The Kokua viewer team is following in the footsteps of Firestorm developers and creating a new branch of the viewer software just for OpenSim.
Because of Linden Lab licensing issues, there are some features that viewers can only offer to Second Life users. In addition, there are some features like variable-sized regions that are only available in OpenSim and its close relatives, AuroraSim and WhiteCoreSim.
There won’t be any immediate impact from the change, however.
“For now, both the Second Life and OpenSim viewers operate in both grid environments,” said the Kokua announcement.
