Nightly builds

The next version of Oolite is being developed, with frequent changes. Nightly builds of the latest source are available for testers.

Warning: these builds may at any time contain serious bugs, prototype features, and other unstable code. We do not recommend these for regular play, and you should take backups of your saved games before using them.

If you would like to try out the latest code, and give us feedback on the new features, then you can find the links to the nightly builds on the Oolite forum.
