Update. Found this https://github.com/FortAwesome/Font-Awesome/wiki/Upgrading-from-3.2.1-to-4 - will try to follow.

Hi everybody,

Does someone have a link that shows the old names for the icons and new names for the font-awesome icons? Apparently, they renamed all the icons and I'm going to fix all our references in the application but this cheat sheet would be extremely helpful.

Thanks a lot in advance.
