Thanks for your contribution 🙌

• This change will require a changeset like this one to inform our users about the new icon (you can generate one using the pnpm exec changeset command)
• Would you mind reverting the changes to non-English doc pages that were introduced and only keep the changes for the English version? We usually only update the English pages and leave changes to the translations to our translators as this makes it easier for the Starlight translation tracker to keep track of the changes.

[mehalter]

Sure no problem @HiDeoo ! I have updated my commit to add the changeset and remove the international updates.

[HiDeoo]

Thanks for the update, this looks good to me 🙌

[delucis]

Thanks for adding this @mehalter! Added one suggestion but other than that, this looks great and we can get it out in our next patch release.

[delucis]

Thanks! Should be good to go for our next release 🙌

We’ll merge it shortly before release to avoid updating the docs site until the Reddit icon is available.

[mehalter]

Awesome sounds great! @delucis I also went ahead and looked at optimizing the rest of the UI icons in that file as some of them are much larger than they need to be. I went ahead and opened another PR. Let me know if this is something you are interested in or if you would prefer it be in this PR as well.

[delucis]

Nice that’s very helpful — thanks @mehalter. A separate PR makes sense for that I think 🙌

[mehalter]

With that other large change to the Icons.ts file git wasn't smart enough to resolve the diff so I went ahead and did a rebase on the current main.

Thanks for letting me make some small contributions. Great job on this project, it is awesome!

[delucis]

Thanks for resolving those — looks good!
