[3.8] bpo-32528: Document the change in inheritance of asyncio.CancelledError (GH-21474) by miss-islington · Pull Request #21476 · python/cpython
GH-msg373510
[bpo-32528]()/GH-13528 changed asyncio.CancelledError such that it no longer inherits from concurrent.futures.CancelledError. As this affects existing code, specifically when catching the latter instead of the former in exception handling, it should be documented in the "What's new in 3.8?" document.
