I noticed some behavior that seems to be new, and it doesn't seem intentional. Before, when I clicked a non-highlighted square as destination, I got a popup to ask whether I was sure I wanted to play an illegal move, and when I confirmed that, it submitted the move. I do this often to test whether the error messages my generic code gives are working and understandable. Now, however, when I want to step into check with my King, it complains "is not a valid square", instead of the expected "This exposes your royal to check". Turns out the move that is submitted was "K c4-", i.e. the click on c3 (where I would be in check) had been ignored completely. (Except that it cause submitting of the move.)
