+
+#### _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)
+
+- `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 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)
- Added parsing support for unparenthesized tuples and yield expressions in annotated
assignments (#1835)
-- use lowercase hex strings (#1692)
-
- added `--extend-exclude` argument (PR #2005)

+- PR #2053: Black no longer relies on typed-ast for Python 3.8 and higher
+
+- PR #2053: Python 2 support is now optional, install with
+ `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)
+
#### _Packaging_
