+# Breaking Changes
+
+## 0.0.226
+
+### `misplaced-comparison-constant` (`PLC2201`) was deprecated in favor of `SIM300` ([#1980](https://github.com/charliermarsh/ruff/pull/1980))
+
+These two rules contain (nearly) identical logic. To deduplicate the rule set, we've upgraded
+`SIM300` to handle a few more cases, and deprecated `PLC2201` in favor of `SIM300`.
+
+## 0.0.225
+
+### `@functools.cache` rewrites have been moved to a standalone rule (`UP033`) ([#1938](https://github.com/charliermarsh/ruff/pull/1938))
+
+Previously, `UP011` handled both `@functools.lru_cache()`-to-`@functools.lru_cache` conversions,
+_and_ `@functools.lru_cache(maxsize=None)`-to-`@functools.cache` conversions. The latter has been
+moved out to its own rule (`UP033`). As such, some `# noqa: UP011` comments may need to be updated
+to reflect the change in rule code.
+
+## 0.0.222
+
+### `--max-complexity` has been removed from the CLI ([#1877](https://github.com/charliermarsh/ruff/pull/1877))
+
+The McCabe plugin's `--max-complexity` setting has been removed from the CLI, for consistency with
+the treatment of other, similar settings.
+
+To set the maximum complexity, use the `max-complexity` property in your `pyproject.toml` file,
+like so:
+
+```toml
+[tool.ruff.mccabe]
+max-complexity = 10
+```
+
+## 0.0.181
+
+### Files excluded by `.gitignore` are now ignored ([#1234](https://github.com/charliermarsh/ruff/pull/1234))
+
+Ruff will now avoid checking files that are excluded by `.ignore`, `.gitignore`,
+`.git/info/exclude`, and global `gitignore` files. This behavior is powered by the [`ignore`](https://docs.rs/ignore/latest/ignore/struct.WalkBuilder.html#ignore-rules)
+crate, and is applied in addition to Ruff's built-in `exclude` system.
+
+To disable this behavior, set `respect-gitignore = false` in your `pyproject.toml` file.
+
+Note that hidden files (i.e., files and directories prefixed with a `.`) are _not_ ignored by
+default.
+
+## 0.0.178
+
+### Configuration files are now resolved hierarchically ([#1190](https://github.com/charliermarsh/ruff/pull/1190))
+
+`pyproject.toml` files are now resolved hierarchically, such that for each Python file, we find
+the first `pyproject.toml` file in its path, and use that to determine its lint settings.
+
+See the [README](https://github.com/charliermarsh/ruff#pyprojecttoml-discovery) for more.

+# Contributor Covenant Code of Conduct
+
+## Our Pledge
+
+We as members, contributors, and leaders pledge to make participation in our
+community a harassment-free experience for everyone, regardless of age, body
+size, visible or invisible disability, ethnicity, sex characteristics, gender
+identity and expression, level of experience, education, socio-economic status,
+nationality, personal appearance, race, religion, or sexual identity
+and orientation.
+
+We pledge to act and interact in ways that contribute to an open, welcoming,
+diverse, inclusive, and healthy community.
+
+## Our Standards
+
+Examples of behavior that contributes to a positive environment for our
+community include:
+
+* Demonstrating empathy and kindness toward other people
+* Being respectful of differing opinions, viewpoints, and experiences
+* Giving and gracefully accepting constructive feedback
+* Accepting responsibility and apologizing to those affected by our mistakes,
+  and learning from the experience
+* Focusing on what is best not just for us as individuals, but for the
+  overall community
+
+Examples of unacceptable behavior include:
+
+* The use of sexualized language or imagery, and sexual attention or
+  advances of any kind
+* Trolling, insulting or derogatory comments, and personal or political attacks
+* Public or private harassment
+* Publishing others' private information, such as a physical or email
+  address, without their explicit permission
+* Other conduct which could reasonably be considered inappropriate in a
+  professional setting
+
+## Enforcement Responsibilities
+
+Community leaders are responsible for clarifying and enforcing our standards of
+acceptable behavior and will take appropriate and fair corrective action in
+response to any behavior that they deem inappropriate, threatening, offensive,
+or harmful.
+
+Community leaders have the right and responsibility to remove, edit, or reject
+comments, commits, code, wiki edits, issues, and other contributions that are
+not aligned to this Code of Conduct, and will communicate reasons for moderation
+decisions when appropriate.
+
+## Scope
+
+This Code of Conduct applies within all community spaces, and also applies when
+an individual is officially representing the community in public spaces.
+Examples of representing our community include using an official e-mail address,
+posting via an official social media account, or acting as an appointed
+representative at an online or offline event.
+
+## Enforcement
+
+Instances of abusive, harassing, or otherwise unacceptable behavior may be
+reported to the community leaders responsible for enforcement at
+charlie.r.marsh@gmail.com.
+All complaints will be reviewed and investigated promptly and fairly.
+
+All community leaders are obligated to respect the privacy and security of the
+reporter of any incident.
+
+## Enforcement Guidelines
+
+Community leaders will follow these Community Impact Guidelines in determining
+the consequences for any action they deem in violation of this Code of Conduct:
+
+### 1. Correction
+
+**Community Impact**: Use of inappropriate language or other behavior deemed
+unprofessional or unwelcome in the community.
+
+**Consequence**: A private, written warning from community leaders, providing
+clarity around the nature of the violation and an explanation of why the
+behavior was inappropriate. A public apology may be requested.
+
+### 2. Warning
+
+**Community Impact**: A violation through a single incident or series
+of actions.
+
+**Consequence**: A warning with consequences for continued behavior. No
+interaction with the people involved, including unsolicited interaction with
+those enforcing the Code of Conduct, for a specified period of time. This
+includes avoiding interactions in community spaces as well as external channels
+like social media. Violating these terms may lead to a temporary or
+permanent ban.
+
+### 3. Temporary Ban
+
+**Community Impact**: A serious violation of community standards, including
+sustained inappropriate behavior.
+
+**Consequence**: A temporary ban from any sort of interaction or public
+communication with the community for a specified period of time. No public or
+private interaction with the people involved, including unsolicited interaction
+with those enforcing the Code of Conduct, is allowed during this period.
+Violating these terms may lead to a permanent ban.
+
+### 4. Permanent Ban
+
+**Community Impact**: Demonstrating a pattern of violation of community
+standards, including sustained inappropriate behavior,  harassment of an
+individual, or aggression toward or disparagement of classes of individuals.
+
+**Consequence**: A permanent ban from any sort of public interaction within
+the community.

+# Contributing to Ruff
+
+Welcome! We're happy to have you here. Thank you in advance for your contribution to Ruff.
+
+## 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 submitting an [Issue](https://github.com/charliermarsh/ruff/issues) outlining
+your proposed change.
+
+If you're looking for a place to start, we recommend implementing a new lint rule (see:
+[_Adding a new lint rule_](#example-adding-a-new-lint-rule), which will allow you to learn from and
+pattern-match against the examples in the existing codebase. Many lint rules are inspired by
+existing Python plugins, which can be used as a reference implementation.
+
+As a concrete example: consider taking on one of the rules from the [`tryceratops`](https://github.com/charliermarsh/ruff/issues/2056)
+plugin, and looking to the originating [Python source](https://github.com/guilatrova/tryceratops)
+for guidance. [`flake8-simplify`](https://github.com/charliermarsh/ruff/issues/998) has a few rules
+left too.
+
+### Prerequisites
+
+Ruff is written in Rust. You'll need to install the
+[Rust toolchain](https://www.rust-lang.org/tools/install) for development.
+
+You'll also need [Insta](https://insta.rs/docs/) to update snapshot tests:
+
+```shell
+cargo install cargo-insta
+```
+
+### Development
+
+After cloning the repository, run Ruff locally with:
+
+```shell
+cargo run resources/test/fixtures --no-cache
+```
+
+Prior to opening a pull request, ensure that your code has been auto-formatted,
+and that it passes both the lint and test validation checks.
+
+For rustfmt and Clippy, we use [nightly Rust][nightly], as it is stricter than stable Rust.
+(However, tests and builds use stable Rust.)
+
+```shell
+cargo +nightly fmt --all     # Auto-formatting...
+cargo +nightly clippy --fix --workspace --all-targets --all-features -- -W clippy::pedantic  # Linting...
+cargo test --all    # Testing...
+```
+
+These checks will run on GitHub Actions when you open your Pull Request, but running them locally
+will save you time and expedite the merge process.
+
+Your Pull Request will be reviewed by a maintainer, which may involve a few rounds of iteration
+prior to merging.
+
+### Example: Adding a new lint rule
+
+At a high level, the steps involved in adding a new lint rule are as follows:
+
+1. Create a file for your rule (e.g., `src/rules/flake8_bugbear/rules/abstract_base_class.rs`).
+2. In that file, define a violation struct. You can grep for `define_violation!` to see examples.
+3. Map the violation struct to a rule code in `src/registry.rs` (e.g., `E402`).
+4. Define the logic for triggering the violation in `src/checkers/ast.rs` (for AST-based checks),
+   `src/checkers/tokens.rs` (for token-based checks), `src/checkers/lines.rs` (for text-based
+   checks), or `src/checkers/filesystem.rs` (for filesystem-based checks).
+5. Add a test fixture.
+6. Update the generated files (documentation and generated code).
+
+To define the violation, start by creating a dedicated file for your rule under the appropriate
+rule linter (e.g., `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 `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 `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 +nightly dev print-ast` with a Python file. Grep
+for the `Check::new` invocations to understand how other, similar rules are implemented.
+
+To add a test fixture, create a file under `resources/test/fixtures/[linter]`, named to match
+the code you defined earlier (e.g., `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.
+
+Run `cargo +nightly dev generate-all` to generate the code for your new fixture. Then run Ruff
+locally with (e.g.) `cargo run resources/test/fixtures/pycodestyle/E402.py --no-cache --select E402`.
+
+Once you're satisfied with the output, codify the behavior as a snapshot test by adding a new
+`test_case` macro in the relevant `src/[linter]/mod.rs` file. Then, run `cargo test --all`.
+Your test will fail, but you'll be prompted to follow-up with `cargo insta review`. Accept the
+generated snapshot, then commit the snapshot file alongside the rest of your changes.
+
+Finally, regenerate the documentation and generated code with `cargo +nightly dev generate-all`.
+
+### Example: Adding a new configuration option
+
+Ruff's user-facing settings live in a few different places.
+
+First, the command-line options are defined via the `Cli` struct in `src/cli.rs`.
+
+Second, the `pyproject.toml` options are defined in `src/settings/options.rs` (via the `Options`
+struct), `src/settings/configuration.rs` (via the `Configuration` struct), and `src/settings/mod.rs`
+(via the `Settings` struct). These represent, respectively: the schema used to parse the
+`pyproject.toml` file; an internal, intermediate representation; and the final, internal
+representation used to power Ruff.
+
+To add a new configuration option, you'll likely want to modify these latter few files (along with
+`cli.rs`, if appropriate). If you want to pattern-match against an existing example, grep for
+`dummy_variable_rgx`, which defines a regular expression to match against acceptable unused
+variables (e.g., `_`).
+
+Note that plugin-specific configuration options are defined in their own modules (e.g.,
+`src/flake8_unused_arguments/settings.rs`).
+
+You may also want to add the new configuration option to the `flake8-to-ruff` tool, which is
+responsible for converting `flake8` configuration files to Ruff's TOML format. This logic
+lives in `flake8_to_ruff/src/converter.rs`.
+
+Finally, regenerate the documentation and generated code with `cargo +nightly dev generate-all`.
+
+## Release process
+
+As of now, Ruff has an ad hoc release process: releases are cut with high frequency via GitHub
+Actions, which automatically generates the appropriate wheels across architectures and publishes
+them to [PyPI](https://pypi.org/project/ruff/).
+
+Ruff follows the [semver](https://semver.org/) versioning standard. However, as pre-1.0 software,
+even patch releases may contain [non-backwards-compatible changes](https://semver.org/#spec-item-4).

+# flake8-to-ruff
+
+Convert existing Flake8 configuration files (`setup.cfg`, `tox.ini`, or `.flake8`) for use with
+[Ruff](https://github.com/charliermarsh/ruff).
+
+Generates a Ruff-compatible `pyproject.toml` section.
+
+## Installation and Usage
+
+### Installation
+
+Available as [`flake8-to-ruff`](https://pypi.org/project/flake8-to-ruff/) on PyPI:
+
+```shell
+pip install flake8-to-ruff
+```
+
+### Usage
+
+To run `flake8-to-ruff`:
+
+```shell
+flake8-to-ruff path/to/setup.cfg
+flake8-to-ruff path/to/tox.ini
+flake8-to-ruff path/to/.flake8
+```
+
+`flake8-to-ruff` will print the relevant `pyproject.toml` sections to standard output, like so:
+
+```toml
+[tool.ruff]
+exclude = [
+    '.svn',
+    'CVS',
+    '.bzr',
+    '.hg',
+    '.git',
+    '__pycache__',
+    '.tox',
+    '.idea',
+    '.mypy_cache',
+    '.venv',
+    'node_modules',
+    '_state_machine.py',
+    'test_fstring.py',
+    'bad_coding2.py',
+    'badsyntax_*.py',
+]
+select = [
+    'A',
+    'E',
+    'F',
+    'Q',
+]
+ignore = []
+
+[tool.ruff.flake8-quotes]
+inline-quotes = 'single'
+
+[tool.ruff.pep8-naming]
+ignore-names = [
+    'foo',
+    'bar',
+]
+```
+
+### Plugins
+
+`flake8-to-ruff` will attempt to infer any activated plugins based on the settings provided in your
+configuration file.
+
+For example, if your `.flake8` file includes a `docstring-convention` property, `flake8-to-ruff`
+will enable the appropriate [`flake8-docstrings`](https://pypi.org/project/flake8-docstrings/)
+checks.
+
+Alternatively, you can manually specify plugins on the command-line:
+
+```shell
+flake8-to-ruff path/to/.flake8 --plugin flake8-builtins --plugin flake8-quotes
+```
+
+## 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.)
+2. Ruff will omit any rule codes that are unimplemented or unsupported by Ruff, including rule
+   codes from unsupported plugins. (See the [Ruff README](https://github.com/charliermarsh/ruff#user-content-how-does-ruff-compare-to-flake8)
+   for the complete list of supported plugins.)
