+- Refactor `src/black/__init__.py` into many files (#2206)
+
+### Documentation
+
+- Replaced all remaining references to the
+ [`master`](https://github.com/psf/black/tree/main) branch with the
+ [`main`](https://github.com/psf/black/tree/main) branch. Some additional changes in
+ the source code were also made. (#2210)
+- Sigificantly reorganized the documentation to make much more sense. Check them out by
+ heading over to [the stable docs on RTD](https://black.readthedocs.io/en/stable/).
+ (#2174)
+
+## 21.5b0

+
+## 21.4b2

+- Fix crash if the user configuration directory is inaccessible. (#2158)
+
+- Clarify
+ [circumstances](https://github.com/psf/black/blob/master/docs/the_black_code_style.md#pragmatism)

+
+- 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_
+
+- Bump pathspec to >= 0.8.1 to solve invalid .gitignore exclusion handling

+## 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 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)

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

+
+- Exclude `venv` directory by default (#1683)
+
+- Fixed "Black produced code that is not equivalent to the source" when formatting
+ Python 2 docstrings (#2037)

+ Releases (#1743)
+
+## 20.8b1
+
+### _Packaging_
+
+- explicitly depend on Click 7.1.2 or newer as `Black` no longer works with versions
+ older than 7.0
+
+## 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 supports Python 3.8 code, e.g. star expressions in return statements
+ (#1121)

+ 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)
