 # Breaking Changes
 
-## 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).
-
-## 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
-
-- **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.
-
-- **[`suspicious-xmle-tree-usage`](https://docs.astral.sh/ruff/rules/suspicious-xmle-tree-usage/)
-    (`S320`) has been removed**
-
-## 0.11.0
-
-This is a follow-up to release 0.10.0. Because of a mistake in the release process, the `requires-python` inference changes were not included in that release. Ruff 0.11.0 now includes this change as well as the stabilization of the preview behavior for `PGH004`.
-
-- **Changes to how the Python version is inferred when a `target-version` is not specified** ([#16319](https://github.com/astral-sh/ruff/pull/16319))
-
-    In previous versions of Ruff, you could specify your Python version with:
-
-    - The `target-version` option in a `ruff.toml` file or the `[tool.ruff]` section of a pyproject.toml file.
-    - The `project.requires-python` field in a `pyproject.toml` file with a `[tool.ruff]` section.
-
-    These options worked well in most cases, and are still recommended for fine control of the Python version. However, because of the way Ruff discovers config files, `pyproject.toml` files without a `[tool.ruff]` section would be ignored, including the `requires-python` setting. Ruff would then use the default Python version (3.9 as of this writing) instead, which is surprising when you've attempted to request another version.
-
-    In v0.10, config discovery has been updated to address this issue:
-
-    - If Ruff finds a `ruff.toml` file without a `target-version`, it will check
-        for a `pyproject.toml` file in the same directory and respect its
-        `requires-python` version, even if it does not contain a `[tool.ruff]`
-        section.
-    - If Ruff finds a user-level configuration, the `requires-python` field of the closest `pyproject.toml` in a parent directory will take precedence.
-    - If there is no config file (`ruff.toml`or `pyproject.toml` with a
-        `[tool.ruff]` section) in the directory of the file being checked, Ruff will
-        search for the closest `pyproject.toml` in the parent directories and use its
-        `requires-python` setting.
-
-## 0.10.0
-
-- **Changes to how the Python version is inferred when a `target-version` is not specified** ([#16319](https://github.com/astral-sh/ruff/pull/16319))
-
-    Because of a mistake in the release process, the `requires-python` inference changes are not included in this release and instead shipped as part of 0.11.0.
-    You can find a description of this change in the 0.11.0 section.
-
-- **Updated `TYPE_CHECKING` behavior** ([#16669](https://github.com/astral-sh/ruff/pull/16669))
-
-    Previously, Ruff only recognized typechecking blocks that tested the `typing.TYPE_CHECKING` symbol. Now, Ruff recognizes any local variable named `TYPE_CHECKING`. This release also removes support for the legacy `if 0:` and `if False:` typechecking checks. Use a local `TYPE_CHECKING` variable instead.
-
-- **More robust noqa parsing** ([#16483](https://github.com/astral-sh/ruff/pull/16483))
-
-    The syntax for both file-level and in-line suppression comments has been unified and made more robust to certain errors. In most cases, this will result in more suppression comments being read by Ruff, but there are a few instances where previously read comments will now log an error to the user instead. Please refer to the documentation on [_Error suppression_](https://docs.astral.sh/ruff/linter/#error-suppression) for the full specification.
-
-- **Avoid unnecessary parentheses around with statements with a single context manager and a trailing comment** ([#14005](https://github.com/astral-sh/ruff/pull/14005))
-
-    This change fixes a bug in the formatter where it introduced unnecessary parentheses around with statements with a single context manager and a trailing comment. This change may result in a change in formatting for some users.
-
-- **Bump alpine default tag to 3.21 for derived Docker images** ([#16456](https://github.com/astral-sh/ruff/pull/16456))
-
-    Alpine 3.21 was released in Dec 2024 and is used in the official Alpine-based Python images. Now the ruff:alpine image will use 3.21 instead of 3.20 and ruff:alpine3.20 will no longer be updated.
-
-- **\[`unsafe-markup-use`\]: `RUF035` has been recoded to `S704`** ([#15957](https://github.com/astral-sh/ruff/pull/15957))
-

 Welcome! We're happy to have you here. Thank you in advance for your contribution to Ruff.

-## 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.
-
 ## The Basics
 
+Ruff welcomes contributions in the form of pull requests.
+
+For small changes (e.g., bug fixes), feel free to submit a PR.
+
+For larger changes (e.g., new lint rules, new functionality, new configuration options), consider
+creating an [**issue**](https://github.com/astral-sh/ruff/issues) outlining your proposed change.
+You can also join us on [Discord](https://discord.com/invite/astral-sh) to discuss your idea with the
+community. We've labeled [beginner-friendly tasks](https://github.com/astral-sh/ruff/issues?q=is%3Aissue+is%3Aopen+label%3A%22good+first+issue%22)
+in the issue tracker, along with [bugs](https://github.com/astral-sh/ruff/issues?q=is%3Aissue+is%3Aopen+label%3Abug)
+and [improvements](https://github.com/astral-sh/ruff/issues?q=is%3Aissue+is%3Aopen+label%3Aaccepted)
+that are ready for contributions.
+
+If you have suggestions on how we might improve the contributing documentation, [let us know](https://github.com/astral-sh/ruff/discussions/5693)!

-### Opening a PR
-
-After you finish your changes, the next step is to open a PR. By default, two
-sections will be filled into the PR body: the summary and the test plan.
-
-#### The summary
-
-The summary is intended to give us as maintainers information about your PR.
-This should typically include a link to the relevant issue(s) you're addressing
-in your PR, as well as a summary of the issue and your approach to fixing it. If
-you have any questions about your approach or design, or if you considered
-alternative approaches, that can also be helpful to include.
-
-AI can be helpful in generating both the code and summary of your PR, but a
-successful contribution should still be carefully reviewed by you and the
-summary editorialized before submitting a PR. A great summary is thorough but
-also succinct and gives us the context we need to review your PR.
-
-You can find examples of excellent issues and PRs by searching for the
-[`great writeup`](https://github.com/astral-sh/ruff/issues?q=label%3A%22great%20writeup%22)
-label.
-
-#### The test plan
-
-The test plan is likely to be shorter than the summary and can be as simple as
-"Added new snapshot tests for `RUF123`," at least for rule bugs. For LSP or some
-types of CLI changes, in particular, it can also be helpful to include
-screenshots or recordings of your change in action.
-
-#### Ecosystem report
-
-After opening the PR, an ecosystem report will be run as part of CI. This shows
-a diff of linter and formatter behavior before and after the changes in your PR.
-Going through these changes and reporting your findings in the PR summary or an
-additional comment help us to review your PR more efficiently. It's also a great
-way to find new test cases to incorporate into your PR if you identify any
-issues.
-
-#### PR status
-
-To help us know when your PR is ready for review again, please either move your
-PR back to a draft while working on it (marking it ready for review afterwards
-will ping the previous reviewers) or explicitly re-request a review. This helps
-us to avoid re-reviewing a PR while you're still working on it and also to
-prioritize PRs that are definitely ready for review.
-
-You can also thumbs-up or mark as resolved any comments we leave to let us know
-you addressed them.

-
-## 0.10.0
-
-Check out the [blog post](https://astral.sh/blog/ruff-v0.10.0) for a migration guide and overview of the changes!
-
-### Breaking changes
-
-See also, the "Remapped rules" section which may result in disabled rules.
-
-- **Changes to how the Python version is inferred when a `target-version` is not specified** ([#16319](https://github.com/astral-sh/ruff/pull/16319))
-
-    Because of a mistake in the release process, the `requires-python` inference changes are not included in this release and instead shipped as part of 0.11.0.
-    You can find a description of this change in the 0.11.0 section.
-
-- **Updated `TYPE_CHECKING` behavior** ([#16669](https://github.com/astral-sh/ruff/pull/16669))
-
-    Previously, Ruff only recognized typechecking blocks that tested the `typing.TYPE_CHECKING` symbol. Now, Ruff recognizes any local variable named `TYPE_CHECKING`. This release also removes support for the legacy `if 0:` and `if False:` typechecking checks. Use a local `TYPE_CHECKING` variable instead.
-
-- **More robust noqa parsing** ([#16483](https://github.com/astral-sh/ruff/pull/16483))
-
-    The syntax for both file-level and in-line suppression comments has been unified and made more robust to certain errors. In most cases, this will result in more suppression comments being read by Ruff, but there are a few instances where previously read comments will now log an error to the user instead. Please refer to the documentation on [_Error suppression_](https://docs.astral.sh/ruff/linter/#error-suppression) for the full specification.
-
-- **Avoid unnecessary parentheses around with statements with a single context manager and a trailing comment** ([#14005](https://github.com/astral-sh/ruff/pull/14005))
-
-    This change fixes a bug in the formatter where it introduced unnecessary parentheses around with statements with a single context manager and a trailing comment. This change may result in a change in formatting for some users.
-
-- **Bump alpine default tag to 3.21 for derived Docker images** ([#16456](https://github.com/astral-sh/ruff/pull/16456))
-
-    Alpine 3.21 was released in Dec 2024 and is used in the official Alpine-based Python images. Now the ruff:alpine image will use 3.21 instead of 3.20 and ruff:alpine3.20 will no longer be updated.

-- [`redundant-open-modes`](https://docs.astral.sh/ruff/rules/redundant-open-modes/) (`UP015`): The diagnostic range is now the range of the redundant mode argument where it previously was the range of the entire open call. You may have to replace your `noqa` comments when suppressing `UP015`.
-- [`stdlib-module-shadowing`](https://docs.astral.sh/ruff/rules/stdlib-module-shadowing/) (`A005`): Changes the default value of `lint.flake8-builtins.strict-checking` from `true` to `false`.

-# Changelog 0.11.x
-
-## 0.11.0
-
-This is a follow-up to release 0.10.0. Because of a mistake in the release process, the `requires-python` inference changes were not included in that release. Ruff 0.11.0 now includes this change as well as the stabilization of the preview behavior for `PGH004`.
-
-### Breaking changes
-
-- **Changes to how the Python version is inferred when a `target-version` is not specified** ([#16319](https://github.com/astral-sh/ruff/pull/16319))
-
-    In previous versions of Ruff, you could specify your Python version with:
-
-    - The `target-version` option in a `ruff.toml` file or the `[tool.ruff]` section of a pyproject.toml file.
-    - The `project.requires-python` field in a `pyproject.toml` file with a `[tool.ruff]` section.
-
-    These options worked well in most cases, and are still recommended for fine control of the Python version. However, because of the way Ruff discovers config files, `pyproject.toml` files without a `[tool.ruff]` section would be ignored, including the `requires-python` setting. Ruff would then use the default Python version (3.9 as of this writing) instead, which is surprising when you've attempted to request another version.
-
-    In v0.10, config discovery has been updated to address this issue:
-
-    - If Ruff finds a `ruff.toml` file without a `target-version`, it will check
-        for a `pyproject.toml` file in the same directory and respect its
-        `requires-python` version, even if it does not contain a `[tool.ruff]`
-        section.
-    - If Ruff finds a user-level configuration, the `requires-python` field of the closest `pyproject.toml` in a parent directory will take precedence.
-    - If there is no config file (`ruff.toml`or `pyproject.toml` with a
-        `[tool.ruff]` section) in the directory of the file being checked, Ruff will
-        search for the closest `pyproject.toml` in the parent directories and use its
-        `requires-python` setting.
-
-### Stabilization
-
-The following behaviors have been stabilized:
-
-- [`blanket-noqa`](https://docs.astral.sh/ruff/rules/blanket-noqa/) (`PGH004`): Also detect blanked file-level noqa comments (and not just line level comments).

-
-## 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.

-    Below is an example diff for [`F401`](https://docs.astral.sh/ruff/rules/unused-import/):
-
-    ```diff

-
-    For now, the primary difference is the movement of the filename, line number, and column information to a second line in the header. This new representation will allow us to make further additions to Ruff's diagnostics, such as adding sub-diagnostics and multiple annotations to the same snippet.

-
-## 0.13.0
-
-Check out the [blog post](https://astral.sh/blog/ruff-v0.13.0) for a migration
-guide and overview of the changes!
-
-### 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
-

-# Changelog 0.4.x
-
-## 0.4.0
-
-### A new, hand-written parser
-
-Ruff's new parser is **>2x faster**, which translates to a **20-40% speedup** for all linting and formatting invocations.
-There's a lot to say about this exciting change, so check out the [blog post](https://astral.sh/blog/ruff-v0.4.0) for more details!
-
-See [#10036](https://github.com/astral-sh/ruff/pull/10036) for implementation details.
-
-### A new language server in Rust
-
-With this release, we also want to highlight our new language server. `ruff server` is a Rust-powered language
-server that comes built-in with Ruff. It can be used with any editor that supports the [Language Server Protocol](https://microsoft.github.io/language-server-protocol/) (LSP).
-It uses a multi-threaded, lock-free architecture inspired by `rust-analyzer` and it will open the door for a lot
-of exciting features. It’s also faster than our previous [Python-based language server](https://github.com/astral-sh/ruff-lsp)
--- but you probably guessed that already.
-
-`ruff server` is only in alpha, but it has a lot of features that you can try out today:
-
-- Lints Python files automatically and shows quick-fixes when available
-- Formats Python files, with support for range formatting
-- Comes with commands for quickly performing actions: `ruff.applyAutofix`, `ruff.applyFormat`, and `ruff.applyOrganizeImports`
-- Supports `source.fixAll` and `source.organizeImports` source actions
-- Automatically reloads your project configuration when you change it
-
-To setup `ruff server` with your editor, refer to the [README.md](https://github.com/astral-sh/ruff/blob/main/crates/ruff_server/README.md).

-
-## 0.7.0
-
-Check out the [blog post](https://astral.sh/blog/ruff-v0.7.0) for a migration guide and overview of the changes!
-
-### Breaking changes
-
-- The pytest rules `PT001` and `PT023` now default to omitting the decorator parentheses when there are no arguments
-    ([#12838](https://github.com/astral-sh/ruff/pull/12838), [#13292](https://github.com/astral-sh/ruff/pull/13292)).
-    This was a change that we attempted to make in Ruff v0.6.0, but only partially made due to an error on our part.
-    See the [blog post](https://astral.sh/blog/ruff-v0.7.0) for more details.
-- The `useless-try-except` rule (in our `tryceratops` category) has been recoded from `TRY302` to
-    `TRY203` ([#13502](https://github.com/astral-sh/ruff/pull/13502)). This ensures Ruff's code is consistent with
-    the same rule in the [`tryceratops`](https://github.com/guilatrova/tryceratops) linter.
-- The `lint.allow-unused-imports` setting has been removed ([#13677](https://github.com/astral-sh/ruff/pull/13677)). Use
-    [`lint.pyflakes.allow-unused-imports`](https://docs.astral.sh/ruff/settings/#lint_pyflakes_allowed-unused-imports)
-    instead.
-
-### Formatter preview style

-# Changelog 0.8.x
-
-## 0.8.0
-
-Check out the [blog post](https://astral.sh/blog/ruff-v0.8.0) for a migration guide and overview of the changes!
-
-### Breaking changes
-
-See also, the "Remapped rules" section which may result in disabled rules.
-
-- **Default to Python 3.9**
-
-    Ruff now defaults to Python 3.9 instead of 3.8 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) ([#13896](https://github.com/astral-sh/ruff/pull/13896))
-
-- **Changed location of `pydoclint` diagnostics**
-
-    [`pydoclint`](https://docs.astral.sh/ruff/rules/#pydoclint-doc) diagnostics now point to the first-line of the problematic docstring. Previously, this was not the case.
-
-    If you've opted into these preview rules but have them suppressed using
-    [`noqa`](https://docs.astral.sh/ruff/linter/#error-suppression) comments in
-    some places, this change may mean that you need to move the `noqa` suppression
-    comments. Most users should be unaffected by this change.
-
-- **Use XDG (i.e. `~/.local/bin`) instead of the Cargo home directory in the standalone installer**
-
-    Previously, Ruff's installer used `$CARGO_HOME` or `~/.cargo/bin` for its target install directory. Now, Ruff will be installed into `$XDG_BIN_HOME`, `$XDG_DATA_HOME/../bin`, or `~/.local/bin` (in that order).
-
-    This change is only relevant to users of the standalone Ruff installer (using the shell or PowerShell script). If you installed Ruff using uv or pip, you should be unaffected.
-
-- **Changes to the line width calculation**
-
-    Ruff now uses a new version of the [unicode-width](https://github.com/unicode-rs/unicode-width) Rust crate to calculate the line width. In very rare cases, this may lead to lines containing Unicode characters being reformatted, or being considered too long when they were not before ([`E501`](https://docs.astral.sh/ruff/rules/line-too-long/)).
-
-### Removed Rules
-
-The following deprecated rules have been removed:
-
-- [`missing-type-self`](https://docs.astral.sh/ruff/rules/missing-type-self/) (`ANN101`)
-- [`missing-type-cls`](https://docs.astral.sh/ruff/rules/missing-type-cls/) (`ANN102`)

-- [`unpacked-list-comprehension`](https://docs.astral.sh/ruff/rules/unpacked-list-comprehension/) (`UP027`)
-
-### Remapped rules
-
-The following rules have been remapped to new rule codes:
-
-- [`flake8-type-checking`](https://docs.astral.sh/ruff/rules/#flake8-type-checking-tc): `TCH` to `TC`
-

-### Stabilization
-
-The following rules have been stabilized and are no longer in preview:
-
-- [`stdlib-module-shadowing`](https://docs.astral.sh/ruff/rules/stdlib-module-shadowing/) (`A005`).
-    This rule has also been renamed: previously, it was called `builtin-module-shadowing`.
-- [`builtin-lambda-argument-shadowing`](https://docs.astral.sh/ruff/rules/builtin-lambda-argument-shadowing/) (`A006`)

-
-### Formatter
-
-This release introduces the new 2025 stable style ([#13371](https://github.com/astral-sh/ruff/issues/13371)), stabilizing the following changes:
-
-- Format expressions in f-string elements ([#7594](https://github.com/astral-sh/ruff/issues/7594))
-- Alternate quotes for strings inside f-strings ([#13860](https://github.com/astral-sh/ruff/pull/13860))
-- Preserve the casing of hex codes in f-string debug expressions ([#14766](https://github.com/astral-sh/ruff/issues/14766))
-- Choose the quote style for each string literal in an implicitly concatenated f-string rather than for the entire string ([#13539](https://github.com/astral-sh/ruff/pull/13539))
-- Automatically join an implicitly concatenated string into a single string literal if it fits on a single line ([#9457](https://github.com/astral-sh/ruff/issues/9457))
-- Remove the [`ISC001`](https://docs.astral.sh/ruff/rules/single-line-implicit-string-concatenation/) incompatibility warning ([#15123](https://github.com/astral-sh/ruff/pull/15123))
-- Prefer parenthesizing the `assert` message over breaking the assertion expression ([#9457](https://github.com/astral-sh/ruff/issues/9457))
-- Automatically parenthesize over-long `if` guards in `match` `case` clauses ([#13513](https://github.com/astral-sh/ruff/pull/13513))
-- More consistent formatting for `match` `case` patterns ([#6933](https://github.com/astral-sh/ruff/issues/6933))
-- Avoid unnecessary parentheses around return type annotations ([#13381](https://github.com/astral-sh/ruff/pull/13381))
-- Keep the opening parentheses on the same line as the `if` keyword for comprehensions where the condition has a leading comment ([#12282](https://github.com/astral-sh/ruff/pull/12282))
-- More consistent formatting for `with` statements with a single context manager for Python 3.8 or older ([#10276](https://github.com/astral-sh/ruff/pull/10276))
-- Correctly calculate the line-width for code blocks in docstrings when using `max-doc-code-line-length = "dynamic"` ([#13523](https://github.com/astral-sh/ruff/pull/13523))
-
-### Preview features
-
-- \[`flake8-bugbear`\] Implement `class-as-data-structure` (`B903`) ([#9601](https://github.com/astral-sh/ruff/pull/9601))
-- \[`flake8-type-checking`\] Apply `quoted-type-alias` more eagerly in `TYPE_CHECKING` blocks and ignore it in stubs (`TC008`) ([#15180](https://github.com/astral-sh/ruff/pull/15180))
-- \[`pylint`\] Ignore `eq-without-hash` in stub files (`PLW1641`) ([#15310](https://github.com/astral-sh/ruff/pull/15310))
-- \[`pyupgrade`\] Split `UP007` into two individual rules: `UP007` for `Union` and `UP045` for `Optional` (`UP007`, `UP045`) ([#15313](https://github.com/astral-sh/ruff/pull/15313))
-- \[`ruff`\] New rule that detects classes that are both an enum and a `dataclass` (`RUF049`) ([#15299](https://github.com/astral-sh/ruff/pull/15299))

-### Rule changes
-
-- \[`flake8-builtins`\] Ignore [`stdlib-module-shadowing`](https://docs.astral.sh/ruff/rules/stdlib-module-shadowing/) in stub files(`A005`) ([#15350](https://github.com/astral-sh/ruff/pull/15350))

-
-### Server
-
-- Improve the observability by removing the need for the ["trace" value](https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#traceValue) to turn on or off logging. The server logging is solely controlled using the [`logLevel` server setting](https://docs.astral.sh/ruff/editors/settings/#loglevel)
-    which defaults to `info`. This addresses the issue where users were notified about an error and told to consult the log, but it didn’t contain any messages. ([#15232](https://github.com/astral-sh/ruff/pull/15232))

+# Tracing
+
+Traces are a useful tool to narrow down the location of a bug or, at least, to understand why the compiler is doing a particular thing.
+Note, tracing messages with severity `debug` or greater are user-facing. They should be phrased accordingly.
+Tracing spans are only shown when using `-vvv`.
+
+## Verbosity levels
+
+The CLI supports different verbosity levels.
+
+- default: Only show errors and warnings.
+- `-v` activates `info!`: Show generally useful information such as paths of configuration files, detected platform, etc., but it's not a lot of messages, it's something you'll activate in CI by default. cargo build e.g. shows you which packages are fresh.
+- `-vv` activates `debug!` and timestamps: This should be enough information to get to the bottom of bug reports. When you're processing many packages or files, you'll get pages and pages of output, but each line is link to a specific action or state change.
+- `-vvv` activates `trace!` (only in debug builds) and shows tracing-spans: At this level, you're logging everything. Most of this is wasted, it's really slow, we dump e.g. the entire resolution graph. Only useful to developers, and you almost certainly want to use `RED_KNOT_LOG` to filter it down to the area your investigating.
+
+## Better logging with `RED_KNOT_LOG` and `RAYON_NUM_THREADS`
+
+By default, the CLI shows messages from the `ruff` and `red_knot` crates. Tracing messages from other crates are not shown.
+The `RED_KNOT_LOG` environment variable allows you to customize which messages are shown by specifying one
+or more [filter directives](https://docs.rs/tracing-subscriber/latest/tracing_subscriber/filter/struct.EnvFilter.html#directives).
+
+The `RAYON_NUM_THREADS` environment variable, meanwhile, can be used to control the level of concurrency red-knot uses.
+By default, red-knot will attempt to parallelize its work so that multiple files are checked simultaneously,
+but this can result in a confused logging output where messages from different threads are intertwined.
+To switch off concurrency entirely and have more readable logs, use `RAYON_NUM_THREADS=1`.
+
+### Examples
+
+#### Show all debug messages
+
+Shows debug messages from all crates.
+
+```bash
+RED_KNOT_LOG=debug
+```
+
+#### Show salsa query execution messages
+
+Show the salsa `execute: my_query` messages in addition to all red knot messages.
+
+```bash
+RED_KNOT_LOG=ruff=trace,red_knot=trace,salsa=info
+```
+
+#### Show typing traces
+
+Only show traces for the `red_knot_python_semantic::types` module.
+
+```bash
+RED_KNOT_LOG="red_knot_python_semantic::types"
+```
+
+Note: Ensure that you use `-vvv` to see tracing spans.
+
+#### Show messages for a single file
+
+Shows all messages that are inside of a span for a specific file.
+
+```bash
+RED_KNOT_LOG=red_knot[{file=/home/micha/astral/test/x.py}]=trace
+```
+
+**Note**: Tracing still shows all spans because tracing can't know at the time of entering the span
+whether one if its children has the file `x.py`.
+
+**Note**: Salsa currently logs the entire memoized values. In our case, the source text and parsed AST.
+This very quickly leads to extremely long outputs.
+
+## Tracing and Salsa
+
+Be mindful about using `tracing` in Salsa queries, especially when using `warn` or `error` because it isn't guaranteed
+that the query will execute after restoring from a persistent cache. In which case the user won't see the message.
+
+For example, don't use `tracing` to show the user a message when generating a lint violation failed
+because the message would only be shown when linting the file the first time, but not on subsequent analysis
+runs or when restoring from a persistent cache. This can be confusing for users because they
+don't understand why a specific lint violation isn't raised. Instead, change your
+query to return the failure as part of the query's result or use a Salsa accumulator.
+
+## Tracing in tests
+
+You can use `ruff_db::testing::setup_logging` or `ruff_db::testing::setup_logging_with_filter` to set up logging in tests.
+
+```rust
+use ruff_db::testing::setup_logging;
+
+#[test]
+fn test() {
+  let _logging = setup_logging();
+
+  tracing::info!("This message will be printed to stderr");
+}
+```
+
+Note: Most test runners capture stderr and only show its output when a test fails.
+
+Note also that `setup_logging` only sets up logging for the current thread because [`set_global_default`](https://docs.rs/tracing/latest/tracing/subscriber/fn.set_global_default.html) can only be
+called **once**.
+
+## Release builds
+
+`trace!` events are removed in release builds.
+
+## Profiling
+
+Red Knot generates a folded stack trace to the current directory named `tracing.folded` when setting the environment variable `RED_KNOT_LOG_PROFILE` to `1` or `true`.
+
+```bash
+RED_KNOT_LOG_PROFILE=1 red_knot -- --current-directory=../test -vvv
+```
+
+You can convert the textual representation into a visual one using `inferno`.
+
+```shell
+cargo install inferno
+```
+
+```shell
+# flamegraph
+cat tracing.folded | inferno-flamegraph > tracing-flamegraph.svg
+
+# flamechart
+cat tracing.folded | inferno-flamegraph --flamechart > tracing-flamechart.svg
+```
+

+# `Annotated`
+
+`Annotated` attaches arbitrary metadata to a given type.
+
+## Usages
+
+`Annotated[T, ...]` is equivalent to `T`: All metadata arguments are simply ignored.
+
+```py
+from typing_extensions import Annotated
+
+def _(x: Annotated[int, "foo"]):
+    reveal_type(x)  # revealed: int
+
+def _(x: Annotated[int, lambda: 0 + 1 * 2 // 3, _(4)]):
+    reveal_type(x)  # revealed: int
+
+def _(x: Annotated[int, "arbitrary", "metadata", "elements", "are", "fine"]):
+    reveal_type(x)  # revealed: int
+
+def _(x: Annotated[tuple[str, int], bytes]):
+    reveal_type(x)  # revealed: tuple[str, int]
+```
+
+## Parameterization
+
+It is invalid to parameterize `Annotated` with less than two arguments.
+
+```py
+from typing_extensions import Annotated
+
+# error: [invalid-type-form] "`Annotated` requires at least two arguments when used in an annotation or type expression"
+def _(x: Annotated):
+    reveal_type(x)  # revealed: Unknown

+## Annotation

+`typing.Any` is a way to name the Any type.

+x = "foo"
+
+def f():
+    reveal_type(x)  # revealed: Any

+## Aliased to a different name
+
+If you alias `typing.Any` to another name, we still recognize that as a spelling of the Any type.

+x = "foo"
+
+def f():
+    reveal_type(x)  # revealed: Any
+```
+
+## Shadowed class
+
+If you define your own class named `Any`, using that in a type expression refers to your class, and
+isn't a spelling of the Any type.
+
+```py
+class Any: ...
+
+x: Any
+
+def f():
+    reveal_type(x)  # revealed: Any
+
+# This verifies that we're not accidentally seeing typing.Any, since str is assignable

+
+## Subclass
+
+The spec allows you to define subclasses of `Any`.
+
+TODO: Handle assignments correctly. `Subclass` has an unknown superclass, which might be `int`. The
+assignment to `x` should not be allowed, even when the unknown superclass is `int`. The assignment
+to `y` should be allowed, since `Subclass` might have `int` as a superclass, and is therefore
+assignable to `int`.

+```py

+## Unions with possibly unbound paths
+
+### Definite boundness within a class
+
+In this example, the `x` attribute is not defined in the `C2` element of the union:
+
+```py

+    class C1:
+        x = 1

+    # error: [possibly-unbound-attribute] "Attribute `x` on type `Literal[C1, C2, C3]` is possibly unbound"
+    reveal_type(C.x)  # revealed: Literal[1, 3]
+```
+
+### Possibly-unbound within a class
+
+We raise the same diagnostic if the attribute is possibly-unbound in at least one element of the
+union:
+
+```py
+def _(flag: bool, flag1: bool, flag2: bool):
+    class C1:
+        x = 1
+
+    class C2:
+        if flag:
+            x = 2
+
+    class C3:
+        x = 3
+
+    C = C1 if flag1 else C2 if flag2 else C3
+
+    # error: [possibly-unbound-attribute] "Attribute `x` on type `Literal[C1, C2, C3]` is possibly unbound"
+    reveal_type(C.x)  # revealed: Literal[1, 2, 3]
+```
+
+## Unions with all paths unbound
+
+If the symbol is unbound in all elements of the union, we detect that:
+
+```py
+def _(flag: bool):
+    class C1: ...
+    class C2: ...
+    C = C1 if flag else C2
+
+    # error: [unresolved-attribute] "Type `Literal[C1, C2]` has no attribute `x`"

+reveal_type(f.__call__)  # revealed: @Todo(`__call__` method on functions)
+```
+
+## Int-literal attributes
+
+Most attribute accesses on int-literal types are delegated to `builtins.int`, since all literal
+integers are instances of that class:
+
+```py path=a.py

+reveal_type((2).real)  # revealed: Literal[2]
+```
+
+## Literal `bool` attributes
+
+Most attribute accesses on bool-literal types are delegated to `builtins.bool`, since all literal
+bols are instances of that class:
+
+```py path=a.py
+reveal_type(True.__and__)  # revealed: @Todo(instance attributes)

+reveal_type(B() | A())  # revealed: A
+```
+
+## Returning a different type
+
+The magic methods aren't required to return the type of `self`:
+
+```py
+class A:
+    def __add__(self, other) -> int:
+        return 1
+
+    def __rsub__(self, other) -> int:
+        return 1
+
+class B: ...
+
+reveal_type(A() + B())  # revealed: int
+reveal_type(B() - A())  # revealed: int
+```
+
+## Non-reflected precedence in general
+
+In general, if the left-hand side defines `__add__` and the right-hand side defines `__radd__` and
+the right-hand side is not a subtype of the left-hand side, `lhs.__add__` will take precedence:
+
+```py
+class A:
+    def __add__(self, other: B) -> int:
+        return 42
+
+class B:
+    def __radd__(self, other: A) -> str:
+        return "foo"
+
+reveal_type(A() + B())  # revealed:  int
+
+# Edge case: C is a subtype of C, *but* if the two sides are of *equal* types,
+# the lhs *still* takes precedence
+class C:
+    def __add__(self, other: C) -> int:
+        return 42
+
+    def __radd__(self, other: C) -> str:
+        return "foo"
+
+reveal_type(C() + C())  # revealed: int
+```
+
+## Reflected precedence for subtypes (in some cases)
+
+If the right-hand operand is a subtype of the left-hand operand and has a different implementation
+of the reflected method, the reflected method on the right-hand operand takes precedence.
+
+```py
+class A:
+    def __add__(self, other) -> str:
+        return "foo"
+
+    def __radd__(self, other) -> str:
+        return "foo"
+
+class MyString(str): ...
+
+class B(A):
+    def __radd__(self, other) -> MyString:
+        return MyString()
+
+reveal_type(A() + B())  # revealed: MyString
+
+# N.B. Still a subtype of `A`, even though `A` does not appear directly in the class's `__bases__`
+class C(B): ...
+
+reveal_type(A() + C())  # revealed: MyString
+```
+
+## Reflected precedence 2
+
+If the right-hand operand is a subtype of the left-hand operand, but does not override the reflected
+method, the left-hand operand's non-reflected method still takes precedence:
+
+```py
+class A:
+    def __add__(self, other) -> str:
+        return "foo"
+
+    def __radd__(self, other) -> int:
+        return 42
+
+class B(A): ...
+
+reveal_type(A() + B())  # revealed: str
+```
+
+## Only reflected supported
+
+For example, at runtime, `(1).__add__(1.2)` is `NotImplemented`, but `(1.2).__radd__(1) == 2.2`,
+meaning that `1 + 1.2` succeeds at runtime (producing `2.2`). The runtime tries the second one only
+if the first one returns `NotImplemented` to signal failure.
+
+Typeshed and other stubs annotate dunder-method calls that would return `NotImplemented` as being
+"illegal" calls. `int.__add__` is annotated as only "accepting" `int`s, even though it
+strictly-speaking "accepts" any other object without raising an exception -- it will simply return
+`NotImplemented`, allowing the runtime to try the `__radd__` method of the right-hand operand as
+well.
+
+```py
+class A:
+    def __sub__(self, other: A) -> A:
+        return A()
+
+class B:
+    def __rsub__(self, other: A) -> B:
+        return B()
+
+# TODO: this should be `B` (the return annotation of `B.__rsub__`),
+# because `A.__sub__` is annotated as only accepting `A`,
+# but `B.__rsub__` will accept `A`.
+reveal_type(A() - B())  # revealed: A
+```
+
+## Callable instances as dunders
+
+Believe it or not, this is supported at runtime:
+
+```py
+class A:
+    def __call__(self, other) -> int:
+        return 42
+
+class B:
+    __add__ = A()
+
+reveal_type(B() + B())  # revealed: int
+```
+
+## Integration test: numbers from typeshed
+
+```py
+reveal_type(3j + 3.14)  # revealed: complex
+reveal_type(4.2 + 42)  # revealed: float
+reveal_type(3j + 3)  # revealed: complex

+
+    # TODO should be float, need to check arg type and fall back to `rhs.__radd__`
+    reveal_type(y + 4.12)  # revealed: int
+```
+
+## With literal types
+
+When we have a literal type for one operand, we're able to fall back to the instance handling for
+its instance super-type.
+
+```py
+class A:
+    def __add__(self, other) -> A:
+        return self
+
+    def __radd__(self, other) -> A:
+        return self
+
+reveal_type(A() + 1)  # revealed: A
+# TODO should be `A` since `int.__add__` doesn't support `A` instances
+reveal_type(1 + A())  # revealed: int
+
+reveal_type(A() + "foo")  # revealed: A
+# TODO should be `A` since `str.__add__` doesn't support `A` instances
+# TODO overloads
+reveal_type("foo" + A())  # revealed: @Todo(return type)
+
+reveal_type(A() + b"foo")  # revealed: A
+# TODO should be `A` since `bytes.__add__` doesn't support `A` instances
+reveal_type(b"foo" + A())  # revealed: bytes
+
+reveal_type(A() + ())  # revealed: A
+# TODO this should be `A`, since `tuple.__add__` doesn't support `A` instances
+reveal_type(() + A())  # revealed: @Todo(return type)
+
+literal_string_instance = "foo" * 1_000_000_000
+# the test is not testing what it's meant to be testing if this isn't a `LiteralString`:
+reveal_type(literal_string_instance)  # revealed: LiteralString
+
+reveal_type(A() + literal_string_instance)  # revealed: A
+# TODO should be `A` since `str.__add__` doesn't support `A` instances
+# TODO overloads
+reveal_type(literal_string_instance + A())  # revealed: @Todo(return type)
+```
+
+## Operations involving instances of classes inheriting from `Any`
+
+`Any` and `Unknown` represent a set of possible runtime objects, wherein the bounds of the set are
+unknown. Whether the left-hand operand's dunder or the right-hand operand's reflected dunder depends
+on whether the right-hand operand is an instance of a class that is a subclass of the left-hand
+operand's class and overrides the reflected dunder. In the following example, because of the
+unknowable nature of `Any`/`Unknown`, we must consider both possibilities: `Any`/`Unknown` might
+resolve to an unknown third class that inherits from `X` and overrides `__radd__`; but it also might
+not. Thus, the correct answer here for the `reveal_type` is `int | Unknown`.
+
+```py
+from does_not_exist import Foo  # error: [unresolved-import]
+
+reveal_type(Foo)  # revealed: Unknown
+
+class X:
+    def __add__(self, other: object) -> int:
+        return 42
+
+class Y(Foo): ...
+
+# TODO: Should be `int | Unknown`; see above discussion.
+reveal_type(X() + Y())  # revealed: int
+```
+
+## Unsupported
+
+### Dunder as instance attribute
+
+The magic method must exist on the class, not just on the instance:
+
+```py
+def add_impl(self, other) -> int:
+    return 1
+
+class A:
+    def __init__(self):
+        self.__add__ = add_impl
+
+# error: [unsupported-operator] "Operator `+` is unsupported between objects of type `A` and `A`"
+# revealed: Unknown
+reveal_type(A() + A())
+```
+
+### Missing dunder
+
+```py
+class A: ...
+
+# error: [unsupported-operator]
+# revealed: Unknown
+reveal_type(A() + A())
+```
+
+### Wrong position
+
+A left-hand dunder method doesn't apply for the right-hand operand, or vice versa:
+
+```py
+class A:
+    def __add__(self, other) -> int: ...
+
+class B:
+    def __radd__(self, other) -> int: ...
+
+class C: ...
+
+# error: [unsupported-operator]
+# revealed: Unknown
+reveal_type(C() + A())
+
+# error: [unsupported-operator]
+# revealed: Unknown
+reveal_type(B() + C())
+```
+
+### Reflected dunder is not tried between two objects of the same type
+
+For the specific case where the left-hand operand is the exact same type as the right-hand operand,
+the reflected dunder of the right-hand operand is not tried; the runtime short-circuits after trying
+the unreflected dunder of the left-hand operand. For context, see
+[this mailing list discussion](https://mail.python.org/archives/list/python-dev@python.org/thread/7NZUCODEAPQFMRFXYRMGJXDSIS3WJYIV/).
+
+```py
+class Foo:
+    def __radd__(self, other: Foo) -> Foo:
+        return self
+
+# error: [unsupported-operator]
+# revealed: Unknown
+reveal_type(Foo() + Foo())
+```
+

+
+## Division by Zero
+
+This error is really outside the current Python type system, because e.g. `int.__truediv__` and
+friends are not annotated to indicate that it's an error, and we don't even have a facility to
+permit such an annotation. So arguably divide-by-zero should be a lint error rather than a type
+checker error. But we choose to go ahead and error in the cases that are very likely to be an error:
+dividing something typed as `int` or `float` by something known to be `Literal[0]`.
+
+This isn't _definitely_ an error, because the object typed as `int` or `float` could be an instance
+of a custom subclass which overrides division behavior to handle zero without error. But if this
+unusual case occurs, the error can be avoided by explicitly typing the dividend as that safe custom
+subclass; we only emit the error if the LHS type is exactly `int` or `float`, not if its a subclass.
+
+```py
+a = 1 / 0  # error: "Cannot divide object of type `Literal[1]` by zero"
+reveal_type(a)  # revealed: float
+
+b = 2 // 0  # error: "Cannot floor divide object of type `Literal[2]` by zero"
