I summarized this:
The result:
This discussion is about which version of Font Awesome the Category Icons plugin for Discourse uses.
TechnoFox ([1][/t/-/277694]) asked what version Category Icons uses, wondering if an upgrade is possible. Firepup650 ([2][/t/-/277694]) responded that Discourse overall uses FontAwesome 5, so upgrading Category Icons alone would require changes to other parts of Discourse.
TechnoFox ([3][/t/-/277694]) followed up by asking if there are any plans to update Discourse to newer FontAwesome versions, and what might be preventing that.
Finally, pfaffman ([4][/t/-/277694]) linked to a meta post indicating Discourse has introduced FontAwesome 5 and SVG icons.
The links aren’t properly formatted. It wrapped the link with square brackets instead of brackets.

should be ([1](/t/-/277694))
