 ## Full changelog
 
 ### Breaking changes
 
-### Minor new features and improvements
+### 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)
+
+* 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)
+
+* 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)
+
+* Slider inputs created with `sliderInput()` now have a larger target area for clicking or tapping on the slider line or the slider bar. (#3859)
+
+
+### 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
+
+## Full changelog
+
+* 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)
+
+
+# shiny 1.7.4
+
+## Full changelog
+
+### Breaking changes
+
+* Closed #3719: Output container sizes, which are available via [`session$clientData` and `getCurrentOutputInfo()`](https://shiny.rstudio.com/articles/client-data.html), no longer round to the nearest pixel (i.e., they are now more exact, possibly fractional values). (#3720)
+
+* Closed #3704, #3735, and #3740: `renderPlot()` no longer generates an error (or segfault) when it executes before the output is visible. Instead, it'll now use the graphics device's default size for it's initial size. Relatedly, `plotPNG()` now ignores `NULL` values for `width`/`height` (and uses the device's default `width`/`height` instead). (#3739)
+
+### 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`. (#3715)
+
+* Closed #3687: Updated jQuery-UI to v1.13.2. (#3697)
+
+* Internal: Added clearer and strict TypeScript type definitions (#3644)
+
+
+# shiny 1.7.3
+
+### Bug fixes
+
+* Shiny 1.7.0 changed the `icon(lib="fontawesome")` implementation from a bundled copy of fontawesome, to the {fontawesome} package. This led to issue #3688, where icons that were previously working, were now breaking. That's because {fontawesome} 0.3.0 and earlier did not have support for icon names used in Font Awesome 5 and earlier, only the newest icon names used in Font Awesome 6. Now, {fontawesome} 0.4.0 has restored support for those older icon names, and Shiny 1.7.2.1 has updated its {fontawesome} requirement to >=0.4.0.
+
+
+# shiny 1.7.2
+
+## Full changelog
+
+### Breaking changes
+
+* Closed #3626: `renderPlot()` (and `plotPNG()`) now uses `ragg::agg_png()` by default when the [`{ragg}` package](https://github.com/r-lib/ragg) is installed. To restore the previous behavior, set `options(shiny.useragg = FALSE)`. (#3654)
+
+### New features and improvements
+
+* Closed #1545: `insertUI()` now executes `<script>` tags. (#3630)
+
+* `fileInput()` can set the `capture` attribute to facilitates user access to a device's media capture mechanism, such as a camera, or microphone, from within a file upload control ([W3C HTML Media Capture](https://www.w3.org/TR/html-media-capture/)). (Thanks to khaled-alshamaa, #3481)
+
+* Closed tidyverse/dplyr#5552: Compatibility of dplyr 1.0 (and rlang chained errors in general) with `req()`, `validate()`, and friends.
+
+* Closed tidyverse/dplyr#6154: Values from an `actionButton()` had S3 classes in the incorrect order.
+
+* Closed #3346: Default for `ref` input in `runGithub()` changed from `"master"` to `"HEAD"`. (#3564)
+
+* Closed #3619: In R 4.2, `splitLayout()` no longer raises warnings about incorrect length in an `if` statement. (Thanks to @dmenne, #3625)
+
+### Bug fixes
+
+* Closed #3250:`{rlang}`/`{tidyeval}` conditions (i.e., warnings and errors) are no longer filtered from stack traces. (#3602)
+
+* Closed #3581: Errors in throttled/debounced reactive expressions no longer cause the session to exit. (#3624)
+
+* Closed #3657: `throttle.ts` and the `Throttler` typescript objects it provides now function as intended. (Thanks gto @dvg-p4, #3659)
+
+* The auto-reload feature (`options(shiny.autoreload=TRUE)`) was not being activated by `devmode(TRUE)`, despite a console message asserting that it was. (#3620)
+
+* Closed #2297: If an error occurred in parsing a value in a bookmark query string, an error would be thrown and nothing would be restored. Now a message is displayed and that value is ignored. (Thanks to @daattali, #3385)
+
+* Restored the previous behavior of automatically guessing the `Content-Type` header for `downloadHandler` functions when no explicit `contentType` argument is supplied. (#3393)
+
+* Previously, updating an input value without a corresponding Input binding element did not trigger a JavaScript `shiny:inputchanged` event. Now, if no Input binding element is found, the `shiny:inputchanged` event is triggered on `window.document`. (#3584)
+
+* Closed #2955: Input and output bindings previously attempted to use `el['data-input-id']`, but that never worked. They now use `el.getAttribute('data-input-id')` instead. (#3538)
+
+### Minor improvements
+
+* When taking a test snapshot, the sort order of the json keys of the `input`, `output`, and `export` fields is currently sorted using the locale of the machine. This can lead to inconsistent test snapshot results. To opt-in to a consistent ordering of snapshot fields with `{shinytest}`, please set the global option `options(shiny.snapshotsortc = TRUE)`. `{shinytest2}` users do not need to set this value. (#3515)
+
+* Closed rstudio/shinytest2#222: When restoring a context (i.e., bookmarking) from a URL, Shiny now better handles a trailing `=` after `_inputs_` and `_values_`. (#3648)
 
 * Shiny's internal HTML dependencies are now mounted dynamically instead of statically. (#3537)
 
 * HTML dependencies that are sent to dynamic UI now have better type checking, and no longer require a `dep.src.href` field. (#3537)
 
-* Default for `ref` input in `runGithub()` changed from `"master"` to `"HEAD"`. (#3346)

Shiny gives you a fair amount of control in where the cache is stored and how cached plots are invalidated, so be sure to read [this article](https://shiny.rstudio.com/articles/plot-caching.html) to get the most out of this feature.

 This is a significant release for Shiny, with a major new feature that was nearly a year in the making: support for asynchronous operations! Until now, R's single-threaded nature meant that performing long-running calculations or tasks from Shiny would bring your app to a halt for other users of that process. This release of Shiny deeply integrates the [promises](https://rstudio.github.io/promises/) package to allow you to execute some tasks asynchronously, including as part of reactive expressions and outputs. See the [promises](https://rstudio.github.io/promises/) documentation to learn more.
