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 0.10.2.2 (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)
