 ### Added ⭐
 * `Event::Key` now has a `repeat` field that is set to `true` if the event was the result of a key-repeat ([#2435](https://github.com/emilk/egui/pull/2435)).
 * Add `Slider::drag_value_speed`, which lets you ask for finer precision when dragging the slider value rather than the actual slider.
+* Add `Memory::any_popup_open`, which returns true if any popup is currently open ([#2464](https://github.com/emilk/egui/pull/2464)).
 
 ### Fixed 🐛
 * Expose `TextEdit`'s multiline flag to AccessKit ([#2448](https://github.com/emilk/egui/pull/2448)).
