 # Breaking Changes

-## 0.13.0
-
- **Several rules can now add `from __future__ import annotations` automatically**
-
-    `TC001`, `TC002`, `TC003`, `RUF013`, and `UP037` now add `from __future__ import annotations` as part of their fixes when the
-    `lint.future-annotations` setting is enabled. This allows the rules to move
-    more imports into `TYPE_CHECKING` blocks (`TC001`, `TC002`, and `TC003`),
-    use PEP 604 union syntax on Python versions before 3.10 (`RUF013`), and
-    unquote more annotations (`UP037`).
-
- **Full module paths are now used to verify first-party modules**
-
-    Ruff now checks that the full path to a module exists on disk before
-    categorizing it as a first-party import. This change makes first-party
-    import detection more accurate, helping to avoid false positives on local
-    directories with the same name as a third-party dependency, for example. See
-    the [FAQ
-    section](https://docs.astral.sh/ruff/faq/#how-does-ruff-determine-which-of-my-imports-are-first-party-third-party-etc) on import categorization for more details.
-
- **Deprecated rules must now be selected by exact rule code**
-
-    Ruff will no longer activate deprecated rules selected by their group name
-    or prefix. As noted below, the two remaining deprecated rules were also
-    removed in this release, so this won't affect any current rules, but it will
-    still affect any deprecations in the future.
-
- **The deprecated macOS configuration directory fallback has been removed**
-
-    Ruff will no longer look for a user-level configuration file at
-    `~/Library/Application Support/ruff/ruff.toml` on macOS. This feature was
-    deprecated in v0.5 in favor of using the [XDG
-    specification](https://specifications.freedesktop.org/basedir-spec/latest/)
-    (usually resolving to `~/.config/ruff/ruff.toml`), like on Linux. The
-    fallback and accompanying deprecation warning have now been removed.
-
- **[`pandas-df-variable-name`](https://docs.astral.sh/ruff/rules/pandas-df-variable-name) (`PD901`) has been removed**
-
- **[`non-pep604-isinstance`](https://docs.astral.sh/ruff/rules/non-pep604-isinstance) (`UP038`) has been removed**
-
 ## 0.12.0

 ### Breaking changes

- **Several rules can now add `from __future__ import annotations` automatically**
+- **Detection of more syntax errors**

-    `TC001`, `TC002`, `TC003`, `RUF013`, and `UP037` now add `from __future__ import annotations` as part of their fixes when the
-    `lint.future-annotations` setting is enabled. This allows the rules to move
-    more imports into `TYPE_CHECKING` blocks (`TC001`, `TC002`, and `TC003`),
-    use PEP 604 union syntax on Python versions before 3.10 (`RUF013`), and
-    unquote more annotations (`UP037`).
+    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.

- **Full module paths are now used to verify first-party modules**
+- **New default Python version handling for syntax errors**

-    Ruff now checks that the full path to a module exists on disk before
-    categorizing it as a first-party import. This change makes first-party
-    import detection more accurate, helping to avoid false positives on local
-    directories with the same name as a third-party dependency, for example. See
-    the [FAQ
-    section](https://docs.astral.sh/ruff/faq/#how-does-ruff-determine-which-of-my-imports-are-first-party-third-party-etc) on import categorization for more details.
+    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).

- **Deprecated rules must now be selected by exact rule code**
+- **Updated f-string formatting**

-    Ruff will no longer activate deprecated rules selected by their group name
-    or prefix. As noted below, the two remaining deprecated rules were also
-    removed in this release, so this won't affect any current rules, but it will
-    still affect any deprecations in the future.
+    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.

- **The deprecated macOS configuration directory fallback has been removed**
+- **`rust-toolchain.toml` is no longer included in source distributions**

-    Ruff will no longer look for a user-level configuration file at
-    `~/Library/Application Support/ruff/ruff.toml` on macOS. This feature was
-    deprecated in v0.5 in favor of using the [XDG
-    specification](https://specifications.freedesktop.org/basedir-spec/latest/)
-    (usually resolving to `~/.config/ruff/ruff.toml`), like on Linux. The
-    fallback and accompanying deprecation warning have now been removed.
+    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.

- [`assert-raises-exception`](https://docs.astral.sh/ruff/rules/assert-raises-exception) (`B017`)
-    now checks for direct calls to `unittest.TestCase.assert_raises` and `pytest.raises` instead of
-    only the context manager forms.
- [`missing-trailing-comma`](https://docs.astral.sh/ruff/rules/missing-trailing-comma) (`COM812`)
-    and [`prohibited-trailing-comma`](https://docs.astral.sh/ruff/rules/prohibited-trailing-comma)
-    (`COM819`) now check for trailing commas in PEP 695 type parameter lists.
- [`raw-string-in-exception`](https://docs.astral.sh/ruff/rules/raw-string-in-exception) (`EM101`)
-    now also checks for byte strings in exception messages.
- [`invalid-mock-access`](https://docs.astral.sh/ruff/rules/invalid-mock-access) (`PGH005`) now
-    checks for `AsyncMock` methods like `not_awaited` in addition to the synchronous variants.
- [`useless-import-alias`](https://docs.astral.sh/ruff/rules/useless-import-alias) (`PLC0414`) no
-    longer applies to `__init__.py` files, where it conflicted with one of the suggested fixes for
-    [`unused-import`](https://docs.astral.sh/ruff/rules/unused-import) (`F401`).
- [`bidirectional-unicode`](https://docs.astral.sh/ruff/rules/bidirectional-unicode) (`PLE2502`) now
-    also checks for U+061C (Arabic Letter Mark).
- The fix for
-    [`multiple-with-statements`](https://docs.astral.sh/ruff/rules/multiple-with-statements)
-    (`SIM117`) is now marked as always safe.
+- [`collection-literal-concatenation`] (`RUF005`) now recognizes slices, in
+    addition to list literals and variables.
+- The fix for [`readlines-in-for`] (`FURB129`) is now marked as always safe.
+- [`if-else-block-instead-of-if-exp`] (`SIM108`) will now further simplify
+    expressions to use `or` instead of an `if` expression, where possible.
+- [`unused-noqa`] (`RUF100`) now checks for file-level `noqa` comments as well
+    as inline comments.
+- [`subprocess-without-shell-equals-true`] (`S603`) now accepts literal strings,
+    as well as lists and tuples of literal strings, as trusted input.
+- [`boolean-type-hint-positional-argument`] (`FBT001`) now applies to types that
+    include `bool`, like `bool | int` or `typing.Optional[bool]`, in addition to
+    plain `bool` annotations.
+- [`non-pep604-annotation-union`] (`UP007`) has now been split into two rules.
+    `UP007` now applies only to `typing.Union`, while
+    [`non-pep604-annotation-optional`] (`UP045`) checks for use of
+    `typing.Optional`. `UP045` has also been stabilized in this release, but you
+    may need to update existing `include`, `ignore`, or `noqa` settings to
+    accommodate this change.

-
-## 0.12.0
-
-Check out the [blog post](https://astral.sh/blog/ruff-v0.12.0) for a migration
-guide and overview of the changes!
-
-### 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.
-
-### Removed Rules
-
-The following rules have been removed:
-
- [`suspicious-xmle-tree-usage`](https://docs.astral.sh/ruff/rules/suspicious-xmle-tree-usage/)
-    (`S320`)
-
-### Deprecated Rules

-The following rules have been deprecated:
-
- [`pandas-df-variable-name`](https://docs.astral.sh/ruff/rules/pandas-df-variable-name/)

- [`private-type-parameter`](https://docs.astral.sh/ruff/rules/private-type-parameter) (`UP049`)
-
-The following behaviors have been stabilized:
-
- [`collection-literal-concatenation`] (`RUF005`) now recognizes slices, in
-    addition to list literals and variables.
- The fix for [`readlines-in-for`] (`FURB129`) is now marked as always safe.
- [`if-else-block-instead-of-if-exp`] (`SIM108`) will now further simplify
-    expressions to use `or` instead of an `if` expression, where possible.
- [`unused-noqa`] (`RUF100`) now checks for file-level `noqa` comments as well
-    as inline comments.
- [`subprocess-without-shell-equals-true`] (`S603`) now accepts literal strings,
-    as well as lists and tuples of literal strings, as trusted input.
- [`boolean-type-hint-positional-argument`] (`FBT001`) now applies to types that
-    include `bool`, like `bool | int` or `typing.Optional[bool]`, in addition to
-    plain `bool` annotations.
- [`non-pep604-annotation-union`] (`UP007`) has now been split into two rules.
-    `UP007` now applies only to `typing.Union`, while
-    [`non-pep604-annotation-optional`] (`UP045`) checks for use of
-    `typing.Optional`. `UP045` has also been stabilized in this release, but you
-    may need to update existing `include`, `ignore`, or `noqa` settings to
-    accommodate this change.

-    For now, the primary difference is the movement of the filename, line number, and column information to a second line in the header.

-/// ## What it does
-/// Checks for uses of the `open()` builtin.
-///
-/// ## Why is this bad?
-/// `pathlib` offers a high-level API for path manipulation. When possible,
-/// using `Path` object methods such as `Path.open()` can improve readability
-/// over the `open` builtin.
-///
-/// ## Examples
-/// ```python
-/// with open("f1.py", "wb") as fp:
-///     ...
-/// ```
-///
-/// Use instead:
-/// ```python
-/// from pathlib import Path
-///
-/// with Path("f1.py").open("wb") as fp:
-///     ...
-/// ```
-///
-/// ## Known issues
-/// While using `pathlib` can improve the readability and type safety of your code,
-/// it can be less performant than working directly with strings,
-/// especially on older versions of Python.
-///
-/// ## Fix Safety
-/// This rule's fix is marked as unsafe if the replacement would remove comments attached to the original expression.
-///
-/// ## References
-/// - [Python documentation: `Path.open`](https://docs.python.org/3/library/pathlib.html#pathlib.Path.open)
-/// - [Python documentation: `open`](https://docs.python.org/3/library/functions.html#open)

+/// ## What it does
+/// Checks for uses of the `open()` builtin.
+///
+/// ## Why is this bad?
+/// `pathlib` offers a high-level API for path manipulation. When possible,
+/// using `Path` object methods such as `Path.open()` can improve readability
+/// over the `open` builtin.
+///
+/// ## Examples
+/// ```python
+/// with open("f1.py", "wb") as fp:
+///     ...
+/// ```
+///
+/// Use instead:
+/// ```python
+/// from pathlib import Path
+///
+/// with Path("f1.py").open("wb") as fp:
+///     ...
+/// ```
+///
+/// ## Known issues
+/// While using `pathlib` can improve the readability and type safety of your code,
+/// it can be less performant than working directly with strings,
+/// especially on older versions of Python.
+///
+/// ## References
+/// - [Python documentation: `Path.open`](https://docs.python.org/3/library/pathlib.html#pathlib.Path.open)
