@@ -35,7 +35,7 @@ Key structure:
 - **Sending content on** - Content which leaves one place for another, such as the result of an assistant sent to another assistant or a text sent into the chat, travels as a `TextLaunchPayload` through `AssistantLaunchService`, together with the restrictions of where it was written (`ChatRestrictions`, see `ChatThread.CaptureRestrictions`). Never hand over a bare string: the destination would let any provider or tool see content which its source kept from them. Build the payload with `AssistantLaunchService.CreateTextPayloadAsync`, which filters what an AI wrote for prompt injections before it reaches the next model as a message of the user. An assistant which allows sending to it overrides `AssistantBase.ApplyTextLaunchPayload`, and `SendToReceiverTests` checks that every one does; the restrictions themselves are applied centrally in `AssistantBase`.
 - **JSON in model answers** - Read the JSON part of a model answer with `ModelAnswerJson`, never with a scanner of your own. It skips the prose and code fences around the JSON but checks nothing, so broken JSON reaches the deserializer unchanged and its message can go back to the model.
 - **Long menus** - MudBlazor keeps a `MudSelect` inside the window by itself, but never a `MudMenu`: a menu taller than the window runs past its edge, and its lower entries cannot be reached. Give every `MudMenu` whose entries come from data, such as the assistants or the profiles, `MaxHeight="@MenuDefaults.MAX_HEIGHT"`, so that it scrolls.
- **Growing popovers** - MudBlazor places an open popover only when it opens, when the window changes, and when its component renders again. Content which unfolds later, such as a `MudCollapse` or an `ExpansionPanel` inside a `MudPopover`, would therefore grow out of the window. `wwwroot/app.js` places every open popover again whenever its size changes, so such content needs no code of its own. This relies on `window.mudpopoverHelper.placePopoverByNode`, which is internal to MudBlazor: check that it still exists with every new MudBlazor version.
+- **Growing popovers** - Since version 9, MudBlazor places an open popover again whenever its content changes size. Content which unfolds later, such as a `MudCollapse` or an `ExpansionPanel` inside a `MudPopover`, therefore stays inside the window and needs no code of its own.
 - **Encryption** - Initialized before Rust service is marked ready
 - **Debug environment** - Reads `startup.env` file with IPC credentials
 - **Static files and the browser cache** - When the developer starts the app from Rider, the embedded browser of Tauri keeps the static files under `wwwroot/`, such as `app.css` or a script, in its cache. The app then still shows the old file, and a change seems not to work. Whenever you changed such a file, tell the developer to clear that cache through the developer tools of the embedded browser before testing. Users of a release are not affected.
