How to upgrade fontawesome version in so-widgets-bundle ?

Hi all,

Before all, please notice that i’m french so my English are not so rich.

Concerning my issue, i need to use an icon from fontawesome 4.6 and i don’t know how to update “features widget” of “so-widgets-bundle” font awesome library.

Someone can help me? Even for a temporary solution.

Regards.
