Seeking guidance on updating our project to use the latest Macadmine theme. The transition from Font Awesome 3 to Font Awesome 4 requires changing all icons to their proper names. I came across a helpful resource at https://github.com/FortAwesome/Font-Awesome/wiki/Upgrading-from-3.2.1-to-4, but I'm unsure about what to use for icon-1x. Many i tags have two icons defined, with the second being icon-1x. What should this be changed to?
