Quest 5.5.1 is now available.
Various bugs have been fixed by me and Pertex. In particular, there were a couple of bugs with timers that meant they used to work unreliably, particularly when playing a game on the web. These have now been resolved, so if you were avoiding using timers, please try them again!
This release is now live for the web version of Quest, and you can also download the Windows version.
Please log any bugs you find on GitHub.
