Updated Font Awesome version for template/field icons

[snobjorn 62]

Currently version 4.7.0 of Font Awesom is used in ProcessWire for icons for templates and fields. Since its release, both version 5 have come – and version 6 is in the making. I would like to see a newer version in the future in ProcessWire, @ryan

4.7.0 (in ProcessWire) has around 675 icons as far as I can tell. The current Font Awesome version has around 1600 icons. When version 6 comes, theres around 2200 icons I have read.
