[dependabot]

Bumps black from 20.8b1 to 21.4b0.

Release notes

Sourced from black's releases.

21.4b0

Black

• Fixed a rare but annoying formatting instability created by the combination of optional trailing commas inserted by Black and optional parentheses looking at pre-existing "magic" trailing commas. This fixes issue #1629 and all of its many many duplicates. (#2126)

• Black now processes one-line docstrings by stripping leading and trailing spaces, and adding a padding space when needed to break up """". (#1740)

• Black now cleans up leading non-breaking spaces in comments (#2092)

• Black now respects --skip-string-normalization when normalizing multiline docstring quotes (#1637)

• Black no longer removes all empty lines between non-function code and decorators when formatting typing stubs. Now Black enforces a single empty line. (#1646)

• Black no longer adds an incorrect space after a parenthesized assignment expression in if/while statements (#1655)

• Added --skip-magic-trailing-comma / -C to avoid using trailing commas as a reason to split lines (#1824)

• fixed a crash when PWD=/ on POSIX (#1631)

• fixed "I/O operation on closed file" when using --diff (#1664)

• Prevent coloured diff output being interleaved with multiple files (#1673)

• Added support for PEP 614 relaxed decorator syntax on python 3.9 (#1711)

• Added parsing support for unparenthesized tuples and yield expressions in annotated assignments (#1835)

• use lowercase hex strings (#1692)

• added --extend-exclude argument (PR #2005)

• speed up caching by avoiding pathlib (#1950)

• --diff correctly indicates when a file doesn't end in a newline (#1662)

• Added --stdin-filename argument to allow stdin to respect --force-exclude rules (#1780)

• Lines ending with fmt: skip will now be not formatted (#1800)

• PR #2053: Black no longer relies on typed-ast for Python 3.8 and higher

... (truncated)

Looks like black is up-to-date now, so this is no longer needed.
