-# shiny (development version)
+# shiny 1.9.1
 
 ## Bug fixes
 
+* Fixed a bug introduced in v1.9.0 where the boundaries of hover/click/brush regions on plots were being incorrectly scaled when browser zoom was used. (#4111)
+
+# shiny 1.9.0
+
+## New busy indication feature
+
+Add the new `useBusyIndicators()` function to any UI definition to:
+  1. Add a spinner overlay on calculating/recalculating outputs.
+  2. Show a page-level pulsing banner when Shiny is busy calculating something (e.g., a download, side-effect, etc), but no calculating/recalculating outputs are visible.
+
+In a future version of Shiny, busy indication will be enabled by default, so we encourage you to try it out now, provide feedback, and report any issues.
+
+In addition, various properties of the spinners and pulse can be customized with `busyIndicatorOptions()`. For more details, see `?busyIndicatorOptions`. (#4040, #4104)
+
+## New features and improvements
+
+* The client-side TypeScript code for Shiny has been refactored so that the `Shiny` object is now an instance of class `ShinyClass`. (#4063)
+
+* In TypeScript, the `Shiny` object has a new property `initializedPromise`, which is a Promise-like object that can be `await`ed or chained with `.then()`. This Promise-like object corresponds to the `shiny:sessioninitialized` JavaScript event, but is easier to use because it can be used both before and after the events have occurred. (#4063)
+
+* Output bindings now include the `.recalculating` CSS class when they are first bound, up until the first render. This makes it possible/easier to show progress indication when the output is calculating for the first time. (#4039)
+
+* A new `shiny.client_devmode` option controls client-side devmode features, in particular the client-side error console introduced in shiny 1.8.1, independently of the R-side features of `shiny::devmode()`. This usage is primarily intended for automatic use in Shinylive. (#4073)
+
+* Added function `reactlogAddMark()` to programmatically add _mark_ed locations in the reactlog log without the requirement of keyboard bindings during an idle reactive moment. (#4103)
+
+## Bug fixes
+
+* `downloadButton()` and `downloadLink()` are now disabled up until they are fully initialized. This prevents the user from clicking the button/link before the download is ready. (#4041)
+
+* Output bindings that are removed, invalidated, then inserted again (while invalidated) now correctly include the `.recalculating` CSS class. (#4039)
+
 * Fixed a recent issue with `uiOutput()` and `conditionalPanel()` not properly lower opacity when recalculation (in a Bootstrap 5 context). (#4027)
 
+* Image outputs that were scaled by CSS had certain regions that were unresponsive to hover/click/brush handlers. (#3234)
+
 # shiny 1.8.1.1
 
 * In v1.8.1, shiny.js starting throwing an error when input/output bindings have duplicate IDs. This error is now only thrown when `shiny::devmode(TRUE)` is enabled, so the issue is still made discoverable through the JS error console, but avoids unnecessarily breaking apps that happen to work with duplicate IDs. (#4019)
@@ -16,7 +50,7 @@
 
 * Added a JavaScript error dialog, reporting errors that previously were only discoverable by opening the browser's devtools open. Since this dialog is mainly useful for debugging and development, it must be enabled with `shiny::devmode()`. (#3931)
 
-* `runExamples()` now uses the `{bslib}` package to generate a better looking result. It also gains a `package` argument so that other packages can leverage this same function to run Shiny app examples. For more, see `?runExamples`. (#3963, #4005)

 * Added `onUnhandledError()` to register a function that will be called when an unhandled error occurs in a Shiny app. Note that this handler doesn't stop the error or prevent the session from closing, but it can be used to log the error or to clean up session-specific resources.

+#' Customize busy indicator options
+#'
+#' @description
+#' Shiny automatically includes busy indicators, which more specifically means:
+#'   1. Calculating/recalculating outputs have a spinner overlay.
+#'   2. Outputs fade out/in when recalculating.
+#'   3. When no outputs are calculating/recalculating, but Shiny is busy
+#'     doing something else (e.g., a download, side-effect, etc), a page-level
+#'     pulsing banner is shown.
+#'
+#' This function allows you to customize the appearance of these busy indicators
+#' by including the result of this function inside the app's UI. Note that,
+#' unless `spinner_selector` (or `fade_selector`) is specified, the spinner/fade
+#' customization applies to the parent element. If the customization should
+#' instead apply to the entire page, set `spinner_selector = 'html'` and
+#' `fade_selector = 'html'`.
+#'
+#' @param ... Currently ignored.
+#' @param spinner_type The type of spinner. Pre-bundled types include:
+#'   '`r paste0(.busySpinnerTypes, collapse = "', '")`'.
+#'
+#'   A path to a local SVG file can also be provided. The SVG should adhere to
+#'   the following rules:
+#'   * The SVG itself should contain the animation.
+#'   * It should avoid absolute sizes (the spinner's containing DOM element
+#'     size is set in CSS by `spinner_size`, so it should fill that container).
+#'   * It should avoid setting absolute colors (the spinner's containing DOM element
+#'     color is set in CSS by `spinner_color`, so it should inherit that color).
+#' @param spinner_color The color of the spinner. This can be any valid CSS
+#'   color. Defaults to the app's "primary" color if Bootstrap is on the page.
+#' @param spinner_size The size of the spinner. This can be any valid CSS size.
+#' @param spinner_delay The amount of time to wait before showing the spinner.
+#'   This can be any valid CSS time and can be useful for not showing the spinner
+#'   if the computation finishes quickly.
+#' @param spinner_selector A character string containing a CSS selector for
+#'   scoping the spinner customization. The default (`NULL`) will apply the
+#'   spinner customization to the parent element of the spinner.
+#' @param fade_opacity The opacity (a number between 0 and 1) for recalculating
+#'   output. Set to 1 to "disable" the fade.
+#' @param fade_selector A character string containing a CSS selector for
+#'   scoping the spinner customization. The default (`NULL`) will apply the
+#'   spinner customization to the parent element of the spinner.
+#' @param pulse_background A CSS background definition for the pulse. The
+#'   default uses a
+#'   [linear-gradient](https://developer.mozilla.org/en-US/docs/Web/CSS/gradient/linear-gradient)
+#'   of the theme's indigo, purple, and pink colors.
+#' @param pulse_height The height of the pulsing banner. This can be any valid
+#'   CSS size.

+\item{...}{Currently ignored.}
+
+\item{spinners}{Whether to show a spinner on each calculating/recalculating
+output.}
+
+\item{pulse}{Whether to show a pulsing banner at the top of the page when the

+\item{fade}{Whether to fade recalculating outputs. A value of \code{FALSE} is
+equivalent to \code{busyIndicatorOptions(fade_opacity=1)}.}
+}
+\description{
+Busy indicators provide a visual cue to users when the server is busy
+calculating outputs or otherwise performing tasks (e.g., producing
+downloads). When enabled, a spinner is shown on each
+calculating/recalculating output, and a pulsing banner is shown at the top of
+the page when the app is otherwise busy. Busy indication is enabled by
+default for UI created with \pkg{bslib}, but must be enabled otherwise. To
+enable/disable, include the result of this function in anywhere in the app's
+UI.
+}
+\details{
+When both \code{spinners} and \code{pulse} are set to \code{TRUE}, the pulse is
+automatically disabled when spinner(s) are active. When both \code{spinners} and
+\code{pulse} are set to \code{FALSE}, no busy indication is shown (other than the
+graying out of recalculating outputs).

+ * A state machine for tracking Shiny output progress.
+ *
+ * Although there are a handful of possible states, the ultimate goal here is to
+ * be able to say whether a given output `isRecalculating()` or not (and thus,
+ * whether we should show progress indication or not).
+ *
+ * The diagram below depicts the state machine. Each node represents a possible
+ * state and each edge represents a server-->client message that moves outputs
+ * from one state to another. If a node name is all caps, then the output should
+ * be showing a busy state when visible (i.e., `binding.showProgress(true)`).
+ *
+ * A more polished SVG version of this diagram can be found here:
+ * https://github.com/rstudio/shiny/blob/main/inst/diagrams/outputProgressStateMachine.svg
