The Gentoo Release Engineering project is pleased to announce the much-delayed release of Gentoo Linux 2007.0, code named "Secret Sauce". This release met with several delays due to an abnormally high number of security vulnerabilities in large packages which had to be rebuilt using the newer, secure versions of the packages. There was also a complete resnapshot done about half-way through the release period due to the release taking so long and the packages becoming stale.
You can find out more information about the release in the official press release. To get the new release, grab it from http://www.gentoo.org/main/en/where.xml.
