shiny 1.5.0 on Python PyPI

Added AI-powered test generator for Shiny applications. Use shiny add test to automatically generate comprehensive Playwright tests for your apps using AI models from Anthropic or OpenAI. (#2041)
ui.sidebar() is now interactively resizable. (#2020)
ui.sidebar() gains a fillable argument to support vertical fill behavior in sidebars. (#2077)
Added ui.insert_nav_panel(), ui.remove_nav_panel(), and ui.update_nav_panel() to support dynamic navigation. (#90)
navset_card_*() now gains a full_screen option. (#1451)
ui.update_*() functions now accept ui.TagChild (i.e., HTML) as input to the label and icon arguments. (#2020)
The .output_*() methods of the ClientData class (e.g., session.clientdata.output_height()) can now be called without an id when called inside a @render function. (#1978)
playwright.controller.InputActionButton gains a expect_icon() method. As a result, the already existing expect_label() no longer includes the icon. (#2020)

The ui.Chat and ui.MarkdownStream components are now imported from the new shinychat library. Future versions of shinychat will likely deprecate and remove some features from Chat. If you still want to use those features with the latest Shiny, we suggest pinning shinychat to it's initial release (v0.1.0). (#2051)
express.ui.insert_accordion_panel()'s function signature has changed to be more ergonomic. Now you can pass the panel_title and panel_contents directly instead of ui.hold()ing the ui.accordion_panel() context manager. (#2042)

Improved the styling and readability of markdown tables rendered by ui.Chat() and ui.MarkdownStream(). (#1973)
input_date(), input_date_range(), update_date(), and update_date_range() now support "" for values, mins, and maxes. In this case, no date will be specified on the client. (#1713) (#1689)
Restricted the allowable types of the choices parameter of input_select(), input_selectize(), update_select(), and update_selectize() to actual set of allowable types (previously, the type was suggesting HTML-like values were supported). (#2048)
Added module support for session.clientdata methods. This allows you to access client data values in Shiny modules without needing to namespace the keys explicitly. (#1978)
Added timeout_secs parameter to create_app_fixture to allow testing apps with longer startup times. (#2033)
Add support for selecting menu items in Navset controllers to improve dropdown navigation test coverage. (#2066)
Python 3.13 is now offically supported and tested. (#1711)

Fixed issue where apps run in Workbench were unexpectedly crashing. Apps running in Workbench will now have ws_per_message_deflate=False enforced. (#2005)
include_js() and include_css() now work as expected in multi-user settings and also when multiple files from the same directory are included. (#2061, #2069)
Fixed numerous issues related to programmatically updating selectize options. (#2053)
- update_selectize(options=...) no longer gets ignored when server=False (the default).
- update_selectize(options=...) now works as expected in a module.
Fixed an issue with update_selectize(server=True) not properly displaying labels with HTML reserved characters like "&" (#1330)
Fixed an issue with ui.Chat() sometimes wanting to scroll a parent element. (#1996)
Fix several issues with bookmarking error reporting and documentation. (#2076, #1984, #1983)
input_date() and input_date_range() once again use the client's (not the server) current date as the default value. (#2060)
Fixed false positive warning in layout_columns() about number of widths vs elements. (#1704)
Fixed set() method of the InputSelectize test controller so it clears existing selections before applying new values. (#2024)

ui.update_navs() is deprecated in favor of ui.update_navset(). (#2047)
ui.panel_well() is deprecated in favor of ui.card(). (#2038)
selectize, remove_button, and options parameters of ui.input_select() have been deprecated; use ui.input_selectize() instead. (Thanks, @ErdaradunGaztea!) (#1947)
