An update from Spring 104.0.1-287-gf7b0fcc to Spring 104.0.1-901-g89b4773 is now live. Benchmarks sent in by users indicate that the framerate of the new engine is slightly more stable, and that performance is overall quite similar. The main advantages of the updated are the new features and fixes, with the possibility of more fixes to come.
The engine and AI devs have put in quite a bit of work into fixing the bugs found in local and multiplayer testing. However, we don't have the testing volume to find all the issues so please be patient and report any issues.
