"Debian has added more security-oriented features to the newest version of its OS. Besides the regular Debian security support for the full archive, lenny introduces pro-active security features to pre-emptively reduce the chance of vulnerabilities. For example, the Debian Installer now applies any security updates before the first boot, several security-critical packages have been built with GCC hardening features, and the standard system contains fewer setuid root binaries and fewer open ports.
"On the server-side, new features include support for PostgreSQL 8.3.5, MySQL 5.1.30 and 5.0.51a, GNU Compiler Collection 4.3.2, Samba 3.2.5, Python 2.5.2 and 2.4.6, Perl 5.10.0, PHP 5.2.6, Asterisk 1.4.21.2, Nagios 3.06 and the Xen Hypervisor 3.2.1."
