-## 0.14.0
-
- **Default to Python 3.10**
-
-    Ruff now defaults to Python 3.10 instead of 3.9 if no explicit Python
-    version is configured using [`ruff.target-version`](https://docs.astral.sh/ruff/settings/#target-version)
-    or [`project.requires-python`](https://packaging.python.org/en/latest/guides/writing-pyproject-toml/#python-requires)
-    ([#20725](https://github.com/astral-sh/ruff/pull/20725))
-
- **Default to Python 3.14 for syntax errors**
-
-    Ruff will default to the _latest_ supported Python version (3.14) when
-    checking for syntax errors without a Python version configured. The default
-    in all other cases, like applying lint rules, remains at the minimum
-    supported Python version (3.10).

+guide and overview of the changes!

 ### Breaking changes

- Update default and latest Python versions for 3.14 ([#20725](https://github.com/astral-sh/ruff/pull/20725))
+- **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.
+
+### Removed Rules
+
+The following rules have been removed:
+
+- [`pandas-df-variable-name`](https://docs.astral.sh/ruff/rules/pandas-df-variable-name) (`PD901`)
+- [`non-pep604-isinstance`](https://docs.astral.sh/ruff/rules/non-pep604-isinstance) (`UP038`)
+
+### Stabilization
+
+The following rules have been stabilized and are no longer in preview:
+
+- [`airflow-dag-no-schedule-argument`](https://docs.astral.sh/ruff/rules/airflow-dag-no-schedule-argument)
+    (`AIR002`)
+- [`airflow3-removal`](https://docs.astral.sh/ruff/rules/airflow3-removal) (`AIR301`)
+- [`airflow3-moved-to-provider`](https://docs.astral.sh/ruff/rules/airflow3-moved-to-provider)
+    (`AIR302`)
+- [`airflow3-suggested-update`](https://docs.astral.sh/ruff/rules/airflow3-suggested-update)
+    (`AIR311`)
+- [`airflow3-suggested-to-move-to-provider`](https://docs.astral.sh/ruff/rules/airflow3-suggested-to-move-to-provider)
+    (`AIR312`)
+- [`long-sleep-not-forever`](https://docs.astral.sh/ruff/rules/long-sleep-not-forever) (`ASYNC116`)
+- [`f-string-number-format`](https://docs.astral.sh/ruff/rules/f-string-number-format) (`FURB116`)
+- [`os-symlink`](https://docs.astral.sh/ruff/rules/os-symlink) (`PTH211`)
+- [`generic-not-last-base-class`](https://docs.astral.sh/ruff/rules/generic-not-last-base-class)
+    (`PYI059`)
+- [`redundant-none-literal`](https://docs.astral.sh/ruff/rules/redundant-none-literal) (`PYI061`)
+- [`pytest-raises-ambiguous-pattern`](https://docs.astral.sh/ruff/rules/pytest-raises-ambiguous-pattern)
+    (`RUF043`)
+- [`unused-unpacked-variable`](https://docs.astral.sh/ruff/rules/unused-unpacked-variable)
+    (`RUF059`)
+- [`useless-class-metaclass-type`](https://docs.astral.sh/ruff/rules/useless-class-metaclass-type)
+    (`UP050`)
+
+The following behaviors have been stabilized:
+
+- [`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.

-## Finding ways to help
-
-We label issues that would be good for a first time contributor as
-[`good first issue`](https://github.com/astral-sh/ruff/issues?q=is%3Aopen+is%3Aissue+label%3A%22good+first+issue%22).
-These usually do not require significant experience with Rust or the Ruff code base.
-
-We label issues that we think are a good opportunity for subsequent contributions as
-[`help wanted`](https://github.com/astral-sh/ruff/issues?q=is%3Aopen+is%3Aissue+label%3A%22help+wanted%22).
-These require varying levels of experience with Rust and Ruff. Often, we want to accomplish these
-tasks but do not have the resources to do so ourselves.
-
-You don't need our permission to start on an issue we have labeled as appropriate for community
-contribution as described above. However, it's a good idea to indicate that you are going to work on
-an issue to avoid concurrent attempts to solve the same problem.
-
-Please check in with us before starting work on an issue that has not been labeled as appropriate
-for community contribution. We're happy to receive contributions for other issues, but it's
-important to make sure we have consensus on the solution to the problem first.
-
-Outside of issues with the labels above, issues labeled as
-[`bug`](https://github.com/astral-sh/ruff/issues?q=is%3Aopen+is%3Aissue+label%3A%22bug%22) are the
-best candidates for contribution. In contrast, issues labeled with `needs-decision` or
-`needs-design` are _not_ good candidates for contribution. Please do not open pull requests for
-issues with these labels.
-
-Please do not open pull requests for new features without prior discussion. While we appreciate
-exploration of new features, we will often close these pull requests immediately. Adding a
-new feature to ruff creates a long-term maintenance burden and requires strong consensus from the ruff
-team before it is appropriate to begin work on an implementation.

-
-### Breaking changes
-
- **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.
-
-### Removed Rules
-
-The following rules have been removed:
-
- [`pandas-df-variable-name`](https://docs.astral.sh/ruff/rules/pandas-df-variable-name) (`PD901`)
- [`non-pep604-isinstance`](https://docs.astral.sh/ruff/rules/non-pep604-isinstance) (`UP038`)

- [`useless-class-metaclass-type`](https://docs.astral.sh/ruff/rules/useless-class-metaclass-type)
-    (`UP050`)
-
-The following behaviors have been stabilized:
-
- [`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.

-## Preview
-When [preview] is enabled (and certain simplifying assumptions
-are met), we analyze all import statements for a given module
-when determining whether an import is used, rather than simply
-the last of these statements. This can result in both different and
-more import statements being marked as unused.
-
-For example, if a module consists of
-
-```python
-import a
-import a.b
-```
-
-then both statements are marked as unused under [preview], whereas
-only the second is marked as unused under stable behavior.
-
-As another example, if a module consists of
-
-```python
-import a.b
-import a
-
-a.b.foo()
-```
-
-then a diagnostic will only be emitted for the first line under [preview],
-whereas a diagnostic would only be emitted for the second line under
-stable behavior.
-
-Note that this behavior is somewhat subjective and is designed
-to conform to the developer's intuition rather than Python's actual
-execution. To wit, the statement `import a.b` automatically executes
-`import a`, so in some sense `import a` is _always_ redundant
-in the presence of `import a.b`.
-
-
 ## Fix safety

 Fixes to remove unused imports are safe, except in `__init__.py` files.

-# unused-import (F401)
-
-Derived from the **Pyflakes** linter.
-
-Fix is sometimes available.
-
-## What it does
-Checks for unused imports.
-
-## Why is this bad?
-Unused imports add a performance overhead at runtime, and risk creating
-import cycles. They also increase the cognitive load of reading the code.
-
-If an import statement is used to check for the availability or existence
-of a module, consider using `importlib.util.find_spec` instead.
-
-If an import statement is used to re-export a symbol as part of a module's
-public interface, consider using a "redundant" import alias, which
-instructs Ruff (and other tools) to respect the re-export, and avoid
-marking it as unused, as in:
-
-```python
-from module import member as member
-```
-
-Alternatively, you can use `__all__` to declare a symbol as part of the module's
-interface, as in:
-
-```python
-# __init__.py
-import some_module
-
-__all__ = ["some_module"]
-```
-
-## Preview
-When [preview] is enabled (and certain simplifying assumptions
-are met), we analyze all import statements for a given module
-when determining whether an import is used, rather than simply
-the last of these statements. This can result in both different and
-more import statements being marked as unused.
-
-For example, if a module consists of
-
-```python
-import a
-import a.b
-```
-
-then both statements are marked as unused under [preview], whereas
-only the second is marked as unused under stable behavior.
-
-As another example, if a module consists of
-
-```python
-import a.b
-import a
-
-a.b.foo()
-```
-
-then a diagnostic will only be emitted for the first line under [preview],
-whereas a diagnostic would only be emitted for the second line under
-stable behavior.
-
-Note that this behavior is somewhat subjective and is designed
-to conform to the developer's intuition rather than Python's actual
-execution. To wit, the statement `import a.b` automatically executes
-`import a`, so in some sense `import a` is _always_ redundant
-in the presence of `import a.b`.
-
-
-## Fix safety
-
-Fixes to remove unused imports are safe, except in `__init__.py` files.
-
-Applying fixes to `__init__.py` files is currently in preview. The fix offered depends on the
-type of the unused import. Ruff will suggest a safe fix to export first-party imports with
-either a redundant alias or, if already present in the file, an `__all__` entry. If multiple
-`__all__` declarations are present, Ruff will not offer a fix. Ruff will suggest an unsafe fix
-to remove third-party and standard library imports -- the fix is unsafe because the module's
-interface changes.
-
-See [this FAQ section](https://docs.astral.sh/ruff/faq/#how-does-ruff-determine-which-of-my-imports-are-first-party-third-party-etc)
-for more details on how Ruff
-determines whether an import is first or third-party.
-
-## Example
-
-```python
-import numpy as np  # unused import
-
-
-def area(radius):
-    return 3.14 * radius**2
-```
-
-Use instead:
-
-```python
-def area(radius):
-    return 3.14 * radius**2
-```
-
-To check the availability of a module, use `importlib.util.find_spec`:
-
-```python
-from importlib.util import find_spec
-
-if find_spec("numpy") is not None:
-    print("numpy is installed")
-else:
-    print("numpy is not installed")
-```
-
