+ (#2174)

+## 21.5b0
+

+
+- Fix crash when atypical whitespace is cleaned out of dostrings (#2120)
+
+- Reflect the `--skip-magic-trailing-comma` and `--experimental-string-processing` flags
+ in the name of the cache file. Without this fix, changes in these flags would not take
+ effect if the cache had already been populated. (#2131)
+
+- Don't remove necessary parentheses from assignment expression containing assert /
+ return statements. (#2143)
+
+### _Packaging_
+

+
+### _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)

docstring quotes (#1637)

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

+ to split lines (#1824)
+
+- fixed a crash when PWD=/ on POSIX (#1631)
+
+- fixed "I/O operation on closed file" when using --diff (#1664)
+

+ (#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

+ `python3 -m pip install black[python2]` to maintain support.
+
+- Exclude `venv` directory by default (#1683)
+
+- Fixed "Black produced code that is not equivalent to the source" when formatting
+ Python 2 docstrings (#2037)
