+## 2026-10-08 — One remote-desktop notice for every operator, and clearer wording `agent 0.36.0` `api 0.122.0`
+
+When two operators connect to the same Windows session, the person at the machine now sees one notice
+instead of two stacked ones. It names each operator on a line of its own, followed by your
+organization's sentence once. An operator joins the notice when they start watching, after the person
+allowed it under *Ask first*, and their line goes when they disconnect. If the session showing the
+notice ends first, the other one shows its own notice straight away and pauses its picture until that
+notice is up. Operators connected to different Windows sessions, such as two users on a Remote Desktop
+Services host, still get one notice each, on their own screen.
+
+The notice also says what is really happening. It reads "Antoine is remotely viewing and controlling
+this machine." rather than "… controlling this screen.", and "… is remotely viewing this machine's
+screen." for an operator who can only watch, in English, French and German.
+
+Update the agent release image and the API image. The wording comes with the API, the single notice
+with the agent. No web console or database update is required.
