We released OpenSim version 0.6.0 yesterday. It is SVN r7176. A Zip and binary are on the OSGrid web site amongst other places at http://osgrid.org. Click Instructions->Downloads to get to the download, or download from opensimulator.org from svn as usual.
We have now gotten to where we have about 60% of the features an average user would expect and the pace is still continuing at high speed. In addition, the forge (http://forge.opensimulator.org) has spawned 30 related projects including a search project that implements the beginnings of in-world search for grids.
We still need to implement the last 40 or so LSL functions and are now down to some vehicle physics issues that need attention.
OSGrid has finished the week with 6700 users, 750 regions and 1700 logins/day.
