 # Breaking Changes
 
-## 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.
-
 ## 0.1.0
 
 ### The deprecated `format` setting has been removed

 ### 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.
-1. Create a pull request with the changelog and version updates
+1. Update the version with `rg 0.0.269 --files-with-matches | xargs sed -i 's/0.0.269/0.0.270/g'`
+1. Update `BREAKING_CHANGES.md`
+1. Create a PR with the version and `BREAKING_CHANGES.md` updated
 1. Merge the PR
-1. Run the [release workflow](https://github.com/astral-sh/ruff/actions/workflows/release.yaml) with:
-    - The new version number (without starting `v`)
-    - The commit hash of the merged release pull request on `main`
+1. Run the release workflow with the version number (without starting `v`) as input. Make sure
+    main has your merged PR as last commit
 1. The release workflow will do the following:
     1. Build all the assets. If this fails (even though we tested in step 4), we haven't tagged or
         uploaded anything, you can restart after pushing a fix.
     1. Upload to PyPI.
     1. Create and push the Git tag (as extracted from `pyproject.toml`). We create the Git tag only
-        after building the wheels and uploading to PyPI, since we can't delete or modify the tag ([#4468](https://github.com/astral-sh/ruff/issues/4468)).
+        after building the wheels and uploading to PyPI, since we can't delete or modify the tag ([#4468](https://github.com/charliermarsh/ruff/issues/4468)).
     1. Attach artifacts to draft GitHub release
     1. Trigger downstream repositories. This can fail non-catastrophically, as we can run any
         downstream jobs manually if needed.
-1. Publish the GitHub release
-    1. Open the draft release in the GitHub release section
-    1. Copy the changelog for the release into the GitHub release
-        - See previous releases for formatting of section headers
-    1. Generate the contributor list with `rooster contributors` and add to the release notes
-1. If needed, [update the schemastore](https://github.com/astral-sh/ruff/blob/main/scripts/update_schemastore.py).
-    1. One can determine if an update is needed when
-        `git diff old-version-tag new-version-tag -- ruff.schema.json` returns a non-empty diff.
-    1. Once run successfully, you should follow the link in the output to create a PR.
+1. Create release notes in GitHub UI and promote from draft.
+1. If needed, [update the schemastore](https://github.com/charliermarsh/ruff/blob/main/scripts/update_schemastore.py)
