Postfix stable release 3.4.0 is available. This release ends support
for legacy release Postfix 3.0.

The main changes are below. See the RELEASE_NOTES file for further

* Support for logging to file or stdout, instead of using syslog.
Logging to file solves a usability problem for MacOS users, and
eliminates multiple problems with systemd. Logging to stdout
eliminates a syslogd dependency when Postfix runs in a container.

* Postfix SMTP client support for multiple deliveries over the
same TLS-encrypted connection. This is primarily to improve
mail delivery performance for destinations that throttle clients
when they don't combine deliveries.

* SNI (server name indication) support in the Postfix SMTP server,
the Postfix SMTP client, and in the tlsproxy(8) daemon (both
server and client roles).

* Postfix SMTP server support for RFC 3030 CHUNKING (the BDAT
command) without BINARYMIME, in both smtpd(8) and postscreen(8).

* Support for TLS configuration files that contain multiple (key,
certificate, trust chain) instances. This was required to
implement server-side SNI table lookups, but it also eliminates
the need for separate cert/key files for RSA, DSA, Elliptic
Curve, and so on.

* Postfix 3.4 drops support for OpenSSL 1.0.1 (end-of-life was
December 31, 2016) and all earlier releases. Postfix 3.3 and
earlier still support older OpenSSL APIs.
