rstudio/bslib v0.10.0 on GitHub

Breaking changes

bslib now uses the {brand.yml} package for reading brand.yml files. This change improves compatibility with other tools that use brand.yml files, such as Quarto. The {brand.yml} package must be installed for _brand.yml files to be automatically discovered. (#1227)

Added a new input_submit_textarea() input element, which is similar to shiny::textAreaInput(), but includes a submit button to only submit the text changes to the server on click. This is especially useful when the input text change triggers a long-running operation and/or the user wants to type longer-form input and review it before submitting it. (#1204)
Added toast notifications based on Bootstrap's Toast component: Use toast() to create customizable toast objects, show_toast() to display a toast message, hide_toast() for manual dismissal, and toast_header() for structured headers with icons and status indicators. Try it with shiny::runExample("toast", package = "bslib"). (#1246)
Added a new input_code_editor() element that allows for light-weight code editing with syntax highlighting, using the prism-code-editor library. The editor supports 20+ languages, more than a dozen themes, and automatic light/dark mode switching. Try it with shiny::runExample("code-editor", package = "bslib"). (#1274)

card_header() is now flex by default and gains a gap argument to better support complex header layouts. (#1253)
bs_theme_dependencies() now avoids unnecessarily copying internal package files to R's temporary directory more than once when preparing precompiled theme dependencies (e.g. for a standard bs_theme() theme). (#1184)
Fixed an issue where the <main> areas of page_sidebar() and page_navbar() (with a sidebar) were made to be a fillable containers even when fillable = FALSE. (#1188)
Fixed some typos in the documentation.
When bs_theme(brand = FALSE) we now correctly do not apply brand theming when a _brand.yml file is present in the project. (#1196)
Sidebars from page_sidebar() and layout_sidebar() are now resizable on desktop-sized screen widths, allowing users to resize the sidebar width as desired. (#1217)
sidebar() gains a fillable argument to support vertical fill behavior in sidebars. (#1226)
sidebar_toggle() is now officially deprecated in favor of toggle_sidebar(). (#1235)
Fixed an issue where nav_panel_hidden() could create navs that were still keyboard-discoverable. (#1264)
