Subject: Note a performance improvement on PyPy in the release notes.
X-Git-Tag: v3.0.0~150

Note a performance improvement on PyPy in the release notes.

sys.exc_info() is very slow on pypy.  Commit
24c3d41748728cf4f3ea1509044b4abc7cea666e removed an unconditional
call to sys.exc_info when there is no error.  Performance on
demo/benchmark/benchmark.py went from 3k qps to 5k.
