+#### Removed x-only builtin tags
+During development of Storybook [Tags](https://storybook.js.org/docs/writing-stories/tags), we created `dev-only`, `docs-only`, and `test-only` built-in tags. These tags were never documented and superseded by the currently-documented `dev`, `autodocs`, and `test` tags which provide more precise control. The outdated `x-only` tags are removed in 10.0.
