+#### The `release_commits` field
+
+In `release-plz update` and `release-plz release-pr`, `release-plz` bumps the version and updates the changelog
+of the package only if at least one of the commits matches the `release_commits` regex.
+
+You can use this if you think it is too noisy to raise PRs on every commit.
+
+Examples:
+
+- With `release_commits = "^feat:"`, release-plz will update the package only if there's a new feature.
+- With `release_commits = "^(feat:|docs:)"`, release-plz will update the package only if there's a new feature or a documentation change.
+
+By default, release-plz updates the package on every commit.
+
+:::warning
+The filtered commits are still included in the changelog.
+To exclude certain commits from the changelog, use the [commit_parsers](#the-commit_parsers-field) field.
+:::

 #### The `repo_url` field
 
 GitHub/Gitea repository URL where your project is hosted.
