 # 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))
