- note advice for test runners in abstract
- add explicit sections for test runner and
interactive shell guidance
- simplify the warning category descriptions
by moving the test runner details to their
new section
- make it clear FutureWarning is gaining a
second use case, while also keeping its old
one
- note that IPython already follows the new
guidance for interactive shells (and use
their approach as an example)
- reword the advice for library and framework
authors wanting seeking noisier compatibility
warnings on earlier Python versions
