+## Release v0.4.2
+
+Hello! We're back again with another small release. Like `v0.4.1`, this release is a [semver patch](https://semver.org/): it only includes bugfixes, and is fully backwards-compatible.
+
+The big highlight of this theme is fixing our light scheme code highlighting contrast issues; this was one of our most-requested features! This change is fully backwards-compatible; users can [opt-in to our old highlighting theme](https://just-the-docs.github.io/just-the-docs/docs/customization/#deprecated-legacy_light) by using `legacy_light` instead of `light`.
+
+As always, we'd love your feedback. [Open an issue](https://github.com/just-the-docs/just-the-docs/issues) or [start a discussion](https://github.com/just-the-docs/just-the-docs/discussions) for bug reports, feature requests, and any other feedback. Thanks for continuing to use Just the Docs!
+
+### Using Release `v0.4.2`
+
+Users who have not pinned the theme version will be **automatically upgraded to `v0.4.2` the next time they build their site**.
+
+To use this release explicitly as a remote theme:
+
+```yml
+remote_theme: just-the-docs/just-the-docs@v0.4.2
+```
+
+To use this RC explicitly as a gem-based theme, pin the version in your `Gemfile` and re-run `bundle install` or `bundle update just-the-docs`:
+
+```ruby
+gem "just-the-docs", "0.4.2"
+```
+
+To use and pin a previous version of the theme, replace the `0.4.2` with the desired release tag.
+
