Alexandrite now has cross-posting! You can cross post from the '...' menu on posts:

You then pick a community from your subscriptions, or search for any other community, or directly enter the full name like alexandrite@lemmy.world if you want a very specific one and don't want to bother with searching.

And links to cross-posts will now show when viewing a posts:

Alexandrite now matches Lemmy-UI handling taglines. If an instance has any taglines set it will now pick a random one instead of showing all of them.

Lastly if you have NSFW thumbnail handling set to "Hide" or "Blur", it will now hide/blur thumbnails when a post is in a NSFW community, even if the post itself isn't marked NSFW, as the post is probably actually NSFW anyway and it's better to be safe than sorry.
