When running code on Python 3.8 that previous was running 3.3, I ran into the issue that the default value for the digestmod parameter of hmac.new() has been changed to backwards-incompatible value.

I generally would have expected such a break to show up in https://docs.python.org/3/whatsnew/3.8.html#api-and-feature-removals. If not there, somewhere on the 3.8 changelog page.

The removal does seem mentioned under the function section, but I wonder if it should be also noted in the changelog

[tiran]

It's documented in the 3.4 changelog, https://docs.python.org/3/whatsnew/3.4.html#hmac

I would not object to add a note to the "porting to 3.8" section.
