+shiny 1.7.2.9000
+================
+
+## Full changelog
+
+### Breaking changes
+
+### New features and improvements
+
+* Internal: Added clearer and strict TypeScript type definitions (#3644)
+
+### Bug fixes
+
+* Closed #3687: Updated jQuery-UI to v1.13.2. (#3697)
+
+
+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)
