I did some initial tests (and a test compile) with the new Unity 2022.2 - so far it seems to work and is compatible without any errors.
The only thing I ran into is related to the sorting order of canvases created for UI layers. Seems like setting their sorting order on creation is ignored in 2022.2, but I already implemented a workaround for that.
Expect an update sometime next week :)
Please let me know if you run into any issues related to Unity 2022.2 in your projects.
