+## 0.35.0 - 2026-06-25 - Inspection, egui_mcp, classes and improved IME
+
+### Highlights 
+- New egui_mcp crate based on eguis new inspection protocol
+- Set classes on your `Ui`s to modify widget behavior based on surrounding context
+- Improved IME
+
+### Egui inspection and egui_mcp
+This release includes a new inspection protocol for egui. It allows reading the accesskit tree of a running app, as well
+as sending events to control it. It's implemented via a new `InspectionPlugin` in the `egui_inspection` crate. 
+Eframe includes a new `inspection` feature. When enabled, you can enable inspection by launching the app with 
+`EGUI_INSPECTION=1`. This will cause the app to listen on port 5719. 
+
+The first inspection protocol consumer is [egui_mcp](https://github.com/rerun-io/kittest_inspector/tree/main/crates/egui_mcp). 
+It's a [mcp](https://modelcontextprotocol.io/docs/getting-started/intro) server that allows your agent to see and use
+egui apps. It can be used to have the agent use the app, reproduce bugs and verify its changes. 
+Install it via `cargo install --git https://github.com/rerun-io/kittest_inspector egui_mcp` and then add it to your
+agent via `claude mcp add egui egui-mcp`.
+
+There is also a plan of adding a general inspection gui using the same protocol, that can e.g. be used to step through 
+kittest tests frame by frame. 
+
+Here is claude using the mcp to try some of the egui demos (sped up by a lot, claude is slow):
+https://github.com/user-attachments/assets/c3dd0456-acfc-428c-8efe-f4a244c9e3ba
+
+* Add `egui_inspection` protocol and plugin [#8234](https://github.com/emilk/egui/pull/8234) by [@lucasmerlin](https://github.com/lucasmerlin)
+
+### Classes
+
+As part of [css like styling](https://github.com/emilk/egui/issues/3284), we've added classes to egui. You can already
+use them to e.g. modify widget behavior or styling based on surrounding context. 
+Add classes to the container:
+```rs 
+ui.scope_builder(UiBuilder::new().with_class("my_container"), |ui| {
+    ...
+});       
+```
+
+In your widget, check if we're in `my_container`, to e.g. change sizes or colors:
+```rs
+  let in_container = ui.stack().iter().any(|s| s.classes.has("my_container")); 
+```
+
+Today this only works for custom widgets and ui code, but the next step will be a styling system that allows you to modify built
+in widget styling based on these classes. 
+
+* Add `Classes` to `UiBuilder` and some Widgets [#7843](https://github.com/emilk/egui/pull/7843) by [@AdrienZianne](https://github.com/AdrienZianne)
+
+### Better IME composition
+
+IME visuals received an overhaul, they are now indicated by an underline and properly show the cursor during composition:
