+## 0.30.0 - 2024-12-16 - Modals and better layer support
+
+### ✨ Highlights
+* Add `Modal`, a popup that blocks input to the rest of the application ([#5358](https://github.com/emilk/egui/pull/5358) by [@lucasmerlin](https://github.com/lucasmerlin))
+* Improved support for transform layers ([#5465](https://github.com/emilk/egui/pull/5465), [#5468](https://github.com/emilk/egui/pull/5468), [#5429](https://github.com/emilk/egui/pull/5429))
+
+#### `egui_kittest`
+This release welcomes a new crate to the family: [egui_kittest](https://github.com/emilk/egui/tree/master/crates/egui_kittest).
+`egui_kittest` is a testing framework for egui, allowing you to test both automation (simulated clicks and other events),
+and also do screenshot testing (useful for regression tests).
+`egui_kittest` is built using [`kittest`](https://github.com/rerun-io/kittest), which is a general GUI testing framework that aims to work with any Rust GUI (not just egui!).
+`kittest` uses the accessibility library [`AccessKit`](https://github.com/AccessKit/accesskit/) for automatation and to query the widget tree.
+
+`kittest` and `egui_kittest` are written by [@lucasmerlin](https://github.com/lucasmerlin).
+
+Here's a quick example of how to use `egui_kittest` to test a checkbox:
+
+```rust
+use egui::accesskit::Toggled;
+use egui_kittest::{Harness, kittest::Queryable};
+
+fn main() {
+    let mut checked = false;
+    let app = |ui: &mut egui::Ui| {
+        ui.checkbox(&mut checked, "Check me!");
+    };
+
+    let mut harness = egui_kittest::Harness::new_ui(app);
+
+    let checkbox = harness.get_by_label("Check me!");
+    assert_eq!(checkbox.toggled(), Some(Toggled::False));
+    checkbox.click();
+
+    harness.run();
+
+    let checkbox = harness.get_by_label("Check me!");
+    assert_eq!(checkbox.toggled(), Some(Toggled::True));
+
+    // You can even render the ui and do image snapshot tests
+    #[cfg(all(feature = "wgpu", feature = "snapshot"))]
+    harness.wgpu_snapshot("readme_example");
+}
+```
