An over-the-ceiling viewer is now turned away before anything is written, and everyone already watching carries on undisturbed. Take this one if you use multi-use links.",

The create popup has a new \"Let several people use this link\" box: tick it and the link keeps working for everyone you send it to until it expires. It is a per-link choice now, and the old plugin setting is just what the box starts out as. Multi-use links have a ceiling on how many people can watch at once, ten by default and configurable; anyone arriving after that is asked to try again later and nobody already watching is disturbed. Multi-use did not actually work before this release: guests were capped at one session, so the second viewer's redemption failed and cleanup then deleted the guest account out from under the first viewer.",
