-===========

+=======
 
-## Full changelog
-
-### Breaking changes
-
-### New features
-
-* `runTests()` is a new function that behaves much like R CMD check. `runTests()` invokes all of the top-level R files in the tests/ directory inside an application, in that application's environment. ([#2585](https://github.com/rstudio/shiny/pull/2585))
-
-* `testServer()` and `testModule()` are two new functions for testing reactive behavior inside server functions and modules, respectively. ([#2682](https://github.com/rstudio/shiny/pull/2682), [#2764](https://github.com/rstudio/shiny/pull/2764))
-
-* The new `moduleServer` function provides a simpler interface for creating and using modules. ([#2773](https://github.com/rstudio/shiny/pull/2773))
-
-* Resolved [#2732](https://github.com/rstudio/shiny/issues/2732): `markdown()` is a new function for writing Markdown with Github extensions directly in Shiny UIs. Markdown rendering is performed by the [commonmark](https://github.com/jeroen/commonmark) package. ([#2737](https://github.com/rstudio/shiny/pull/2737))
-
-### Minor new features and improvements
-
-* Fixed [#2042](https://github.com/rstudio/shiny/issues/2042), [#2628](https://github.com/rstudio/shiny/issues/2628): In a `dateInput` and `dateRangeInput`, disabled months and years are now a lighter gray, to make it easier to see that they are disabled. ([#2690](https://github.com/rstudio/shiny/pull/2690))
-
-* `getCurrentOutputInfo()` previously threw an error when called from outside of an output; now it returns `NULL`. ([#2707](https://github.com/rstudio/shiny/pull/2707))
-
-* Added a label to observer that auto-reloads `R/` directory to avoid confusion when using `reactlog`. ([#58](https://github.com/rstudio/reactlog/issues/58))
-
-* `getDefaultReactiveDomain()` can now be called inside a `session$onSessionEnded` callback and will return the calling `session` information. ([#2757](https://github.com/rstudio/shiny/pull/2757))
-
-* Added a `'function'` class to `reactive()` and `reactiveVal()` objects. ([#2793](https://github.com/rstudio/shiny/pull/2793))
-
-### Bug fixes
-
-* Fixed [#2606](https://github.com/rstudio/shiny/issues/2606): `debounce()` would not work properly if the code in the reactive expression threw an error on the first run. ([#2652](https://github.com/rstudio/shiny/pull/2652))
-
-* Fixed [#2653](https://github.com/rstudio/shiny/issues/2653): The `dataTableOutput()` could have incorrect output if certain characters were in the column names. ([#2658](https://github.com/rstudio/shiny/pull/2658))
-
-### Documentation Updates
-
-
-shiny 1.4.0.2
-===========
-
-Minor patch release: fixed some timing-dependent tests failed intermittently on CRAN build machines.
-
-
-shiny 1.4.0.1
-===========
-
-Minor patch release to account for changes to the grid package that will be upcoming in the R 4.0 release ([#2776](https://github.com/rstudio/shiny/pull/2776)).

-## Full changelog
-
-### Breaking changes
-
-* Resolved [#2554](https://github.com/rstudio/shiny/issues/2554): Upgraded jQuery from v.1.12.4 to v3.4.1 and bootstrap from v3.3.7 to v3.4.1. ([#2557](https://github.com/rstudio/shiny/pull/2557)). Since the jQuery upgrade may introduce breaking changes to user code, there is an option to switch back to the old version by setting `options(shiny.jquery.version = 1)`. If you've hard-coded `shared/jquery[.min].js` in the HTML of your Shiny app, in order to downgrade, you'll have to change that filepath to `shared/legacy/jquery[.min].js`.
-
-### Improvements
+## Changes
 
 * Resolved [#1433](https://github.com/rstudio/shiny/issues/1433): `plotOutput()`'s coordmap info now includes discrete axis limits for **ggplot2** plots. As a result, any **shinytest** tests that contain **ggplot2** plots with discrete axes (that were recorded before this change) will now report differences that can safely be updated. This new coordmap info was added to correctly infer what data points are within an input brush and/or near input click/hover in scenarios where a non-trivial discrete axis scale is involved (e.g., whenever `scale_[x/y]_discrete(limits = ...)` and/or free scales across multiple discrete axes are used). ([#2410](https://github.com/rstudio/shiny/pull/2410))
 
-* Resolved [#2402](https://github.com/rstudio/shiny/issues/2402): An informative warning is now thrown for mis-specified (date) strings in `dateInput()`, `updateDateInput()`, `dateRangeInput()`, and `updateDateRangeInput()`. ([#2403](https://github.com/rstudio/shiny/pull/2403))
+### Improvements
 
-* If the `shiny.autoload.r` option is set to `TRUE`, all files ending in `.r` or `.R` contained in a directory named `R/` adjacent to your application are sourced when your app is started. This will become the default Shiny behavior in a future release ([#2547](https://github.com/rstudio/shiny/pull/2547))
+* Resolved [#2402](https://github.com/rstudio/shiny/issues/2402): An informative warning is now thrown for mis-specified (date) strings in `dateInput()`, `updateDateInput()`, `dateRangeInput()`, and `updateDateRangeInput()`. ([#2403](https://github.com/rstudio/shiny/pull/2403))
 
 * Resolved [#2442](https://github.com/rstudio/shiny/issues/2442): The `shiny:inputchanged` JavaScript event now triggers on the related input element instead of `document`. Existing event listeners bound to `document` will still detect the event due to event bubbling. ([#2446](https://github.com/rstudio/shiny/pull/2446))
 
 * Fixed [#1393](https://github.com/rstudio/shiny/issues/1393), [#2223](https://github.com/rstudio/shiny/issues/2223): For plots with any interactions enabled, the image is no longer draggable. ([#2460](https://github.com/rstudio/shiny/pull/2460))
 
-* Resolved [#2469](https://github.com/rstudio/shiny/issues/2469): `renderText` now takes a `sep` argument that is passed to `cat`. ([#2497](https://github.com/rstudio/shiny/pull/2497))
-
-* Added `resourcePaths()` and `removeResourcePaths()` functions. ([#2459](https://github.com/rstudio/shiny/pull/2459))
-
-* Resolved [#2433](https://github.com/rstudio/shiny/issues/2433): An informative warning is now thrown if subdirectories of the app's `www/` directory are masked by other resource prefixes and/or the same resource prefix is mapped to different local file paths. ([#2434](https://github.com/rstudio/shiny/pull/2434))
-
-* Resolved [#2478](https://github.com/rstudio/shiny/issues/2478): `cmd + shift + f3` and `ctrl + shift + f3` can now be used to add a reactlog mark. If reactlog keybindings are used and the reactlog is not enabled, an error page is displayed showing how to enable reactlog recordings. ([#2560](https://github.com/rstudio/shiny/pull/2560))
-
-### Bug fixes
-
 * Partially resolved [#2423](https://github.com/rstudio/shiny/issues/2423): Reactivity in Shiny leaked some memory, because R can leak memory whenever a new symbols is interned, which happens whenever a new name/key is used in an environment. R now uses the fastmap package, which avoids this problem. ([#2429](https://github.com/rstudio/shiny/pull/2429))
 
-* Fixed [#2267](https://github.com/rstudio/shiny/issues/2267): Fixed a memory leak with `invalidateLater`. ([#2555](https://github.com/rstudio/shiny/pull/2555))
+* Resolved [#2469](https://github.com/rstudio/shiny/issues/2469): `renderText` now takes a `sep` argument that is passed to `cat`. ([#2497](https://github.com/rstudio/shiny/pull/2497))
 
-* Fixed [#1548](https://github.com/rstudio/shiny/issues/1548): The `reactivePoll` function leaked an observer; that is the observer would continue to exist even if the `reactivePoll` object was no longer accessible. [#2522](https://github.com/rstudio/shiny/pull/2522)
+* Resolved [#2515](https://github.com/rstudio/shiny/issues/2515): `selectInput()` now deals appropriately with named factors. ([#2524](https://github.com/rstudio/shiny/pull/2524))
 
-* Fixed [#2116](https://github.com/rstudio/shiny/issues/2116): Fixed an issue where dynamic tabs could not be added when on a hosted platform. ([#2545](https://github.com/rstudio/shiny/pull/2545))
-
-* Resolved [#2515](https://github.com/rstudio/shiny/issues/2515): `selectInput()` and `selectizeInput()` now deal appropriately with named factors. Note that `updateSelectInput()` and `updateSelectizeInput()` **do not** yet handle factors; their behavior is unchanged. ([#2524](https://github.com/rstudio/shiny/pull/2524), [#2540](https://github.com/rstudio/shiny/pull/2540), [#2625](https://github.com/rstudio/shiny/pull/2625))
-
-* Resolved [#2471](https://github.com/rstudio/shiny/issues/2471): Large file uploads to a Windows computer were slow. ([#2579](https://github.com/rstudio/shiny/pull/2579))
+### Bug fixes
 
 * Fixed [#2387](https://github.com/rstudio/shiny/issues/2387): Updating a `sliderInput()`'s type from numeric to date no longer changes the rate policy from debounced to immediate. More generally, updating an input binding with a new type should (no longer) incorrectly alter the input rate policy. ([#2404](https://github.com/rstudio/shiny/pull/2404))

 * Fixed [#2233](https://github.com/rstudio/shiny/issues/2233): `verbatimTextOutput()` produced wrapped text on Safari, but the text should not be wrapped. ([#2353](https://github.com/rstudio/shiny/pull/2353))
 
-* Fixed [#2335](https://github.com/rstudio/shiny/issues/2335): When `dateInput()`'s `value` was unspecified, and `max` and/or `min` was set to `Sys.Date()`, the value was not being set properly. ([#2526](https://github.com/rstudio/shiny/pull/2526))
-
-* Fixed [#2591](https://github.com/rstudio/shiny/issues/2591): Providing malformed date-strings to `min` or `max` no longer results in JS errors for `dateInput()` and `dateRangeInput()`. ([#2592](https://github.com/rstudio/shiny/pull/2592))
-
 * Fixed [rstudio/reactlog#36](https://github.com/rstudio/reactlog/issues/36): Changes to reactive values not displaying accurately in reactlog. ([#2424](https://github.com/rstudio/shiny/pull/2424))
 
-* Fixed [#2598](https://github.com/rstudio/shiny/issues/2598): Showcase files don't appear with a wide window. ([#2582](https://github.com/rstudio/shiny/pull/2582))
-
 * Fixed [#2329](https://github.com/rstudio/shiny/issues/2329), [#1817](https://github.com/rstudio/shiny/issues/1817): These bugs were reported as fixed in Shiny 1.3.0 but were not actually fixed because some JavaScript changes were accidentally not included in the release. The fix resolves issues that occur when `withProgressBar()` or bookmarking are combined with the [networkD3](https://christophergandrud.github.io/networkD3/) package's Sankey plot.

+#' Remove a UI object from the app.
+#'
+#' This function allows you to remove any part of your UI. Once `removeUI`
+#' is executed on some element, it is gone forever.
+#'
+#' While it may be a particularly useful pattern to pair this with
+#' [insertUI()] (to remove some UI you had previously inserted),
+#' there is no restriction on what you can use `removeUI` on. Any
+#' element that can be selected through a jQuery selector can be removed
+#' through this function.
+#'
+#' @param selector A string that is accepted by jQuery's selector (i.e. the
+#' string `s` to be placed in a `$(s)` jQuery call). This selector
+#' will determine the element(s) to be removed. If you want to remove a
+#' Shiny input or output, note that many of these are wrapped in `div`s,
+#' so you may need to use a somewhat complex selector --- see the Examples below.
+#' (Alternatively, you could also wrap the inputs/outputs that you want to be
+#' able to remove easily in a `div` with an id.)
+#'
+#' @param multiple In case your selector matches more than one element,
+#' `multiple` determines whether Shiny should remove all the matched
+#' elements or just the first matched element (default).
+#'
+#' @param immediate Whether the element(s) should be immediately removed from
+#' the app when you call `removeUI`, or whether Shiny should wait until
+#' all outputs have been updated and all observers have been run (default).
+#'
+#' @param session The shiny session within which to call `removeUI`.
