 * `textAreaInput()` gains a `autoresize` option, which automatically resizes the text area to fit its content. (#4210)
 
+## Changes
+
+* Shiny no longer suspends input changes when _any_ `<input type="submit">` or `<button type="submit">` is on the page. Instead, it now only suspends when a `submitButton()` is present. If you have reason for creating a submit button from custom HTML, add a CSS class of `shiny-submit-button` to the button. (#4209)
+
 ## Improvements
 
 * When auto-reload is enabled, Shiny now reloads the entire app when support files, like Shiny modules, additional script files, or web assets, change. To enable auto-reload, call `devmode(TRUE)` to enable Shiny's developer mode, or set `options(shiny.autoreload = TRUE)` to specifically enable auto-reload. You can choose which files are watched for changes with the `shiny.autoreload.pattern` option. (#4184)
