 ### New features and improvements
 
-* Closed #789: `<script>` loaded from dynamic UI are no longer loaded using synchronous `XMLHttpRequest` (via jQuery). (#3666)
+* Closed #789: Dynamic UI is now rendered asynchronously, thanks in part to the newly exported `Shiny.renderDependenciesAsync()`, `Shiny.renderHtmlAsync()`, and `Shiny.renderContentAsync()`. Importantly, this means `<script>` tags are now loaded asynchronously (the old way used `XMLHttpRequest`, which is synchronous). In addition, `Shiny` now manages a queue of async tasks (exposed via `Shiny.shinyapp.taskQueue`) so that order of execution is preserved. (#3666)
+
+* For `reactiveValues()` objects, whenever the `$names()` or `$values()` methods are called, the keys are now returned in the order that they were inserted. (#3774)
+
+* `Map` objects are now initialized at load time instead of build time. This avoids potential problems that could arise from storing `fastmap` objects into the built Shiny package. (#3775)
+
+* Allow for `shiny:::toJSON()` to respect if `digits=` has class `"AsIs"` which represents if `use_signif=` is `TRUE` or `FALSE`. This is useful for testing to keep the digits smaller. For example, setting `options(shiny.json.digits = 4)` will save 4 digits after the decimal, rather than the default of `I(16)` which will save 16 significant digits. (#3819)
 
 ### Bug fixes
 
+* Fixed #3771: Sometimes the error `ion.rangeSlider.min.js: i.stopPropagation is not a function` would appear in the JavaScript console. (#3772)
+
+* Fixed #3833: When `width` is provided to `textAreaInput()`, we now correctly set the width of the `<textarea>` element. (#3838)
+
+* Fixes #3840: `updateSliderInput()` now warns when attempting to set invalid `min`, `max`, or `value` values. Sending an invalid update message to an input no longer causes other update messages to fail. (#3843)
+
+
+# shiny 1.7.4.1

+* Closed #3849: In R-devel, a warning was raised when Shiny was loaded because `as.numeric_version()` was called with a number instead of a string. (#3850)

 ### New features and improvements
 
-* `plotOutput()`, `imageOutput()`, and `uiOutput()` gain a `fill` argument. If `TRUE` (the default for `plotOutput()`), the output container is allowed to grow/shrink to fit a fill container (created via `htmltools::bindFillRole()`) with an opinionated height. This means `plotOutput()` will grow/shrink by default [inside of `bslib::card_body_fill()`](https://rstudio.github.io/bslib/articles/cards.html#responsive-sizing), but `imageOutput()` and `uiOutput()` will have to opt-in to similar behavior with `fill = TRUE`.

 1. Better theming (and Bootstrap 4) support:
   * The `theme` argument of `fluidPage()`, `navbarPage()`, and `bootstrapPage()` all now understand `bslib::bs_theme()` objects, which can be used to opt-into Bootstrap 4, use any Bootswatch theme, and/or implement custom themes without writing any CSS.
-  * The `session` object now includes `$setCurrentTheme()` and `$getCurrentTheme()` methods to dynamically update (or obtain) the page's `theme` after initial load, which is useful for things such as [adding a dark mode switch to an app](https://rstudio.github.io/bslib/articles/bslib.html#dynamic) or some other "real-time" theming tool like `bslib::bs_themer()`.
