On September 5, 2009, the third stable release of Debian GNU / Linux codenamed "Lenny" was released, which traditionally includes many fixes, more about which can be found on
this page.
It should be noted that updates affect important packages such as
apache2 ,
dhcp3 ,
bind9 ,
mysql-dfsg and others. ISO images will get on the mirrors in the coming days, while you can upgrade with apt now.
I recommend system administrators to use the
debian-security-announce mailing list, so you will always be up to date with the latest updates.
