+## 0.31.0 - 2025-02-04 - Scene container, improved rendering quality
+
+### Highlights ✨
+
+#### Scene container
+This release adds the `Scene` container to egui. It is a pannable, zoomable canvas that can contain `Widget`s and child `Ui`s.
+This will make it easier to e.g. implement a graph editor.
+
+![scene](https://github.com/user-attachments/assets/7dc5e395-a3cb-4bf3-83a3-51a76a48c409)
+
+#### Clearer, pixel perfect rendering
+The tessellator has been updated for improved rendering quality and better performance. It will produce fewer vertices
+and shapes will have less overdraw. We've also defined what `CornerRadius` (previously `Rounding`) means.
+
+We've also added a tessellator test to the [demo app](https://www.egui.rs/), where you can play around with different
+values to see what's produced:
+
+
+https://github.com/user-attachments/assets/adf55e3b-fb48-4df0-aaa2-150ee3163684
+
+
+Check the [PR](https://github.com/emilk/egui/pull/5669) for more details.
+
+#### `CornerRadius`, `Margin`, `Shadow` size reduction
+In order to pave the path for more complex and customizable styling solutions, we've reduced the size of
+`CornerRadius`, `Margin` and `Shadow` values to `i8` and `u8`.
+
+
+
+### Migration guide
+- Add a `StrokeKind` to all your `Painter::rect` calls [#5648](https://github.com/emilk/egui/pull/5648)
+- `StrokeKind::default` was removed, since the 'normal' value depends on the context [#5658](https://github.com/emilk/egui/pull/5658)
+  - You probably want to use `StrokeKind::Inside` when drawing rectangles
+  - You probably want to use `StrokeKind::Middle` when drawing open paths
+- Rename `Rounding` to `CornerRadius` [#5673](https://github.com/emilk/egui/pull/5673)
+- `CornerRadius`, `Margin` and `Shadow` have been updated to use `i8` and `u8` [#5563](https://github.com/emilk/egui/pull/5563), [#5567](https://github.com/emilk/egui/pull/5567), [#5568](https://github.com/emilk/egui/pull/5568)
+  - Remove the .0 from your values
+  - Cast dynamic values with `as i8` / `as u8` or `as _` if you want Rust to infer the type
+    - Rust will do a 'saturating' cast, so if your `f32` value is bigger than `127` it will be clamped to `127`
+- `RectShape` parameters changed [#5565](https://github.com/emilk/egui/pull/5565)
+  - Prefer to use the builder methods to create it instead of initializing it directly
+- `Frame` now takes the `Stroke` width into account for its sizing, so check all views of your app to make sure they still look right.
+  Read the [PR](https://github.com/emilk/egui/pull/5575) for more info.
