GNOME 2.22 was released on schedule on 13th March 2008. The list of new features are here. The speed of announcement by the GNOME hacker, this blog entry literally is yesterday news. It is amazing how the community managed to pull it all together even when there was some doubts about the viability of the release back in December 2007. Well Done to All there!
GNOME 2.22 release on OpenSolaris is not official due until Nevada build 88 according to the current plan. The preview of that is actually in vermillion devel 86 if you know what I am talking about.
Update: Damien just sent out and email saying vermillion devel 86 is DOA . Workaround is on the way, but given many are on holidays over Paddy day and Easter. The wokaround is unlikely to be available until the holidays is over. So better off waiting for Vermillion 87.
Update 2: Good man, Damien has spent beyond his holidays and uploaded the HAL packages to make sure that vermillion devel 86 is working on download. Extra steps in the instruction is here. Kudos to Damien!
