We have a new Release Candidate with a couple more fixes. https://github.com/getkirby/kirby/releases/tag/3.3.0-rc.3 It would be fantastic if you could help us test the release candidates for 3.3.0 as much as you can. Throw projects, plugins, themes or whatever at it and let us know if something unexpected breaks.
The release is planned for next Tuesday.
