Finally some more information on the upcoming OpenSolaris release, which also seem to have changed name from 2010.03 to 2010.05.
There is a new draft of the "Whats new" document for the OpenSolaris release available online. It lists the major new features thats available with the upcoming release. Hopefully it will be released in the next few weeks.
Update: The document was removed but it's now available again. This is basically the same document as the old 2010.03 version, with some minor modifications.
