Kokua OpenSim Viewer Released

KokuaOS- is an initial release. Gavin Hird (macOS) is the lead developer for KokuaOS. This viewer is for OpenSim grids and is branched off at Kokua version 4.0.2. The default grid is set to 3rd Rock Grid as their support for Kokua and Imprudence extends back a number of years with the Hoagie sim contribution. While the ability to logon to SecondLife is present, Jelly Doll support is not, and we expect more wandering away from SecondLife as new features such as Bento Joints, and server infrastructure removal take place.

There are no automatic up dates with KokuaOS. If you want it, download and install on your schedule.
