Ok, I think the new ones in version 4.4 are not updated. You can probably request shiny team to update them and they will do it very easily. Alternatively you can do it yourself by downloading them and replacing the previous content...

1. Go to the Font Awesome download page and get it

2. Locate your font awesome folder where you installed shiny package. This should be somewhere like here ~\Documents\R\win-library\3.1\shiny\www\shared\font-awesome

3. Replace the content of this folder with new contents (you can delete the previous content if you want). Below is what I put in there

4. Now your app should work fine with new fonts

This is an older question, but the issue remains for me in July 2020. I found the solution in the github issues page. The trick is to make sure you are looking at the library of icons in the version of Font Awesome Shiny is calling. Currently (again, July 2020) the version is 4.7. All of these icons currently work.

Another option is to call the version of fontawesome you want using the following code within your app's ui function (this solution originally posted here):

tags$style("@import url(https://use.fontawesome.com/releases/v5.7.2/css/all.css);")

For me, in oct/2020, solution was adding a "s" after first "fa", as in fa fa-caret-up to fas fa-caret-up since it's the new sintax for font awesome icons.
