It's got a few additions/modifications:
- You can log in to a Mastodon, Bluesky, or Nostr account on Agora and it'll pull in your following/followers list from that account, while still allowing you to view/interact with posts from the other 2 protocols using bridges behind the scenes.
- "For You" tab that uses the open source FediAlgo library to discover interesting posts you haven't seen, based on which accounts you and your follows interact with.
- Search page also has a "suggested friends" feature that integrates the open source FollowGraph library. It looks up all the people you follow, and then the people they follow. Then it sorts them by the number of mutuals, or otherwise by how popular those accounts are.
- Integrated bridges into the search, so that if you search for a Bluesky handle like aoc.bsky.social or a nostr users hex code, it'll automatically know to use the relevant bridge for those protocols and find the bridged profile.
- When you follow a hashtag like #linux, it'll automatically follow the corresponding Lemmy community for that topic in your feed.
- Automatically loads your instance's version of a post so that you can like/boost/comment on it without having to think about what instance it's on.
