Less than 12 hours after its release, I have the pleasure to announce that the Debian experimental archive now carries packages for samba 3.6.0rc2 (please leave some time to autobuilders for packages for all architectures to be built, though). Instead of re-explaining how the Debian experimental archive is working, please allow me to point to a quite complete Wiki page about it: http://wiki.debian.org/DebianExperimental 3.6.* packages will remain in Debian experimental until the release of the final version of 3.6.0. Then, packages will be uploaded to Debian unstable, thus targeting the next Debian version (and indirectly flowing to Ubuntu, of course).
