Parcel attributes are now working as they should, meaning that all media and audio settings you can configure via a viewer now both are set correctly and will persist over region restarts.
The cause of the faulty behavior was missing code in the PostgreSQL database server adapter, so any change made in the viewer was never written to the grid database.
Other noteworthy changes is that objects will no longer be auto returned as long as someone is sitting on them. This is consistent with the behavior in SecondLife.
A new OSSL scripting function; osGetPhysicsEngineName() as been added. This will return the physics engine and version the simulator for the region is running.
