Font Awesome – New version not working

Hi,

I have updated the font awesome library to the latest one and trying to use some new icons from fa library.
But, none of them are coming up.

I have replaced the files in these locations :-

1) \wp-content\themes\cian\resources\js\font-awesome\[all folders with new one]
2) \wp-content\themes\cian\resources\lib\font-awesome\[all folders with new one]

Downloaded the new version from here :- https://github.com/FortAwesome/Font-Awesome

I restarted my local serve. and now when I go to pages \ features and try to use these new fonts, I am not seeing them.

Do I need to change anywhere else too.
