Can you release the latest version of Fontawesome into dev?
@zuzuzuzz There is an official alternative to try until Shiny proper gets a Fontawesome update. The option is to use the fontawesome package. It works well in Shiny, and it's updated to the latest free icons. The README (with a Shiny example) is at: https://github.com/rstudio/fontawesome.
If you need icons in your valuebox you can do this:
infoBox(
"title",
"value",
icon = tags$i(fa(name = "box", fill = "white")),
color = "teal", fill =TRUE, width = 3
)

Thanks @rich-iannone. This save my day. Hovewer, it doesn't work on Microsft IE11.
I'm using your suggeted alternative to display icon in my shinydashboard sidebar. It works fine with Chrome, Firefox and Edge. But on IE11 it only shows the icon instead of icon + menu item title.
Do you have any idea to fix this issue?
At least, can we have menu item title displayed?
Using icon = tags$i(fa(name = "box", fill = "white")), isn't a great solution for icons in the menu bar because it doesn't pick up the proper styling. i.e. the icon is set at one color and not highlighted properly when selected or not selected. Also the spacing between the icon and the menu item name is off.

Thanks for your patience. We've upgraded FA in Shiny on master, since the separate Font Awesome package raised more questions than we expected.
Please raise issues on the rstudio/fontawesome repo if you have problems with that package.
I'm closing this because the FA upgrade went out with Shiny 1.2, but feel free to re-open or make another issue if your needs remain unmet.
