 # Breaking Changes

-## 0.3.0
-
-### Ruff 2024.2 style
-
-The formatter now formats code according to the Ruff 2024.2 style guide. Read the [changelog](./CHANGELOG.md#030) for a detailed list of stabilized style changes.
-
-### `isort`: Use one blank line after imports in typing stub files ([#9971](https://github.com/astral-sh/ruff/pull/9971))
-
-Previously, Ruff used one or two blank lines (or the number configured by `isort.lines-after-imports`) after imports in typing stub files (`.pyi` files).
-The [typing style guide for stubs](https://typing.readthedocs.io/en/latest/source/stubs.html#style-guide) recommends using at most 1 blank line for grouping.
-As of this release, `isort` now always uses one blank line after imports in stub files, the same as the formatter.
-
-### `build` is no longer excluded by default ([#10093](https://github.com/astral-sh/ruff/pull/10093))
-
-Ruff maintains a list of directories and files that are excluded by default. This list 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`
- `dist`
- `node_modules`
- `site-packages`
- `venv`
-
-Previously, the `build` directory was included in this list. However, the `build` directory tends to be a not-unpopular directory
-name, and excluding it by default caused confusion. Ruff now no longer excludes `build` except if it is excluded by a `.gitignore` file
-or because it is listed in `extend-exclude`.
-
-### `--format` is no longer a valid `rule` or `linter` command option
-
-Previously, `ruff rule` and `ruff linter` accepted the `--format <FORMAT>` option as an alias for `--output-format`. Ruff no longer
-supports this alias. Please use `ruff rule --output-format <FORMAT>` and `ruff linter --output-format <FORMAT>` instead.
-
-## 0.1.9
-
-### `site-packages` is 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-rewrite`
- `.git`
- `.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`
- `site-packages`
- `venv`
-
-Previously, the `site-packages` directory was not excluded by default. While `site-packages` tends
-to be excluded anyway by virtue of the `.venv` exclusion, this may not be the case when using Ruff
-from VS Code outside a virtual environment.

-
-This release introduces the Ruff 2024.2 style, stabilizing the following changes:

- Add a blank line after nested classes with a dummy body (`...`) in typing stub files ([#9155](https://github.com/astral-sh/ruff/pull/9155))
- Reduce vertical spacing for classes and functions with a dummy (`...`) body ([#7440](https://github.com/astral-sh/ruff/issues/7440), [#9240](https://github.com/astral-sh/ruff/pull/9240))
- Add a blank line after the module docstring ([#8283](https://github.com/astral-sh/ruff/pull/8283))

 ### Creating a new release

-We use an experimental in-house tool for managing releases.
-
-1. Install `rooster`: `pip install git+https://github.com/zanieb/rooster@main`
-1. Run `rooster release`; this command will:
-    - Generate a changelog entry in `CHANGELOG.md`
-    - Update versions in `pyproject.toml` and `Cargo.toml`
-    - Update references to versions in the `README.md` and documentation
-1. The changelog should then be editorialized for consistency
-    - Often labels will be missing from pull requests they will need to be manually organized into the proper section
-    - Changes should be edited to be user-facing descriptions, avoiding internal details
-1. Highlight any breaking changes in `BREAKING_CHANGES.md`
-1. Run `cargo check`. This should update the lock file with new versions.

+
+### 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.)
+1. Ruff will omit any rule codes that are unimplemented or unsupported by Ruff, including rule
+    codes from unsupported plugins. (See the
+    [documentation](https://docs.astral.sh/ruff/faq/#how-does-ruff-compare-to-flake8) for the complete
+    list of supported plugins.)

 # Ruff Benchmarks

-The `ruff_benchmark` crate benchmarks the linter and the formatter on individual files:
-
-```shell
-# Run once on the "baseline".
-cargo bench -p ruff_benchmark -- --save-baseline=main
-
-# Compare against the "baseline".
-cargo bench -p ruff_benchmark -- --baseline=main
-
-# Run the lexer benchmarks.
-cargo bench -p ruff_benchmark lexer -- --baseline=main
-```
+The `ruff_benchmark` crate benchmarks the linter and the formatter on individual files.
