* Add a `data-suggestion` attribute to an HTML element, and set the value to the input suggestion text (e.g., `<span data-suggestion="Suggestion value">Suggestion link</span>`)

* To auto-submit the suggestion when clicked by the user, include the `.submit` class or the `data-suggestion-submit="true"` attribute on the HTML element. Alternatively, use Cmd/Ctrl + click to auto-submit any suggestion or Alt/Opt + click to apply any suggestion to the chat input without submitting.

* Added a new `.add_sass_layer_file()` method to `ui.Theme` that supports reading a Sass file with layer boundary comments, e.g. `/*-- scss:defaults --*/`. This format [is supported by Quarto](https://quarto.org/docs/output-formats/html-themes-more.html#bootstrap-bootswatch-layering) and makes it easier to store Sass rules and declarations that need to be woven into Shiny's Sass Bootstrap files.

* The `.on_user_submit()` decorator method now passes the user input to the decorated function. This makes it a bit easier to access the user input. See the new templates (mentioned below) for examples. (#1801)
23
-
* A new `get_latest_stream_result()` method was added for an easy way to access the final result of the stream when it completes. (#1846)
21
+
* The assistant icon is now configurable via `ui.chat_ui()` (or the `ui.Chat.ui()` method in Shiny Express) or for individual messages in the `.append_message()` and `.append_message_stream()` methods of `ui.Chat()`. (#1853)
22
+
* A new `latest_message_stream` property was added for an easy way to reactively read the stream's status, result, and also cancel an in progress stream. (#1846)
24
23
* The `.append_message_stream()` method now returns the `reactive.extended_task` instance that it launches. (#1846)
24
+
* The `ui.Chat()` component's `.update_user_input()` method gains `submit` and `focus` options that allow you to submit the input on behalf of the user and to choose whether the input receives focus after the update. (#1851)

*`shiny create` includes new and improved `ui.Chat()` template options. Most of these templates leverage the new [`{chatlas}` package](https://posit-dev.github.io/chatlas/), our opinionated approach to interfacing with various LLM. (#1806)

* Client data values (e.g., url info, output sizes/styles, etc.) can now be accessed in the server-side Python code via `session.clientdata`. For example, `session.clientdata.url_search()` reactively reads the URL search parameters. (#1832)

*`ui.input_text()`,`ui.input_text_area()`, `ui.input_numeric()` and `ui.input_password()`all gain an `update_on` option. `update_on="change"` is the default and previous behavior, where the input value updates immediately whenever the value changes. With `update_on="blur"`, the input value will update only when the text input loses focus or when the user presses Enter (or Cmd/Ctrl + Enter for `ui.input_text_area()`). (#1874)

### Changes
42
+
* The navbar-related style options of `ui.page_navbar()` and `ui.navset_bar()` have been consolidated into a single `navbar_options` argument that pairs with a new `ui.navbar_options()` helper. Using the direct `position`, `bg`, `inverse`, `collapsible`, and `underline` arguments will continue to work with a deprecation message.
43
+
44
+
Related to this change, `ui.navset_bar()` now defaults to using `underline=True` so that it uses the same set of default `ui.navbar_options()` as the page variant. In `ui.navbar_options()`, `inverse` is replaced by `theme`, which takes values `"light"` (dark text on a **light** background), `"dark"` (light text on a **dark** background), or `"auto"` (follow page settings).
