The grid is currently running on OpenSim 0.8.2 dev in order to benefit from a number of bug fixes and improvements to scripting functions, display name handling, inventory loading, attachment handling both scripted and unscripted, in addition to an important security patch.
The downside is that the OMC module is not running correctly, and OMC transactions are therefore not working. The issue has been reported to VirWOX support. Purchase transactions of free (0 OMC) items are still working.
