* Both `ui.Chat()` and `ui.MarkdownStream()` now support arbirary Shiny UI elements inside of messages. This allows for gathering input from the user (e.g., `ui.input_select()`), displaying of rich output (e.g., `render.DataGrid()`), and more. (#1868)

* Added a new `.message_stream_context()` method to `ui.Chat()`. This context manager is a useful alternative to `.append_message_stream()` when you want to: (1) Nest a stream within another and/or
(2) Overwrite/replace streaming content. (#1906)

### Changes

* Express mode's `app_opts()` requires all arguments to be keyword-only. If you are using positional arguments, you will need to update your code. (#1895)
