Yup, this update is great and glad to see it arrived and bugs fixed swiftly!
The editor compared to 4.2 is smoother to work with and has a bunch of great little UX additions, and the Transform constraint and Slider is ofc a game changer. Our team's upgrade has been smooth and in current state we've not experience any issues. Thanks!
The only noticeable negative for us has been showing/hiding skeletons in the editor, which seems slower now. Sometimes it can take 20 seconds for all the images to "reload". But after working in the editor for a while, it appears to become faster; to maximum 3 seconds. So in that case it's nothing major 👍️
We haven't seen or found any notes about changes there, so would be interesting to hear about it and if others experience the same.
