GitHub Pages will upgrade to Jekyll 3.2 on August 23rd.

The upgrade to Jekyll 3.2 comes with over 100 improvements including the introduction of themes, meaning that soon, you’ll be able to create a beautiful site in minutes by simply adding theme: my-awesome-theme to your site’s config, without needing to copy styles or templates into your site’s repository.

This should be a seamless transition for all GitHub Pages users, but if you have a particularly complex Jekyll site, we recommend building your site locally with the latest version of Jekyll 3.2.x prior to August 23rd to ensure your site continues to build as expected.

For more information, see the Jekyll changelog and if you have any questions, we encourage you to get in touch with us.
