The GCS Fuse bug that was fixed in XP7 yesterday has also been discovered in XP8, and is now fixed i version 8.1.1. We have also added a warning for event listeners that are outside main.js, as these will stop working when we switch to GraalJS in a future version of XP.

We hope this release will be helpful for you!
