Font Awesome icon version outdated
I noticed Vivaldi Forum uses an outdated version of font awesome. If I'm correct the version used is 3.1 and font awesome is already at 5.0. Update if you find the time?
Vivaldi fetches https://forum.vivaldi.net/assets/vendor/fontawesome/fonts/fontawesome-webfont.woff2?v=4.7.0
That's strange. I tried to use a couple of icons from version 4.0 and they didn't load -- not a single one. And I made sure they were "free" not "pro".
Ok, I think I know what's going on. I was able to load an icon from version 4.7. The problem is that they present icons as free on their website, which aren't free. They dropped the fa class in favor of fas, fab, far and fal, and only fas and fab are free. But if you select to show only free icons, far and fal icons will still show. A pretty big mess up on their end.
Well, I will continue testing this. Not 100% sure about all of this.
