Changelog

Sourced from black's changelog.

20.8b0

Black

• re-implemented support for explicit trailing commas: now it works consistently within any bracket pair, including nested structures (#1288 and duplicates)

• Black now reindents docstrings when reindenting code around it (#1053)

• Black now shows colored diffs (#1266)

• Black is now packaged using 'py3' tagged wheels (#1388)

• Black now supports Python 3.8 code, e.g. star expressions in return statements (#1121)

• Black no longer normalizes capital R-string prefixes as those have a community-accepted meaning (#1244)

• Black now uses exit code 2 when specified configuration file doesn't exit (#1361)

• Black now works on AWS Lambda (#1141)

• added --force-exclude argument (#1032)

• removed deprecated --py36 option (#1236)

• fixed --diff output when EOF is encountered (#526)

• fixed # fmt: off handling around decorators (#560)

• fixed unstable formatting with some # type: ignore comments (#1113)

• fixed invalid removal on organizing brackets followed by indexing (#1575)

• introduced black-primer, a CI tool that allows us to run regression tests against existing open source users of Black (#1402)

• introduced property-based fuzzing to our test suite based on Hypothesis and Hypothersmith (#1566)

• implemented experimental and disabled by default long string rewrapping (#1132), hidden under a --experimental-string-processing flag while it's being worked on; this is an undocumented and unsupported feature, you lose Internet points for depending on it (#1609)

Vim plugin

• prefer virtualenv packages over global packages (#1383)
