-- numeric literals are now formatted by _Black_ (#452, #461, #464, #469):
-
- - numeric literals are normalized to include `_` separators on Python 3.6+ code
-
- - added `--skip-numeric-underscore-normalization` to disable the above behavior and
- leave numeric underscores as they were in the input
-

-- adjacent string literals are now correctly split into multiple lines (#463)
-
