Actually, I found a regression. Looks like you also need to cancel any showwarning() function set by the user:

>>> import warnings
>>> warnings.showwarning = print
>>> with warnings.catch_warnings(record=True) as recording:
...     warnings.warn("hi")  # Unpatched did not call print()
hi <class 'UserWarning'> __main__ 2 None None
>>> recording  # Unpatched returned the warning here

Also, should the documentation of catch_warnings() be amended to say that there is no longer a custom showwarning() function? The recording mechanism is now an internal detail, and not accessible by calling showwarning().
