OpenBSD 5.3 introduces stable SMTPD
The OpenBSD team has released OpenBSD 5.3, the latest version of the UNIX-like operating system. This version brings a number of new drivers and expanded hardware support, as well as improvements to the distribution's networking stack. The OpenSMTPD code is now considered stable.
OpenSMTPD "is now considered stable and suitable for use in production" by the developers. OpenBSD 5.3 includes version 5.3 of the daemon, which has received a number of new features including an improved logging format and better memory handling, and generally performs faster both when sending and receiving messages.
OpenBSD 5.3 introduces the npppd daemon for the L2TP, L2TP/IPsec, PPTP and PPPoE protocols. Security improvements include the use of position-independent executables by default on a number of architectures including amd64, as well as improved stack smashing protection in GCC. As usual, a large number of software components have been updated. A detailed list of all updates and improvements since OpenBSD 5.2 is available in the change log.
OpenBSD 5.3, code-named "Blade Swimmer", is available for download from the OpenBSD mirrors; it is possible to order the release on physical CDs to support the project. Users can also donate to the OpenBSD Foundation.
