Which Jekyll plugins are whitelisted by GitHub Pages?

Question

I heard somewhere that GitHub pages support a small number of white-listed Jekyll plugins, yet I can't seem to find a comprehensive list anywhere.

Where can this information be found?

Answer 1

Here's a list with the Jekyll plugins that GitHub Pages support:

https://pages.github.com/versions/

Answer 2

I’d like to add that the link Red provided may be outdated when more plugins get whitelisted.

github/pages-gem: plugins.rb should be up to date.
