@LisaFC and @raum51 could you have a look at this one? Fontawesome 6 would be very good to have by default, instead of us having to work around and add it manually. It looks like there's a Docsy release planned for fall, and we'd love to help get this into that.

[LisaFC]

Will take a look - @chalin, can you take a look as well? Agree would be good to have the latest version for the next Docsy release. It doesn't look like it's likely to break anything but do FontAwesome themselves document any breaking changes? Don't want any users to suddenly end up with unexpected icons.

[chalin]

Will take a look as soon as I can. Please rebase & resolve the conflicts, thanks.

@chalin conflicts resolved.

Backward compatibility information from the project: https://fontawesome.com/docs/web/setup/upgrade/whats-changed#backward-compatibility

Lots of icons got renamed, but the v5 names will still work. It'd be worth pointing to this table in the release notes, though, to make people aware that they should pick up the new names at some point.

Thanks @samiahmedsiddiqui for the PR. Thanks @polarweasel for the link to the backwards compatibility page.

FYI, some prep work which I'd like reviewed and merged before this PR:
