OpenSim 0.4 Released!
The OpenSim team is happy to announce the first alpha release of OpenSim, version 0.4. This release focuses on stand-alone mode (with one or more regions). Some stuff works, a lot doesn't. If it breaks, you get to keep both pieces.
Stuff that works:
- standalone mode with one or more regions
- basic physics (no object collisions)
- persistence of users, prims, assets, and inventory via sqlite
- basic building, custom-texture uploads
- avatar editing
More advanced physics, in-world scripting, grid mode, and support for other database backends are not supported in this release, though they may work from time-to-time before crashing with an earth-shattering kaboom! All of these are under active development, and are being worked on for the 0.5 release.
Source distributions in both .tar.gz and .zip can be found at the OpenSim Downloads site.
