Sun are officially launching OpenSolaris 2008.11 today... although as the name suggests, it was pretty much ready to go at the end of last month, and those in the know have been able to download it from both the community website and the distro website since then :) Join us at 1700 UTC today for a web chat with some of the people involved.
Glynn has written up a good summary of new features, which include GNOME 2.24, ZFS Time Slider, accessible install, and big improvements to plug'n'play printer support, automatic network configuration, and laptop suspend/resume. The number of additional packages available in the repositories has greatly improved since the 2008.05 release, and we now have various repos and a new process that will make contributing packages easier than ever.
Roman Strobl has produced a 12 minute screencast to show off some of the new bits, and Erwann Chénedé has a shorter one that focuses exclusively on Time Slider, which seems to have been generating a lot of interest.
Of course, 2008.11 still has all the usual Solaris goodness like ZFS, Zones and Dtrace built-in, with the Solaris Trusted Extensions now just a click away too, giving you access to one of the most secure desktops on the planet\*.
So why not give the LiveCD a spin? You can grab it via BitTorrent, or download the ISO directly from Sun (or alternatively, from the genunix mirror, or via FTP from LTH in Sweden).
\* Probably :) (OpenSolaris Trusted Extensions hasn't received Common Criteria Certfication yet, but the Solaris 10 version was most recently certified at EAL 4+. More information here.)
