v0.0.292

What's Changed

Highlights

This release includes full support for Python 3.12 (out now!), including the new type parameter (PEP 695) and f-string syntaxes (PEP 701).

PEP 701 lifts many of the restrictions on f-strings that existed in the past, allowing for arbitrarily nested f-strings, consistent quote style within f-strings, and more, all of which are now supported by Ruff (thanks to @dhruvmanila in #7376).

Breaking Changes

• In the formatter, format.quote-style no longer affects triple-quoted strings, to align with common conventions as well as the guidance from PEP 8 and PEP 257 (see: #7680).
• line-too-long (E501) now ignores trailing pragma comments (like # type: ignore and # noqa) when computing line length (see: #7692). This is similar to flake8-bugbear's methodology for detecting overlong lines, and ensures that adding pragmas like # noqa does not introduce further lint errors.

Rules

• [refurb] Implement print-empty-string (FURB105) by @tjkuson in #7617
• [flake8-bandit] Implement weak-cryptographic-key (S505) by @mkniewallner in #7703
• [refurb] Implement implicit-cwd (FURB177) by @danparizher in #7704
• unnecessary-pass (PIE790) now flags all unnecessary pass statements; previously, the rule only flagged pass statements that followed a docstring in a two-statement body (see: #7697).

Settings

• Add lint section to Ruff configuration by @MichaReiser in #7549
• Add explicit-preview-rules to toggle explicit selection of preview rules by @zanieb in #7390
• Decrease PEP 593 error to a debug warning by @charliermarsh in #7745
• Write full Jupyter notebook to stdout by @charliermarsh in #7748
• Extend unnecessary-pass (PIE790) to trigger on all unnecessary pass statements by @tjkuson in #7697

Bug Fixes

• Ignore blank lines between comments when counting newlines-after-imports by @charliermarsh in #7607
• Avoid reordering mixed-indent-level comments after branches by @charliermarsh in #7609
