Release Notes

psf/black (psf/black)

`v26.3.0`

Compare Source

Stable style

Don't double-decode input, causing non-UTF-8 files to be corrupted (#4964)
Fix crash on standalone comment in lambda default arguments (#4993)
Preserve parentheses when # type: ignore comments would be merged with other
comments on the same line, preventing AST equivalence failures (#4888)

Preview style

Fix bug where if guards in case blocks were incorrectly split when the pattern had
a trailing comma (#4884)
Fix string_processing crashing on unassigned long string literals with trailing
commas (one-item tuples) (#4929)
Simplify implementation of the power operator "hugging" logic (#4918)

Packaging

Fix shutdown errors in PyInstaller builds on macOS by disabling multiprocessing in
frozen environments (#4930)

Performance

Introduce winloop for windows as an alternative to uvloop (#4996)
Remove deprecated function uvloop.install() in favor of uvloop.new_event_loop()
(#4996)
Rename maybe_install_uvloop function to maybe_use_uvloop to simplify loop
installation and creation of either a uvloop/winloop evenloop or default eventloop
(#4996)

Output

Emit a clear warning when the target Python version is newer than the running Python
version, since AST safety checks cannot parse newer syntax. Also replace the
misleading "INTERNAL ERROR" message with an actionable error explaining the version
mismatch (#4983)

Blackd

Introduce winloop to be used when windows in use which enables blackd to run faster on
windows when winloop is installed. (#4996)

Integrations

Remove unused gallery script (#5030)
Harden parsing of black requirements in the GitHub Action when use_pyproject is
enabled so that only version specifiers are accepted and direct references such as
black @ https://... are rejected. Users should upgrade to the latest version of the
action as soon as possible. This update is received automatically when using
psf/black@stable, and is independent of the version of Black installed by the
action. (#5031)

Documentation

Expand preview style documentation with detailed examples for wrap_comprehension_in,
simplify_power_operator_hugging, and wrap_long_dict_values_in_parens features
(#4987)
Add detailed documentation for formatting Jupyter Notebooks (#5009)
