Discord embeds for Mastodon posts are getting a lot better! You should see better images and videos, better formatting, better context styling, and support for embedding a wider variety of posts. This is rolling out now, so you should see it start to take effect in the coming hours. Let me know if you run into any problems!

@rcombs how well does this work with non-masto fedi software (*key, iceshrimp.net, akkoma etc)

@oli @rcombs I'm very curious too, since usually in third-party stuff people only implement Mastodon's own extensions and whatnot…

@mia @oli currently it only supports software that implements the mastodon API; I intend to roll out support for other ActivityPub software in the near future, but that'll only work with services that:
- provide a <link rel=alternate type=application/activity+json>
- respond to that endpoint without requiring auth

which turns out to be, like, 3 things! if you want stuff to embed from activitypub data, tell your server operators to inform embedders that it exists, and to let them read it

@rcombs the application/activity+json endpoint is what's used for federation so it can't be authenticated but many instances will require the request be signed to allow enforcing moderation actions
activitypub request signing unfortunately ossified around outdated drafts, see this W3C report for a summary of what you need to do (and this shell script i wrote for a minimal implementation)
i haven't used it but the aptly-named sigh crate is a reasonable-looking rust implementation of this

@rcombs i do hope this is implemented soon, i was very excited to see well-formatted activitypub embeds but there's no need for them to conflict with fairly common privacy protections for users
