Mastodon 4.5 brings Quote Post authoring features to everyone. Note that you can manage whether or how your posts are quoted by others, both globally on the new Posting Defaults page, and individually on specific posts. You can also revoke the use of a post. We wrote about this in more detail a few weeks ago: https://blog.joinmastodon.org/2025/09/introducing-quote-posts/
Introducing quote posts

Over the years, we’ve learned just how essential quoting is to many of you. Here's a deep dive on how quote posts will work on Mastodon.

The Fediverse feels more vibrant when conversations are buzzing! Mastodon 4.5 fetches replies from other servers to show you more complete conversation threads - another much-anticipated feature.
@Mastodon better late than never! I am so glad to see this bug finally fixed, and I hope it presages future use of the full feature set of ActivityPub.
@evan @Mastodon this is definitely the most impactful new feature after QPs! Have noticed a dramatic difference in counts
@chris @Mastodon Let's hope that loading an actor's `outbox` to show their existing posts is next! 🤞🏼
@evan @chris @Mastodon Jonny is trying. His backfill PR has been ignored for 6 months (due to focus on quotes)
