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)
