@nicOwlas Code is OK to be merged. Just let me know once you've finished our first announcement (of type warning 😉 ) and I'll deploy the PR on production.

The announcement is done. If you want to review it, it's here: https://announcekit.app/dashboard/post
If it's good, then go for merge!

@nicOwlas I've reviewed the post: I'd add a warning-sign emoji (⚠️) in the title but it's not a blocking point so I'll merge the PR once the CI is OK. Other than that, it looks good to me 👍

@Jordanlelay I've just removed the announcement code from /website (since the filter problem described in announcekitapp/announcekit-react#28 is not yet fixed). I've made a single commit with the changes if you want to review them quickly: 96069fb
