug-of-the-week patches for much more than several weeks.
You can find the updated Postfix source code at the mirrors listed at http://www.postfix.org/.
