misplaced-comparison-constant (PLC2201) was deprecated in favor of SIM300 (#1980)
These two rules contain (nearly) identical logic. To deduplicate the rule set, we've upgraded
SIM300 to handle a few more cases, and deprecated PLC2201 in favor of SIM300.
@functools.cache rewrites have been moved to a standalone rule (UP033) (#1938)
Previously, UP011 handled both @functools.lru_cache()-to-@functools.lru_cache conversions,
and @functools.lru_cache(maxsize=None)-to-@functools.cache conversions. The latter has been
moved out to its own rule (UP033). As such, some # noqa: UP011 comments may need to be updated
to reflect the change in rule code.
--max-complexity has been removed from the CLI (#1877)
The McCabe plugin's --max-complexity setting has been removed from the CLI, for consistency with
the treatment of other, similar settings.
To set the maximum complexity, use the max-complexity property in your pyproject.toml file,
like so:
[tool.ruff.mccabe]
max-complexity = 10Files excluded by .gitignore are now ignored (#1234)
Ruff will now avoid checking files that are excluded by .ignore, .gitignore,
.git/info/exclude, and global gitignore files. This behavior is powered by the ignore
crate, and is applied in addition to Ruff's built-in exclude system.
To disable this behavior, set respect-gitignore = false in your pyproject.toml file.
Note that hidden files (i.e., files and directories prefixed with a .) are not ignored by
default.
Configuration files are now resolved hierarchically (#1190)
pyproject.toml files are now resolved hierarchically, such that for each Python file, we find
the first pyproject.toml file in its path, and use that to determine its lint settings.
See the README for more.
