-### New features and improvements
+* `fileInput()` no longer has unwanted round corners applied to the `buttonLabel`. (#3879)
 
-* Closed #789: `<script>` loaded from dynamic UI are no longer loaded using synchronous `XMLHttpRequest` (via jQuery). (#3666)
+# shiny 1.7.5
+
+## Possibly breaking changes
 
 * For `reactiveValues()` objects, whenever the `$names()` or `$values()` methods are called, the keys are now returned in the order that they were inserted. (#3774)
 
+* The value provided to `options(shiny.json.digits)` is now interpreted as number of _digits after the decimal_ instead of _significant digits_. To treat the value as significant digits, wrap it in `I()` (e.g., `options(shiny.json.digits = I(4))`). This new default behavior not only helps with reducing digits in testing snapshots, but is also more consistent with `{jsonlite}`'s default behavior. (#3819)
+
+## New features and improvements
+
+* 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)
+
+* 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)
+
+* `sliderInput()` now has a larger target area for clicking or tapping on the slider handle or range. (#3859)
+
+* Closed #2956: Component authors can now prevent Shiny from creating an input binding on specific elements by adding the `data-shiny-no-bind-input` attribute to the element. The attribute may have any or no value; its presence will prevent binding. This feature is primarily useful for input component authors who want to use standard HTML input elements without causing Shiny to create an input binding for them. Additionally, Shiny now adds custom classes to its inputs. For example, `checkboxInput()` now has a `shiny-input-checkbox` class. These custom classes may be utilized in future updates to Shiny's input binding logic. (#3861)
+
 * `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)
 
-### Bug fixes
+## 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)
+
+
+# shiny 1.7.4.1

@@ -165,7 +189,7 @@ This release focuses on improvements in three main areas:
 
 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()`.

 * An attractive default look based on [Bootstrap](https://getbootstrap.com/) which can also be easily customized with the [bslib](https://github.com/rstudio/bslib) package or avoided entirely with more direct R bindings to HTML/CSS/JavaScript.
 * Seamless integration with [R Markdown](https://shiny.rstudio.com/articles/interactive-docs.html), making it easy to embed numerous applications natively within a larger dynamic document.

 For help with learning fundamental Shiny programming concepts, check out the [Mastering Shiny](https://mastering-shiny.org/) book and the [Shiny Tutorial](https://shiny.rstudio.com/tutorial/). The former is currently more up-to-date with modern Shiny features, whereas the latter takes a deeper, more visual, dive into fundamental concepts.
