What
Artifacts (the standalone documents, apps, or games Claude can create and show alongside a conversation) can now be republished with updates that reach any viewers already open, without the reader having to reopen or refresh them.
Where possible, the update carries over the current state of the page, such as a game in progress, a queued action, or a reply that has been half-typed but not sent.
Why
This means updating an artifact no longer risks losing what someone was doing in it, so iterating on an open artifact is safer and less disruptive.
