 ### Enhancements
 
+- Improve color contrast of primary buttons and links.
 - Add Hindi localized UI text strings. [#1888](https://github.com/mmistakes/minimal-mistakes/pull/1888)
 - Update Lunr to `2.3.3`. [#1885](https://github.com/mmistakes/minimal-mistakes/pull/1885)
 - Cache "static" includes to improve build performance. **Note:** The theme uses the [jekyll-include-cache](https://github.com/benbalter/jekyll-include-cache) plugin which will need to be installed in your `Gemfile` and added to the `plugins` array of `_config.yml`. Otherwise you'll throw `Unknown tag 'include_cached'` errors at build. [#1874](https://github.com/mmistakes/minimal-mistakes/pull/1874)
