- Black is now officially tested with Python 3.13 and provides Python 3.13
mypyc-compiled wheels. (4436) (4449)
- Black will issue an error when used with Python 3.12.5, due to an upstream memory
safety issue in Python 3.12.5 that can cause Black's AST safety checks to fail. Please
use Python 3.12.6 or Python 3.12.4 instead. (4447)
- Black no longer supports running with Python 3.8 (4452)

Stable style

- Fix crashes involving comments in parenthesised return types or `X | Y` style unions.
(4453)
- Fix skipping Jupyter cells with unknown `%%` magic (4462)

fn(*args: *tuple[*Ts, T]) -> None: pass`) (4440)

Caching

- Fix bug where the cache was shared between runs with and without `--unstable` (4466)

Packaging

- Upgrade version of mypyc used to 1.12 beta (4450) (4449)
- `blackd` now requires a newer version of aiohttp. (4451)

Output

- Added Python target version information on parse error (4378)
- Add information about Black version to internal error messages (4457)

24.8.0

Stable style

- Fix crash when ` fmt: off` is used before a closing parenthesis or bracket. (4363)

Packaging

- Packaging metadata updated: docs are explictly linked, the issue tracker is now also
linked. This improves the PyPI listing for Black. (4345)

Parser

multiline string (4339)
- Fix regression where Black failed to parse an escaped single quote inside an f-string
(4401)
- Fix bug with Black incorrectly parsing empty lines with a backslash (4343)
- Fix bugs with Black's tokenizer not handling `\{` inside f-strings very well (4422)

_Blackd_

- Fix blackd (and all extras installs) for docker container (4357)

24.4.2

This is a bugfix release to fix two regressions in the new f-string parser introduced in
24.4.1.

Parser

- Fix regression where certain complex f-strings failed to parse (4332)

Performance

- Fix bad performance on certain complex string literals (4331)

24.4.1

Highlights

- Add support for the new Python 3.12 f-string syntax introduced by PEP 701 (3822)

Stable style

- Fix crash involving indented dummy functions containing newlines (4318)

Parser

- Add support for type parameter defaults, a new syntactic feature added to Python 3.13
by PEP 696 (4327)

Integrations

- Github Action now works even when `git archive` is skipped (4313)

24.4.0

Stable style

- Fix unwanted crashes caused by AST equivalency check (4290)

Preview style

- `if` guards in `case` blocks are now wrapped in parentheses when the line is too long.
(4269)
- Stop moving multiline strings to a new line unless inside brackets (4289)

Integrations

- Add a new option `use_pyproject` to the GitHub Action `psf/black`. This will read the
Black version from `pyproject.toml`. (4294)

24.3.0

Highlights

This release is a milestone: it fixes Black's first CVE security vulnerability. If you
run Black on untrusted input, or if you habitually put thousands of leading tab
characters in your docstrings, you are strongly encouraged to upgrade immediately to fix
[CVE-2024-21503](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-21503).

This release also fixes a bug in Black's AST safety check that allowed Black to make
incorrect changes to certain f-strings that are valid in Python 3.12 and higher.

Stable style

- Don't move comments along with delimiters, which could cause crashes (4248)
- Strengthen AST safety check to catch more unsafe changes to strings. Previous versions
of Black would incorrectly format the contents of certain unusual f-strings containing
nested strings with the same quote type. Now, Black will crash on such strings until
support for the new f-string syntax is implemented. (4270)
- Fix a bug where line-ranges exceeding the last code line would not work as expected
(4273)

Performance

- Fix catastrophic performance on docstrings that contain large numbers of leading tab
characters. This fixes
[CVE-2024-21503](https://cve.mitre.org/cgi-bin/cvename.cgi?name=CVE-2024-21503).
(4278)

Documentation

- Note what happens when `--check` is used with `--quiet` (4236)

24.2.0

Stable style

- Fixed a bug where comments where mistakenly removed along with redundant parentheses
(4218)

Preview style

- Move the `hug_parens_with_braces_and_square_brackets` feature to the unstable style
due to an outstanding crash and proposed formatting tweaks (4198)
- Fixed a bug where base expressions caused inconsistent formatting of \*\* in tenary
expression (4154)
- Checking for newline before adding one on docstring that is almost at the line limit
(4185)
- Remove redundant parentheses in `case` statement `if` guards (4214).

Configuration

- Fix issue where _Black_ would ignore input files in the presence of symlinks (4222)
- _Black_ now ignores `pyproject.toml` that is missing a `tool.black` section when
discovering project root and configuration. Since _Black_ continues to use version
control as an indicator of project root, this is expected to primarily change behavior
for users in a monorepo setup (desirably). If you wish to preserve previous behavior,
simply add an empty `[tool.black]` to the previously discovered `pyproject.toml`
(4204)

Output

- Black will swallow any `SyntaxWarning`s or `DeprecationWarning`s produced by the `ast`
module when performing equivalence checks (4189)

Integrations

- Add a JSONSchema and provide a validate-pyproject entry-point (4181)

24.1.1

Bugfix release to fix a bug that made Black unusable on certain file systems with strict
limits on path length.

Preview style

- Consistently add trailing comma on typed parameters (4164)

Configuration

- Shorten the length of the name of the cache file to fix crashes on file systems that
do not support long paths (4176)

24.1.0

Highlights

This release introduces the new 2024 stable style (4106), stabilizing the following
changes:

- Add parentheses around `if`-`else` expressions (2278)
- Dummy class and function implementations consisting only of `...` are formatted more
compactly (3796)
- If an assignment statement is too long, we now prefer splitting on the right-hand side
(3368)
- Hex codes in Unicode escape sequences are now standardized to lowercase (2916)
- Allow empty first lines at the beginning of most blocks (3967, 4061)
- Add parentheses around long type annotations (3899)
- Enforce newline after module docstrings (3932, 4028)
- Fix incorrect magic trailing comma handling in return types (3916)
- Remove blank lines before class docstrings (3692)
- Wrap multiple context managers in parentheses if combined in a single `with` statement
(3489)
- Fix bug in line length calculations for power operations (3942)
- Add trailing commas to collection literals even if there's a comment after the last
entry (3393)
- When using `--skip-magic-trailing-comma` or `-C`, trailing commas are stripped from
subscript expressions with more than 1 element (3209)
- Add extra blank lines in stubs in a few cases (3564, 3862)
- Accept raw strings as docstrings (3947)
- Split long lines in case blocks (4024)
- Stop removing spaces from walrus operators within subscripts (3823)
- Fix incorrect formatting of certain async statements (3609)
- Allow combining ` fmt: skip` with other comments (3959)

There are already a few improvements in the `--preview` style, which are slated for the
2025 stable style. Try them out and
[share your feedback](https://github.com/psf/black/issues). In the past, the preview
style has included some features that we were not able to stabilize. This year, we're
adding a separate `--unstable` style for features with known problems. Now, the
`--preview` style only includes features that we actually expect to make it into next
year's stable style.

Stable style

Several bug fixes were made in features that are moved to the stable style in this
release:

- Fix comment handling when parenthesising conditional expressions (4134)
- Fix bug where spaces were not added around parenthesized walruses in subscripts,
unlike other binary operators (4109)
- Remove empty lines before docstrings in async functions (4132)
- Address a missing case in the change to allow empty lines at the beginning of all
blocks, except immediately before a docstring (4130)
- For stubs, fix logic to enforce empty line after nested classes with bodies (4141)

Preview style

- Add `--unstable` style, covering preview features that have known problems that would
block them from going into the stable style. Also add the `--enable-unstable-feature`
flag; for example, use
`--enable-unstable-feature hug_parens_with_braces_and_square_brackets` to apply this
preview feature throughout 2024, even if a later Black release downgrades the feature
to unstable (4096)
- Format module docstrings the same as class and function docstrings (4095)
- Fix crash when using a walrus in a dictionary (4155)
- Fix unnecessary parentheses when wrapping long dicts (4135)
- Stop normalizing spaces before ` fmt: skip` comments (4146)

Configuration

- Print warning when configuration in `pyproject.toml` contains an invalid key (4165)
- Fix symlink handling, properly ignoring symlinks that point outside of root (4161)
- Fix cache mtime logic that resulted in false positive cache hits (4128)
- Remove the long-deprecated `--experimental-string-processing` flag. This feature can
currently be enabled with `--preview --enable-unstable-feature string_processing`.
(4096)

Integrations

- Revert the change to run Black's pre-commit integration only on specific git hooks
(3940) for better compatibility with older versions of pre-commit (4137)

23.12.1

Packaging

- Fixed a bug that included dependencies from the `d` extra by default (4108)

23.12.0

Highlights

It's almost 2024, which means it's time for a new edition of _Black_'s stable style!
Together with this release, we'll put out an alpha release 24.1a1 showcasing the draft
2024 stable style, which we'll finalize in the January release. Please try it out and
[share your feedback](https://github.com/psf/black/issues/4042).

This release (23.12.0) will still produce the 2023 style. Most but not all of the
changes in `--preview` mode will be in the 2024 stable style.

Stable style

- Fix bug where ` fmt: off` automatically dedents when used with the `--line-ranges`
option, even when it is not within the specified line range. (4084)
- Fix feature detection for parenthesized context managers (4104)

Preview style

- Prefer more equal signs before a break when splitting chained assignments (4010)
- Standalone form feed characters at the module level are no longer removed (4021)

indented less (4012)
- Allow empty lines at the beginning of all blocks, except immediately before a
docstring (4060)
- Fix crash in preview mode when using a short `--line-length` (4086)
- Keep suites consisting of only an ellipsis on their own lines if they are not
functions or class definitions (4066) (4103)

Configuration

- `--line-ranges` now skips _Black_'s internal stability check in `--safe` mode. This
avoids a crash on rare inputs that have many unformatted same-content lines. (4034)

- Fix standalone comments inside complex blocks crashing Black (4016)
- Fix crash on formatting code like `await (a ** b)` (3994)
- No longer treat leading f-strings as docstrings. This matches Python's behaviour and
fixes a crash (4019)

Preview style

- Multiline dicts and lists that are the sole argument to a function are now indented
less (3964)
- Multiline unpacked dicts and lists as the sole argument to a function are now also
indented less (3992)
- In f-string debug expressions, quote types that are visible in the final string are
now preserved (4005)
- Fix a bug where long `case` blocks were not split into multiple lines. Also enable
general trailing comma rules on `case` blocks (4024)
- Keep requiring two empty lines between module-level docstring and first function or
class definition (4028)
- Add support for single-line format skip with other comments on the same line (3959)

Configuration

- Consistently apply force exclusion logic before resolving symlinks (4015)
- Fix a bug in the matching of absolute path names in `--include` (3976)

Performance

- Fix mypyc builds on arm64 on macOS (4017)

Integrations

- Black's pre-commit integration will now run only on git hooks appropriate for a code
formatter (3940)

- Treat raw triple-quoted strings as docstrings (3947)

Configuration

- Fix cache versioning logic when `BLACK_CACHE_DIR` is set (3937)

Parser

- Fix bug where attributes named `type` were not accepted inside `match` statements
(3950)

code (3933)
- Black will more consistently print stacktraces on internal errors in verbose mode
(3938)

Integrations

- The action output displayed in the job summary is now wrapped in Markdown (3914)

23.9.1

Due to various issues, the previous release (23.9.0) did not include compiled mypyc
wheels, which make Black significantly faster. These issues have now been fixed, and
this release should come with compiled wheels once again.

There will be no wheels for Python 3.12 due to a bug in mypyc. We will provide 3.12
wheels in a future release as soon as the mypyc bug is fixed.

Packaging

- Upgrade to mypy 1.5.1 (3864)

Performance

- Store raw tuples instead of NamedTuples in Black's cache, improving performance and
decreasing the size of the cache (3877)

23.9.0

Preview style

- More concise formatting for dummy implementations (3796)
- In stub files, add a blank line between a statement with a body (e.g an
`if sys.version_info > (3, x):`) and a function definition on the same level (3862)

_Blackd_

- Fix an issue in `blackd` with single character input (3558)

Integrations

- Black now has an
[official pre-commit mirror](https://github.com/psf/black-pre-commit-mirror). Swapping
`https://github.com/psf/black` to `https://github.com/psf/black-pre-commit-mirror` in
your `.pre-commit-config.yaml` will make Black about 2x faster (3828)
- The `.black.env` folder specified by `ENV_PATH` will now be removed on the completion
of the GitHub Action (3759)

23.7.0

Highlights

- Runtime support for Python 3.7 has been removed. Formatting 3.7 code will still be
supported until further notice (3765)

and the `pyproject.toml` found isn't in the current working directory (3719)
- _Black_ will now error if `exclude` and `extend-exclude` have invalid data types in
`pyproject.toml`, instead of silently doing the wrong thing (3764)

Packaging

- Upgrade mypyc from 0.991 to 1.3 (3697)
- Remove patching of Click that mitigated errors on Python 3.6 with `LANG=C` (3768)

Parser

- Add support for the new PEP 695 syntax in Python 3.12 (3703)

Performance

- Speed up _Black_ significantly when the cache is full (3751)
- Avoid importing `IPython` in a case where we wouldn't need it (3748)

Output

- Use aware UTC datetimes internally, avoids deprecation warning on Python 3.12 (3728)
- Change verbose logging to exactly mirror _Black_'s logic for source discovery (3749)

_Blackd_

- The `blackd` argument parser now shows the default values for options in their help
text (3712)

23.3.0

Highlights

This release fixes a longstanding confusing behavior in Black's GitHub action, where the
version of the action did not determine the version of Black being run (issue 3382). In
addition, there is a small bug fix around imports and a number of improvements to the
preview style.

Please try out the
[preview style](https://black.readthedocs.io/en/stable/the_black_code_style/future_style.html#preview-style)
with `black --preview` and tell us your feedback. All changes in the preview style are
expected to become part of Black's stable style in January 2024.

Stable style

- Import lines with ` fmt: skip` and ` fmt: off` no longer have an extra blank line
added when they are right after another import line (3610)

Preview style

- Add trailing commas to collection literals even if there's a comment after the last
entry (3393)
- `async def`, `async for`, and `async with` statements are now formatted consistently
compared to their non-async version. (3609)
- `with` statements that contain two context managers will be consistently wrapped in
parentheses (3589)
- Let string splitters respect [East Asian Width](https://www.unicode.org/reports/tr11/)
(3445)
- Now long string literals can be split after East Asian commas and periods (`、` U+3001
IDEOGRAPHIC COMMA, `。` U+3002 IDEOGRAPHIC FULL STOP, & `，` U+FF0C FULLWIDTH COMMA)
besides before spaces (3445)
- For stubs, enforce one blank line after a nested class with a body other than just
`...` (3564)
- Improve handling of multiline strings by changing line split behavior (1879)

Parser

- Added support for formatting files with invalid type comments (3594)

Integrations

- Update GitHub Action to use the version of Black equivalent to action's version if
version input is not specified (3543)
- Fix missing Python binary path in autoload script for vim (3508)

Documentation

- Document that only the most recent release is supported for security issues;
vulnerabilities should be reported through Tidelift (3612)

23.1.0

Highlights

This is the first release of 2023, and following our
[stability policy](https://black.readthedocs.io/en/stable/the_black_code_style/index.html#stability-policy),
it comes with a number of improvements to our stable style, including improvements to
empty line handling, removal of redundant parentheses in several contexts, and output
that highlights implicitly concatenated strings better.

There are also many changes to the preview style; try out `black --preview` and give us
feedback to help us set the stable style for next year.

In addition to style changes, Black now automatically infers the supported Python
versions from your `pyproject.toml` file, removing the need to set Black's target
versions separately.

Stable style

- Introduce the 2023 stable style, which incorporates most aspects of last year's
preview style (3418). Specific changes:
- Enforce empty lines before classes and functions with sticky leading comments

applied or there is a standalone comment between decorators (3470)
- Do not put the closing quotes in a docstring on a separate line, even if the line is
too long (3430)
- Long values in dict literals are now wrapped in parentheses; correspondingly
unnecessary parentheses around short values in dict literals are now removed; long
string lambda values are now wrapped in parentheses (3440)
- Fix two crashes in preview style involving edge cases with docstrings (3451)
- Exclude string type annotations from improved string processing; fix crash when the
return type annotation is stringified and spans across multiple lines (3462)
- Wrap multiple context managers in parentheses when targeting Python 3.9+ (3489)
- Fix several crashes in preview style with walrus operators used in `with` statements
or tuples (3473)
- Fix an invalid quote escaping bug in f-string expressions where it produced invalid
code. Implicitly concatenated f-strings with different quotes can now be merged or
quote-normalized by changing the quotes used in expressions. (3509)
- Fix crash on `await (yield)` when Black is compiled with mypyc (3533)

Configuration

- Black now tries to infer its `--target-version` from the project metadata specified in
`pyproject.toml` (3219)

Packaging

- Upgrade mypyc from `0.971` to `0.991` so mypycified _Black_ can be built on armv7
(3380)
- This also fixes some crashes while using compiled Black with a debug build of
 CPython
- Drop specific support for the `tomli` requirement on 3.11 alpha releases, working
around a bug that would cause the requirement not to be installed on any non-final
Python releases (3448)
- Black now depends on `packaging` version `22.0` or later. This is required for new
functionality that needs to parse part of the project metadata (3219)

Output

- Calling `black --help` multiple times will return the same help contents each time
(3516)
- Verbose logging now shows the values of `pyproject.toml` configuration variables
(3392)
- Fix false symlink detection messages in verbose output due to using an incorrect
relative path to the project root (3385)

Integrations

- Move 3.11 CI to normal flow now that all dependencies support 3.11 (3446)
- Docker: Add new `latest_prerelease` tag automation to follow latest black alpha
release on docker images (3465)

Documentation

- Expand `vim-plug` installation instructions to offer more explicit options (3468)

22.12.0

Preview style

- Enforce empty lines before classes and functions with sticky leading comments (3302)
- Reformat empty and whitespace-only files as either an empty file (if no newline is
present) or as a single newline character (if a newline is present) (3348)
- Implicitly concatenated strings used as function args are now wrapped inside
parentheses (3307)
- For assignment statements, prefer splitting the right hand side if the left hand side
fits on a single line (3368)
- Correctly handle trailing commas that are inside a line's leading non-nested parens
(3370)

Configuration

- Fix incorrectly applied `.gitignore` rules by considering the `.gitignore` location
and the relative path to the target file (3338)
- Fix incorrectly ignoring `.gitignore` presence when more than one source directory is
specified (3336)

Parser

- Parsing support has been added for walruses inside generator expression that are
passed as function args (for example,
`any(match := my_re.match(text) for text in texts)`) (3327).

Integrations

- Vim plugin: Optionally allow using the system installation of Black via
`let g:black_use_virtualenv = 0`(3309)

22.10.0

Highlights

- Runtime support for Python 3.6 has been removed. Formatting 3.6 code will still be
supported until further notice.

Stable style

- Fix a crash when ` fmt: on` is used on a different block level than ` fmt: off`
(3281)

Preview style

- Fix a crash when formatting some dicts with parenthesis-wrapped long string keys
(3262)

Configuration

- `.ipynb_checkpoints` directories are now excluded by default (3293)
- Add `--skip-source-first-line` / `-x` option to ignore the first line of source code
while formatting (3299)

Packaging

- Executables made with PyInstaller will no longer crash when formatting several files
at once on macOS. Native x86-64 executables for macOS are available once again.
(3275)
- Hatchling is now used as the build backend. This will not have any effect for users
who install Black with its wheels from PyPI. (3233)
- Faster compiled wheels are now available for CPython 3.11 (3276)

_Blackd_

- Windows style (CRLF) newlines will be preserved (3257).

Integrations

- Vim plugin: add flag (`g:black_preview`) to enable/disable the preview style (3246)
- Update GitHub Action to support formatting of Jupyter Notebook files via a `jupyter`
option (3282)
- Update GitHub Action to support use of version specifiers (e.g. `<23`) for Black
version (3265)

Update requests from 2.28.1 to 2.32.5.

Changelog

2.32.5

-------------------

**Bugfixes**

- The SSLContext caching feature originally introduced in 2.32.0 has created
a new class of issues in Requests that have had negative impact across a number
of use cases. The Requests team has decided to revert this feature as long term
maintenance of it is proving to be unsustainable in its current iteration.

**Deprecations**
- Added support for Python 3.14.
- Dropped support for Python 3.8 following its end of support.

2.32.4

-------------------

**Security**
- CVE-2024-47081 Fixed an issue where a maliciously crafted URL and trusted
environment will retrieve credentials for the wrong hostname/machine from a
netrc file.

**Improvements**
- Numerous documentation improvements

**Deprecations**
- Added support for pypy 3.11 for Linux and macOS.
- Dropped support for pypy 3.9 following its end of support.

2.32.3

-------------------

**Bugfixes**
- Fixed bug breaking the ability to specify custom SSLContexts in sub-classes of
HTTPAdapter. (6716)
- Fixed issue where Requests started failing to run on Python versions compiled
without the `ssl` module. (6724)

2.32.2

-------------------

**Deprecations**
- To provide a more stable migration for custom HTTPAdapters impacted
by the CVE changes in 2.32.0, we've renamed `_get_connection` to
a new public API, `get_connection_with_tls_context`. Existing custom
HTTPAdapters will need to migrate their code to use this new API.
`get_connection` is considered deprecated in all versions of Requests>=2.32.0.

A minimal (2-line) example has been provided in the linked PR to ease
migration, but we strongly urge users to evaluate if their custom adapter
is subject to the same issue described in CVE-2024-35195. (6710)

2.32.1

-------------------

**Bugfixes**
- Add missing test certs to the sdist distributed on PyPI.

2.32.0

-------------------

**Security**
- Fixed an issue where setting `verify=False` on the first request from a
Session will cause subsequent requests to the _same origin_ to also ignore
cert verification, regardless of the value of `verify`.
(https://github.com/psf/requests/security/advisories/GHSA-9wx4-h78v-vm56)

**Improvements**
- `verify=True` now reuses a global SSLContext which should improve
request time variance between first and subsequent requests. It should
also minimize certificate load time on Windows systems when using a Python
version built with OpenSSL 3.x. (6667)
- Requests now supports optional use of character detection
(`chardet` or `charset_normalizer`) when repackaged or vendored.
This enables `pip` and other projects to minimize their vendoring
surface area. The `Response.text()` and `apparent_encoding` APIs
will default to `utf-8` if neither library is present. (6702)

**Bugfixes**
- Fixed bug in length detection where emoji length was incorrectly
calculated in the request content-length. (6589)
- Fixed deserialization bug in JSONDecodeError. (6629)
- Fixed bug where an extra leading `/` (path separator) could lead
urllib3 to unnecessarily reparse the request URI. (6644)

**Deprecations**

- Requests has officially added support for CPython 3.12 (6503)
- Requests has officially added support for PyPy 3.9 and 3.10 (6641)
- Requests has officially dropped support for CPython 3.7 (6642)
- Requests has officially dropped support for PyPy 3.7 and 3.8 (6641)

**Documentation**
- Various typo fixes and doc improvements.

**Packaging**
- Requests has started adopting some modern packaging practices.
The source files for the projects (formerly `requests`) is now located
in `src/requests` in the Requests sdist. (6506)
- Starting in Requests 2.33.0, Requests will migrate to a PEP 517 build system
using `hatchling`. This should not impact the average user, but extremely old
versions of packaging utilities may have issues with the new packaging format.

2.31.0

-------------------

**Security**
- Versions of Requests between v2.3.0 and v2.30.0 are vulnerable to potential
forwarding of `Proxy-Authorization` headers to destination servers when
following HTTPS redirects.

When proxies are defined with user info (`https://user:passproxy:8080`), Requests
will construct a `Proxy-Authorization` header that is attached to the request to
authenticate with the proxy.

In cases where Requests receives a redirect response, it previously reattached
the `Proxy-Authorization` header incorrectly, resulting in the value being
sent through the tunneled connection to the destination server. Users who rely on
defining their proxy credentials in the URL are *strongly* encouraged to upgrade
to Requests 2.31.0+ to prevent unintentional leakage and rotate their proxy
credentials once the change has been fully deployed.

Users who do not use a proxy or do not supply their proxy credentials through
the user information portion of their proxy URL are not subject to this
vulnerability.

Full details can be read in our [Github Security Advisory](https://github.com/psf/requests/security/advisories/GHSA-j8r2-6x86-q33q)
and [CVE-2023-32681](https://nvd.nist.gov/vuln/detail/CVE-2023-32681).

2.30.0

-------------------

**Dependencies**
- ⚠️ Added support for urllib3 2.0. ⚠️

This may contain minor breaking changes so we advise careful testing and
reviewing https://urllib3.readthedocs.io/en/latest/v2-migration-guide.html
prior to upgrading.

Users who wish to stay on urllib3 1.x can pin to `urllib3<2`.

2.29.0

-------------------

**Improvements**

- Requests now defers chunked requests to the urllib3 implementation to improve
standardization. (6226)
- Requests relaxes header component requirements to support bytes/str subclasses. (6356)

2.28.2

-------------------

**Dependencies**

- Requests now supports charset\_normalizer 3.x. (6261)

**Bugfixes**

- Updated MissingSchema exception to suggest https scheme rather than http. (6188)
