Release Notes
psf/black
### [`v23.1.0`](https://togithub.com/psf/black/blob/HEAD/CHANGES.md#2310)
[Compare Source](https://togithub.com/psf/black/compare/22.12.0...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](https://togithub.com/psf/black/issues/3418)). Specific changes:
- Enforce empty lines before classes and functions with sticky leading comments
([#3302](https://togithub.com/psf/black/issues/3302)) (22.12.0)
- 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](https://togithub.com/psf/black/issues/3348))
(22.12.0)
- Implicitly concatenated strings used as function args are now wrapped inside
parentheses ([#3307](https://togithub.com/psf/black/issues/3307)) (22.12.0)
- Correctly handle trailing commas that are inside a line's leading non-nested parens
([#3370](https://togithub.com/psf/black/issues/3370)) (22.12.0)
- `--skip-string-normalization` / `-S` now prevents docstring prefixes from being
normalized as expected ([#3168](https://togithub.com/psf/black/issues/3168)) (since 22.8.0)
- When using `--skip-magic-trailing-comma` or `-C`, trailing commas are stripped from
subscript expressions with more than 1 element ([#3209](https://togithub.com/psf/black/issues/3209)) (22.8.0)
- Implicitly concatenated strings inside a list, set, or tuple are now wrapped inside
parentheses ([#3162](https://togithub.com/psf/black/issues/3162)) (22.8.0)
- Fix a string merging/split issue when a comment is present in the middle of
implicitly concatenated strings on its own line ([#3227](https://togithub.com/psf/black/issues/3227)) (22.8.0)
- Docstring quotes are no longer moved if it would violate the line length limit
([#3044](https://togithub.com/psf/black/issues/3044), [#3430](https://togithub.com/psf/black/issues/3430)) (22.6.0)
- Parentheses around return annotations are now managed ([#2990](https://togithub.com/psf/black/issues/2990)) (22.6.0)
- Remove unnecessary parentheses around awaited objects ([#2991](https://togithub.com/psf/black/issues/2991)) (22.6.0)
- Remove unnecessary parentheses in `with` statements ([#2926](https://togithub.com/psf/black/issues/2926)) (22.6.0)
- Remove trailing newlines after code block open ([#3035](https://togithub.com/psf/black/issues/3035)) (22.6.0)
- Code cell separators `#%%` are now standardised to `# %%` ([#2919](https://togithub.com/psf/black/issues/2919)) (22.3.0)
- Remove unnecessary parentheses from `except` statements ([#2939](https://togithub.com/psf/black/issues/2939)) (22.3.0)
- Remove unnecessary parentheses from tuple unpacking in `for` loops ([#2945](https://togithub.com/psf/black/issues/2945)) (22.3.0)
- Avoid magic-trailing-comma in single-element subscripts ([#2942](https://togithub.com/psf/black/issues/2942)) (22.3.0)
- Fix a crash when a colon line is marked between `# fmt: off` and `# fmt: on` ([#3439](https://togithub.com/psf/black/issues/3439))
##### Preview style
- Format hex codes in unicode escape sequences in string literals ([#2916](https://togithub.com/psf/black/issues/2916))
- Add parentheses around `if`-`else` expressions ([#2278](https://togithub.com/psf/black/issues/2278))
- Improve performance on large expressions that contain many strings ([#3467](https://togithub.com/psf/black/issues/3467))
- Fix a crash in preview style with assert + parenthesized string ([#3415](https://togithub.com/psf/black/issues/3415))
- Fix crashes in preview style with walrus operators used in function return annotations
and except clauses ([#3423](https://togithub.com/psf/black/issues/3423))
- Fix a crash in preview advanced string processing where mixed implicitly concatenated
regular and f-strings start with an empty span ([#3463](https://togithub.com/psf/black/issues/3463))
- Fix a crash in preview advanced string processing where a standalone comment is placed
before a dict's value ([#3469](https://togithub.com/psf/black/issues/3469))
- Fix an issue where extra empty lines are added when a decorator has `# fmt: skip`
applied or there is a standalone comment between decorators ([#3470](https://togithub.com/psf/black/issues/3470))
- Do not put the closing quotes in a docstring on a separate line, even if the line is
too long ([#3430](https://togithub.com/psf/black/issues/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](https://togithub.com/psf/black/issues/3440))
- Fix two crashes in preview style involving edge cases with docstrings ([#3451](https://togithub.com/psf/black/issues/3451))
- Exclude string type annotations from improved string processing; fix crash when the
return type annotation is stringified and spans across multiple lines ([#3462](https://togithub.com/psf/black/issues/3462))
- Wrap multiple context managers in parentheses when targeting Python 3.9+ ([#3489](https://togithub.com/psf/black/issues/3489))
- Fix several crashes in preview style with walrus operators used in `with` statements
or tuples ([#3473](https://togithub.com/psf/black/issues/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](https://togithub.com/psf/black/issues/3509))
- Fix crash on `await (yield)` when Black is compiled with mypyc ([#3533](https://togithub.com/psf/black/issues/3533))
##### Configuration
- Black now tries to infer its `--target-version` from the project metadata specified in
`pyproject.toml` ([#3219](https://togithub.com/psf/black/issues/3219))
##### Packaging
- Upgrade mypyc from `0.971` to `0.991` so mypycified *Black* can be built on armv7
([#3380](https://togithub.com/psf/black/issues/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](https://togithub.com/psf/black/issues/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](https://togithub.com/psf/black/issues/3219))
##### Output
- Calling `black --help` multiple times will return the same help contents each time
([#3516](https://togithub.com/psf/black/issues/3516))
- Verbose logging now shows the values of `pyproject.toml` configuration variables
([#3392](https://togithub.com/psf/black/issues/3392))
- Fix false symlink detection messages in verbose output due to using an incorrect
relative path to the project root ([#3385](https://togithub.com/psf/black/issues/3385))
##### Integrations
- Move 3.11 CI to normal flow now that all dependencies support 3.11 ([#3446](https://togithub.com/psf/black/issues/3446))
- Docker: Add new `latest_prerelease` tag automation to follow latest black alpha
release on docker images ([#3465](https://togithub.com/psf/black/issues/3465))
##### Documentation
- Expand `vim-plug` installation instructions to offer more explicit options ([#3468](https://togithub.com/psf/black/issues/3468))
