The upcoming version 5.0 of Debian GNU/Linux, codenamed Lenny, provides for the first time not only image downloads for CD and DVD, but also for Blu-ray disks, along with live images.
The Debian 5.0 release missed its intended deadline of September and the project has been silent as yet about any news of an update. The latest guess from developers' circles is that "Lenny" will not be ready until June of 2009.
The Debian developers are preparing for the publication of Debian Lenny in September. The Release Team has just announced a complete freeze of all packages for next week.
