Breaking changes
Detection of more syntax errors
Ruff now detects version-related syntax errors, such as the use of the match
statement on Python versions before 3.10, and syntax errors emitted by
CPython's compiler, such as irrefutable match patterns before the final
case arm.
New default Python version handling for syntax errors
Ruff will default to the latest supported Python version (3.13) when
checking for the version-related syntax errors mentioned above to prevent
false positives in projects without a Python version configured. The default
in all other cases, like applying lint rules, is unchanged and remains at the
minimum supported Python version (3.9).
Updated f-string formatting
Ruff now formats multi-line f-strings with format specifiers to avoid adding a
line break after the format specifier. This addresses a change to the Python
grammar in version 3.13.4 that made such a line break a syntax error.
rust-toolchain.toml is no longer included in source distributions
The rust-toolchain.toml is used to specify a higher Rust version than Ruff's
minimum supported Rust version (MSRV) for development and building release
artifacts. However, when present in source distributions, it would also cause
downstream package maintainers to pull in the same Rust toolchain, even if
their available toolchain was MSRV-compatible.
