+## Release v0.5.1
+
+Hi all, this is a very small minor patch release that has two small behavioral bugfixes: fixing a regression introduced in `v0.5.0` on Safari versions `<16.4` (broken media query), and the copy code button providing incorrect feedback in insecure browser contexts. This should be a smooth upgrade with no breaking changes.
+
+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 `v0.5.1`
+
+Users who have not pinned the theme version will be **automatically upgraded to `v0.5.1` 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@v0.5.1
+```
+
+To use this version 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", "0.5.1"
+```
+
+To use and pin a previous version of the theme, replace the `0.5.1` with the desired release tag.
