Bumps black from 24.10.0 to 26.3.1.

Release notes

Sourced from black's releases.

26.3.1

Stable style

  • Prevent Jupyter notebook magic masking collisions from corrupting cells by using exact-length placeholders for short magics and aborting if a placeholder can no longer be unmasked safely (#5038)

Configuration

  • Always hash cache filename components derived from --python-cell-magics so custom magic names cannot affect cache paths (#5038)

Blackd

  • Disable browser-originated requests by default, add configurable origin allowlisting and request body limits, and bound executor submissions to improve backpressure (#5039)

26.3.0

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
