 # Breaking Changes
 
-## 0.0.283 / 0.284
-
-### The target Python version now defaults to 3.8 instead of 3.10 ([#6397](https://github.com/astral-sh/ruff/pull/6397))
-
-Previously, when a target Python version was not specified, Ruff would use a default of Python 3.10. However, it is safer to default to an _older_ Python version to avoid assuming the availability of new features. We now default to the oldest supported Python version which is currently Python 3.8.
-
-(We still support Python 3.7 but since [it has reached EOL](https://devguide.python.org/versions/#unsupported-versions) we've decided not to make it the default here.)
-
-Note this change was announced in 0.0.283 but not active until 0.0.284.
-
-## 0.0.277
-
-### `.ipynb_checkpoints`, `.pyenv`, `.pytest_cache`, and `.vscode` are now excluded by default ([#5513](https://github.com/astral-sh/ruff/pull/5513))
-
-Ruff maintains a list of default exclusions, which now consists of the following patterns:
-
-- `.bzr`
-- `.direnv`
-- `.eggs`
-- `.git`
-- `.git-rewrite`
-- `.hg`
-- `.ipynb_checkpoints`
-- `.mypy_cache`
-- `.nox`
-- `.pants.d`
-- `.pyenv`
-- `.pytest_cache`
-- `.pytype`
-- `.ruff_cache`
-- `.svn`
-- `.tox`
-- `.venv`
-- `.vscode`
-- `__pypackages__`
-- `_build`
-- `buck-out`
-- `build`
-- `dist`
-- `node_modules`
-- `venv`
-
-Previously, the `.ipynb_checkpoints`, `.pyenv`, `.pytest_cache`, and `.vscode` directories were not
-excluded by default. This change brings Ruff's default exclusions in line with other tools like
-Black.
-
-## 0.0.276
-
-### The `keep-runtime-typing` setting has been reinstated ([#5470](https://github.com/astral-sh/ruff/pull/5470))
-
-The `keep-runtime-typing` setting has been reinstated with revised semantics. This setting was
-removed in [#4427](https://github.com/astral-sh/ruff/pull/4427), as it was equivalent to ignoring
-the `UP006` and `UP007` rules via Ruff's standard `ignore` mechanism.
-
-Taking `UP006` (rewrite `List[int]` to `list[int]`) as an example, the setting now behaves as
-follows:
-
-- On Python 3.7 and Python 3.8, setting `keep-runtime-typing = true` will cause Ruff to ignore
-    `UP006` violations, even if `from __future__ import annotations` is present in the file.
-    While such annotations are valid in Python 3.7 and Python 3.8 when combined with
-    `from __future__ import annotations`, they aren't supported by libraries like Pydantic and
-    FastAPI, which rely on runtime type checking.
-- On Python 3.9 and above, the setting has no effect, as `list[int]` is a valid type annotation,
-    and libraries like Pydantic and FastAPI support it without issue.
-
-In short: `keep-runtime-typing` can be used to ensure that Ruff doesn't introduce type annotations
-that are not supported at runtime by the current Python version, which are unsupported by libraries
-like Pydantic and FastAPI.
-
-Note that this is not a breaking change, but is included here to complement the previous removal
-of `keep-runtime-typing`.

-Enabling the `keep-runtime-typing` option, located under the `pyupgrade` section, is equivalent
-to ignoring the `UP006` and `UP007` rules via Ruff's standard `ignore` mechanism. As there's no

-This primarily affects the JSON API. Ruff's JSON representation used to represent the `fix` field as

 ### Example: Adding a new lint rule
 
 At a high level, the steps involved in adding a new lint rule are as follows:
 
-1. Determine a name for the new rule as per our [rule naming convention](#rule-naming-convention)
-    (e.g., `AssertFalse`, as in, "allow `assert False`").
-
-1. Create a file for your rule (e.g., `crates/ruff/src/rules/flake8_bugbear/rules/assert_false.rs`).
-
-1. In that file, define a violation struct (e.g., `pub struct AssertFalse`). You can grep for
-    `#[violation]` to see examples.
-
-1. In that file, define a function that adds the violation to the diagnostic list as appropriate
-    (e.g., `pub(crate) fn assert_false`) based on whatever inputs are required for the rule (e.g.,
-    an `ast::StmtAssert` node).
-
-1. Define the logic for invoking the diagnostic in `crates/ruff/src/checkers/ast/analyze` (for
-    AST-based rules), `crates/ruff/src/checkers/tokens.rs` (for token-based rules),
-    `crates/ruff/src/checkers/physical_lines.rs` (for text-based rules),
-    `crates/ruff/src/checkers/filesystem.rs` (for filesystem-based rules), etc. For AST-based rules,
-    you'll likely want to modify `analyze/statement.rs` (if your rule is based on analyzing
-    statements, like imports) or `analyze/expression.rs` (if your rule is based on analyzing
-    expressions, like function calls).
-
-1. Map the violation struct to a rule code in `crates/ruff/src/codes.rs` (e.g., `B011`).
-
-1. Add proper [testing](#rule-testing-fixtures-and-snapshots) for your rule.
-
+1. Determine a name for the new rule as per our [rule naming convention](#rule-naming-convention).
+1. Create a file for your rule (e.g., `crates/ruff/src/rules/flake8_bugbear/rules/abstract_base_class.rs`).
+1. In that file, define a violation struct. You can grep for `define_violation!` to see examples.
+1. Map the violation struct to a rule code in `crates/ruff/src/registry.rs` (e.g., `E402`).
+1. Define the logic for triggering the violation in `crates/ruff/src/checkers/ast.rs` (for AST-based
+   checks), `crates/ruff/src/checkers/tokens.rs` (for token-based checks), `crates/ruff/src/checkers/lines.rs`
+   (for text-based checks), or `crates/ruff/src/checkers/filesystem.rs` (for filesystem-based
+   checks).
+1. Add a test fixture.
 1. Update the generated files (documentation and generated code).
 
-To trigger the violation, you'll likely want to augment the logic in `crates/ruff/src/checkers/ast.rs`
-to call your new function at the appropriate time and with the appropriate inputs. The `Checker`
-defined therein is a Python AST visitor, which iterates over the AST, building up a semantic model,
-and calling out to lint rule analyzer functions as it goes.
+To define the violation, start by creating a dedicated file for your rule under the appropriate
+rule linter (e.g., `crates/ruff/src/rules/flake8_bugbear/rules/abstract_base_class.rs`). That file should
+contain a struct defined via `define_violation!`, along with a function that creates the violation
+based on any required inputs. (Many of the existing examples live in `crates/ruff/src/violations.rs`,
+but we're looking to place new rules in their own files.)
+
+To trigger the violation, you'll likely want to augment the logic in `crates/ruff/src/checkers/ast.rs`,
+which defines the Python AST visitor, responsible for iterating over the abstract syntax tree and
+collecting diagnostics as it goes.
 
 If you need to inspect the AST, you can run `cargo dev print-ast` with a Python file. Grep
-for the `Diagnostic::new` invocations to understand how other, similar rules are implemented.
+for the `Check::new` invocations to understand how other, similar rules are implemented.
 
-Once you're satisfied with your code, add tests for your rule. See [rule testing](#rule-testing-fixtures-and-snapshots)
-for more details.
+To add a test fixture, create a file under `crates/ruff/resources/test/fixtures/[linter]`, named to match
+the code you defined earlier (e.g., `crates/ruff/resources/test/fixtures/pycodestyle/E402.py`). This file should
+contain a variety of violations and non-violations designed to evaluate and demonstrate the behavior
+of your lint rule.
 
-Finally, regenerate the documentation and other generated assets (like our JSON Schema) with:
-`cargo dev generate-all`.
+Run `cargo dev generate-all` to generate the code for your new fixture. Then run Ruff

 #### Rule naming convention
 
-Like Clippy, Ruff's rule names should make grammatical and logical sense when read as "allow
-${rule}" or "allow ${rule} items", as in the context of suppression comments.
+The rule name should make sense when read as "allow _rule-name_" or "allow _rule-name_ items".
 
-For example, `AssertFalse` fits this convention: it flags `assert False` statements, and so a
-suppression comment would be framed as "allow `assert False`".
+This implies that rule names:
 
-As such, rule names should...
+- should state the bad thing being checked for
 
-- Highlight the pattern that is being linted against, rather than the preferred alternative.
-    For example, `AssertFalse` guards against `assert False` statements.
+- should not contain instructions on what you what you should use instead
+  (these belong in the rule documentation and the `autofix_title` for rules that have autofix)
 
-- _Not_ contain instructions on how to fix the violation, which instead belong in the rule
-    documentation and the `autofix_title`.
-
-- _Not_ contain a redundant prefix, like `Disallow` or `Banned`, which are already implied by the
-    convention.
-
-When re-implementing rules from other linters, we prioritize adhering to this convention over
+When re-implementing rules from other linters, this convention is given more importance than
 preserving the original rule name.
 
-#### Rule testing: fixtures and snapshots
-
-To test rules, Ruff uses snapshots of Ruff's output for a given file (fixture). Generally, there
-will be one file per rule (e.g., `E402.py`), and each file will contain all necessary examples of
-both violations and non-violations. `cargo insta review` will generate a snapshot file containing
-Ruff's output for each fixture, which you can then commit alongside your changes.
-
-Once you've completed the code for the rule itself, you can define tests with the following steps:
-
-1. Add a Python file to `crates/ruff/resources/test/fixtures/[linter]` that contains the code you
-    want to test. The file name should match the rule name (e.g., `E402.py`), and it should include
-    examples of both violations and non-violations.
-
-1. Run Ruff locally against your file and verify the output is as expected. Once you're satisfied
-    with the output (you see the violations you expect, and no others), proceed to the next step.
-    For example, if you're adding a new rule named `E402`, you would run:
-
-    ```shell
-    cargo run -p ruff_cli -- check crates/ruff/resources/test/fixtures/pycodestyle/E402.py --no-cache --select E402
-    ```
-
-    **Note:** Only a subset of rules are enabled by default. When testing a new rule, ensure that
-    you activate it by adding `--select ${rule_code}` to the command.
-
-1. Add the test to the relevant `crates/ruff/src/rules/[linter]/mod.rs` file. If you're contributing
-    a rule to a pre-existing set, you should be able to find a similar example to pattern-match
-    against. If you're adding a new linter, you'll need to create a new `mod.rs` file (see,
-    e.g., `crates/ruff/src/rules/flake8_bugbear/mod.rs`)
-
-1. Run `cargo test`. Your test will fail, but you'll be prompted to follow-up
-    with `cargo insta review`. Run `cargo insta review`, review and accept the generated snapshot,
-    then commit the snapshot file alongside the rest of your changes.
-
-1. Run `cargo test` again to ensure that your test passes.

-### Microbenchmarks
-
-The `ruff_benchmark` crate benchmarks the linter and the formatter on individual files.

-You can run the benchmarks with

-
-#### Benchmark-driven Development
-
-Ruff uses [Criterion.rs](https://bheisler.github.io/criterion.rs/book/) for benchmarks. You can use
-`--save-baseline=<name>` to store an initial baseline benchmark (e.g. on `main`) and then use
-`--benchmark=<name>` to compare against that benchmark. Criterion will print a message telling you
-if the benchmark improved/regressed compared to that baseline.
-
-```shell
-# Run once on your "baseline" code
-cargo benchmark --save-baseline=main
-
-# Then iterate with
-cargo benchmark --baseline=main
-```
-
-#### PR Summary
-
-You can use `--save-baseline` and `critcmp` to get a pretty comparison between two recordings.
-This is useful to illustrate the improvements of a PR.
-
-```shell
-# On main
-cargo benchmark --save-baseline=main
-
-# After applying your changes
-cargo benchmark --save-baseline=pr
-
-critcmp main pr
-```
-
-You must install [`critcmp`](https://github.com/BurntSushi/critcmp) for the comparison.
-
-```bash
-cargo install critcmp
-```
-
-#### Tips
-
-- Use `cargo benchmark <filter>` to only run specific benchmarks. For example: `cargo benchmark linter/pydantic`
-    to only run the pydantic tests.
-- Use `cargo benchmark --quiet` for a more cleaned up output (without statistical relevance)
-- Use `cargo benchmark --quick` to get faster results (more prone to noise)
-
-### Profiling Projects
-
-You can either use the microbenchmarks from above or a project directory for benchmarking. There
-are a lot of profiling tools out there,
-[The Rust Performance Book](https://nnethercote.github.io/perf-book/profiling.html) lists some
-examples.
-
-#### Linux
-
-Install `perf` and build `ruff_benchmark` with the `release-debug` profile and then run it with perf
-
-```shell
-cargo bench -p ruff_benchmark --no-run --profile=release-debug && perf record --call-graph dwarf -F 9999 cargo bench -p ruff_benchmark --profile=release-debug -- --profile-time=1
-```
-
-You can also use the `ruff_dev` launcher to run `ruff check` multiple times on a repository to
-gather enough samples for a good flamegraph (change the 999, the sample rate, and the 30, the number
-of checks, to your liking)
-
-```shell
-cargo build --bin ruff_dev --profile=release-debug
-perf record -g -F 999 target/release-debug/ruff_dev repeat --repeat 30 --exit-zero --no-cache path/to/cpython > /dev/null
-```
-
-Then convert the recorded profile
-
-```shell
-perf script -F +pid > /tmp/test.perf
-```
-
-You can now view the converted file with [firefox profiler](https://profiler.firefox.com/), with a
-more in-depth guide [here](https://profiler.firefox.com/docs/#/./guide-perf-profiling)
-
-An alternative is to convert the perf data to `flamegraph.svg` using
-[flamegraph](https://github.com/flamegraph-rs/flamegraph) (`cargo install flamegraph`):
-
-```shell
-flamegraph --perfdata perf.data --no-inline
-```
-
-#### Mac
-
-Install [`cargo-instruments`](https://crates.io/crates/cargo-instruments):
-
-```shell
-cargo install cargo-instruments
-```
-
-Then run the profiler with
-
-```shell
-cargo instruments -t time --bench linter --profile release-debug -p ruff_benchmark -- --profile-time=1
-```
-
-- `-t`: Specifies what to profile. Useful options are `time` to profile the wall time and `alloc`
-    for profiling the allocations.

-
-Otherwise, follow the instructions from the linux section.

-utils with it:
-

-    [RustPython parser](https://github.com/astral-sh/RustPython-Parser/tree/main/parser) that is
-    mainly used in Ruff. For `if True: pass # comment`, you can see the syntax tree, the byte offsets
-    for start and stop of each node and also how the `:` token, the comment and whitespace are not
-    represented anymore:

-## Subsystems
-
-### Compilation Pipeline
-
-If we view Ruff as a compiler, in which the inputs are paths to Python files and the outputs are
-diagnostics, then our current compilation pipeline proceeds as follows:
-
-1. **File discovery**: Given paths like `foo/`, locate all Python files in any specified subdirectories, taking into account our hierarchical settings system and any `exclude` options.
-
-1. **Package resolution**: Determine the "package root" for every file by traversing over its parent directories and looking for `__init__.py` files.
-
-1. **Cache initialization**: For every "package root", initialize an empty cache.
-
-1. **Analysis**: For every file, in parallel:
-
-    1. **Cache read**: If the file is cached (i.e., its modification timestamp hasn't changed since it was last analyzed), short-circuit, and return the cached diagnostics.
-
-    1. **Tokenization**: Run the lexer over the file to generate a token stream.
-
-    1. **Indexing**: Extract metadata from the token stream, such as: comment ranges, `# noqa` locations, `# isort: off` locations, "doc lines", etc.
-
-    1. **Token-based rule evaluation**: Run any lint rules that are based on the contents of the token stream (e.g., commented-out code).
-
-    1. **Filesystem-based rule evaluation**: Run any lint rules that are based on the contents of the filesystem (e.g., lack of `__init__.py` file in a package).
-
-    1. **Logical line-based rule evaluation**: Run any lint rules that are based on logical lines (e.g., stylistic rules).
-
-    1. **Parsing**: Run the parser over the token stream to produce an AST. (This consumes the token stream, so anything that relies on the token stream needs to happen before parsing.)
-
-    1. **AST-based rule evaluation**: Run any lint rules that are based on the AST. This includes the vast majority of lint rules. As part of this step, we also build the semantic model for the current file as we traverse over the AST. Some lint rules are evaluated eagerly, as we iterate over the AST, while others are evaluated in a deferred manner (e.g., unused imports, since we can't determine whether an import is unused until we've finished analyzing the entire file), after we've finished the initial traversal.
-
-    1. **Import-based rule evaluation**: Run any lint rules that are based on the module's imports (e.g., import sorting). These could, in theory, be included in the AST-based rule evaluation phase — they're just separated for simplicity.

-    1. **Physical line-based rule evaluation**: Run any lint rules that are based on physical lines (e.g., line-length).

-
-1. **Reporting**: Print diagnostics in the specified format (text, JSON, etc.), to the specified output channel (stdout, a file, etc.).
-
-### Import Categorization
-
-To understand Ruff's import categorization system, we first need to define two concepts:
-
-- "Project root": The directory containing the `pyproject.toml`, `ruff.toml`, or `.ruff.toml` file,
-    discovered by identifying the "closest" such directory for each Python file. (If you're running
-    via `ruff --config /path/to/pyproject.toml`, then the current working directory is used as the
-    "project root".)
-- "Package root": The top-most directory defining the Python package that includes a given Python
-    file. To find the package root for a given Python file, traverse up its parent directories until
-    you reach a parent directory that doesn't contain an `__init__.py` file (and isn't marked as
-    a [namespace package](https://beta.ruff.rs/docs/settings/#namespace-packages)); take the directory
-    just before that, i.e., the first directory in the package.
-
-For example, given:
-
-```text
-my_project
-├── pyproject.toml
-└── src
-    └── foo
-        ├── __init__.py
-        └── bar
-            ├── __init__.py
-            └── baz.py
-```
-
-Then when analyzing `baz.py`, the project root would be the top-level directory (`./my_project`),
-and the package root would be `./my_project/src/foo`.
-
-#### Project root
-
-The project root does not have a significant impact beyond that all relative paths within the loaded
-configuration file are resolved relative to the project root.
-
-For example, to indicate that `bar` above is a namespace package (it isn't, but let's run with it),
-the `pyproject.toml` would list `namespace-packages = ["./src/bar"]`, which would resolve
-to `my_project/src/bar`.
-
-The same logic applies when providing a configuration file via `--config`. In that case, the
-_current working directory_ is used as the project root, and so all paths in that configuration file
-are resolved relative to the current working directory. (As a general rule, we want to avoid relying
-on the current working directory as much as possible, to ensure that Ruff exhibits the same behavior
-regardless of where and how you invoke it — but that's hard to avoid in this case.)
-
-Additionally, if a `pyproject.toml` file _extends_ another configuration file, Ruff will still use
-the directory containing that `pyproject.toml` file as the project root. For example, if
-`./my_project/pyproject.toml` contains:
-
-```toml
-[tool.ruff]
-extend = "/path/to/pyproject.toml"
-```
-
-Then Ruff will use `./my_project` as the project root, even though the configuration file extends
-`/path/to/pyproject.toml`. As such, if the configuration file at `/path/to/pyproject.toml` contains
-any relative paths, they will be resolved relative to `./my_project`.
-
-If a project uses nested configuration files, then Ruff would detect multiple project roots, one for
-each configuration file.
-
-#### Package root
-
-The package root is used to determine a file's "module path". Consider, again, `baz.py`. In that
-case, `./my_project/src/foo` was identified as the package root, so the module path for `baz.py`
-would resolve to  `foo.bar.baz` — as computed by taking the relative path from the package root
-(inclusive of the root itself). The module path can be thought of as "the path you would use to
-import the module" (e.g., `import foo.bar.baz`).
-
-The package root and module path are used to, e.g., convert relative to absolute imports, and for
-import categorization, as described below.
-
-#### Import categorization
-
-When sorting and formatting import blocks, Ruff categorizes every import into one of five
-categories:
-
-1. **"Future"**: the import is a `__future__` import. That's easy: just look at the name of the
-    imported module!
-1. **"Standard library"**: the import comes from the Python standard library (e.g., `import os`).
-    This is easy too: we include a list of all known standard library modules in Ruff itself, so it's
-    a simple lookup.
-1. **"Local folder"**: the import is a relative import (e.g., `from .foo import bar`). This is easy
-    too: just check if the import includes a `level` (i.e., a dot-prefix).
-1. **"First party"**: the import is part of the current project. (More on this below.)
-1. **"Third party"**: everything else.
-
-The real challenge lies in determining whether an import is first-party — everything else is either
-trivial, or (as in the case of third-party) merely defined as "not first-party".
-
-There are three ways in which an import can be categorized as "first-party":
-
-1. **Explicit settings**: the import is marked as such via the `known-first-party` setting. (This
-    should generally be seen as an escape hatch.)
-1. **Same-package**: the imported module is in the same package as the current file. This gets back
-    to the importance of the "package root" and the file's "module path". Imagine that we're
-    analyzing `baz.py` above. If `baz.py` contains any imports that appear to come from the `foo`
-    package (e.g., `from foo import bar` or `import foo.bar`), they'll be classified as first-party
-    automatically. This check is as simple as comparing the first segment of the current file's
-    module path to the first segment of the import.
-1. **Source roots**: Ruff supports a `[src](https://beta.ruff.rs/docs/settings/#src)` setting, which
-    sets the directories to scan when identifying first-party imports. The algorithm is
-    straightforward: given an import, like `import foo`, iterate over the directories enumerated in
-    the `src` setting and, for each directory, check for the existence of a subdirectory `foo` or a
-    file `foo.py`.
-
-By default, `src` is set to the project root. In the above example, we'd want to set
-`src = ["./src"]` to ensure that we locate `./my_project/src/foo` and thus categorize `import foo`
-as first-party in `baz.py`. In practice, for this limited example, setting `src = ["./src"]` is
-unnecessary, as all imports within `./my_project/src/foo` would be categorized as first-party via
-the same-package heuristic; but your project contains multiple packages, you'll want to set `src`
-explicitly.

 ## Limitations
 
 1. Ruff only supports a subset of the Flake configuration options. `flake8-to-ruff` will warn on and
-    ignore unsupported options in the `.flake8` file (or equivalent). (Similarly, Ruff has a few
-    configuration options that don't exist in Flake8.)
