Upgrade notes for Shiny 1.7.0

Full changelog

Breaking changes

  • The format and locale arguments to sliderInput() have been removed. They have been deprecated since (released on 2014-12-08).

  • Closed #3403: insertTab()’s position parameter now defaults to "after" instead of "before". This has the benefit of allowing us to fix a bug in positioning when target = NULL, but has the drawback of changing the default behavior when target is not NULL. (#3404)

New features and improvements

  • Bootstrap 5 support. (#3410 and rstudio/bslib#304)
    • As explained here, to opt-in to Bootstrap 5, provide bslib::bs_theme(version = 5) to a page layout function with a theme argument (e.g., fluidPage(), navbarPage(), etc).
  • Closed #3322, #3313, #1823, #3321, #3320, #1928, and #2310: Various improvements to navbarPage(), tabsetPanel(), tabPanel(), navbarMenu(), etc. Also, these functions are now powered by the {bslib} package’s new nav() API (consider using {bslib}’s API to create better looking and more fully featured navs). (#3388)

  • All uses of list(...) have been replaced with rlang::list2(...). This means that you can use trailing , without error and use rlang’s !!! operator to “splice” a list of argument values into .... We think this’ll be particularly useful for passing a list of tabPanel() to their consumers (i.e., tabsetPanel(), navbarPage(), etc). For example, tabs <- list(tabPanel("A", "a"), tabPanel("B", "b")); navbarPage(!!!tabs). (#3315 and #3328)

  • installExprFunction() and exprToFunction() are now able to handle quosures when quoted = TRUE. So render-functions which call these functions (such as with htmlwidgets) can now understand quosures. Users can also use rlang::inject() to unquote a quosure for evaluation. This also means that render function no longer need env and quoted parameters; that information can be embedded into a quosure which is then passed to the render function. Better documentation was added for how to create render functions. (#3472)

  • icon(lib="fontawesome") is now powered by the {fontawesome} package, which will make it easier to use the latest FA icons in the future (by updating the {fontawesome} package). (#3302)

  • Closed #3397: renderPlot() new uses ggplot2::get_alt_text() to inform an alt text default (for {ggplot2} plots). (#3398)

  • modalDialog() gains support for size = "xl". (#3410)

  • Addressed #2521: Updated the list of TCP ports that will be rejected by default in runapp.R, adding 5060, 5061 and 6566. Added documentation describing the port range (3000:8000) and which ports are rejected. (#3456)

Other improvements

  • Shiny’s core JavaScript code was converted to TypeScript. For the latest development information, please see the README.md in ./srcts. (#3296)

  • Switched from digest::digest() to rlang::hash() for hashing. (#3264)

  • Switched from internal Stack class to fastmap::faststack(), and used fastmap::fastqueue(). (#3176)

  • Some long-deprecated functions and function parameters were removed. (#3137)

Bug fixes

  • Closed #3345: Shiny now correctly renders htmltools::htmlDependency()(s) with a list() of script attributes when used in a dynamic UI context. This fairly new htmlDependency() feature was added in {htmltools} v0.5.1. (#3395)

  • Fixed #2666 and #2670: nearPoints() and brushedPoints() weren’t properly account for missing values (#2666 was introduced in v1.4.0). (#2668)

  • Closed #3374: quoToFunction() now works correctly with nested quosures; and as a result, quasi-quotation with rendering function (e.g., renderPrint(), renderPlot(), etc) now works as expected with nested quosures. (#3373)

  • Exported register_devmode_option(). This method was described in the documentation for devmode() but was never exported. See ?devmode() for more details on how to register Shiny Developer options using register_devmode_option(). (#3364)

  • Closed #3484: In the RStudio IDE on Mac 11.5, selected checkboxes and radio buttons were not visible. (#3485)

Library updates

  • Closed #3286: Updated to Font-Awesome 5.15.2. (#3288)

  • Updated to jQuery 3.6.0. (#3311)
