Thanks for the release. I just upgraded and error messages are really nice. One bit I might be missing is that Python 3.10 added suggestions for AttributeError and NameError. It seems the suggestions are not stored in the exception object but calculated when Error is displayed. There is a note that that this won't work with IPython but it will be good to check if it's feasible.
