Breaking changes

bs_theme() now defaults to version = 5 (i.e., Bootstrap 5). If this change happens to break an existing app, consider specifying bs_theme(version = 4) to revert the change in the Bootstrap version. (#374)
The default coloring on some Bootswatch 4+ theme's .navbar-default/.navbar-inverse class has changed slightly to better match their Bootswatch 3 coloring. Also, since this coloring is now based solely on $navbar-* variables, Bootswatch themes now work better in combination with custom $navbar-* values (e.g., bs_theme("navbar-bg" = ...) can be used to provide the background color, and foreground colors will automatically contrast appropriately). (#392)

Upgraded Bootstrap 5 (i.e., bs_theme(version = 5)) from 5.1.0 to 5.1.3 (#378)
Closed #369: bs_dependency_defer() now memoises func (by default), reducing the time required to render multiple instances of the same dynamically themable widget. (#405)

Closed #393: Bootstrap 5's $form-check-label-* variables now work as expected with shiny::radioButtons(), shiny::checkboxInput(), and shiny::checkboxGroupInput(). (#395)
Closed #382: Various fixes for using shiny::checkboxInput(), shiny::checkboxGroupInput(), and shiny::radioButton() with bs_theme(version = 5, bootswatch = "sketchy"). (#385)
Closed #377: make sure shiny::tabsetPanel(type = "hidden") (i.e., bslib::navs_hidden()) stays hidden when used with bs_theme(). (#379)
Closed #424: fixed an issue with nav_menu() appearing first in a navs_*() container with Bootstrap 4+.
Closed #431: Bootstrap 5 navbars no longer have an unwanted "Toggle Navigation" label when collapsed. (#432)
Closed #400: nav_menu(align="right") now works with Bootstrap 5. (#401)
Closed #390: using bs_theme(bootswatch = "paper", version = 5) or bs_theme(bootswatch = "readable", version = 5) no longer errors. (#391)
