 * `PaintCallback` shapes now require the whole callback to be put in an `Arc<dyn Any>` with the value being a backend-specific callback type ([#1684](https://github.com/emilk/egui/pull/1684)).
 * Replaced `needs_repaint` in `FullOutput` with `repaint_after`. Used to force repaint after the set duration in reactive mode ([#1694](https://github.com/emilk/egui/pull/1694)).
 * `Layout::left_to_right` and `Layout::right_to_left` now takes the vertical align as an argument. Previous default was `Align::Center`.
+* Improved ergonomics of adding plot items. All plot items that take a series of 2D coordinates can now be created directly from `Vec<[f64; 2]>`. The `Value` and `Values` types were removed in favor of `PlotPoint` and `PlotPoints` respectively.
 
 ### Fixed 🐛
 * Fixed `Response::changed` for `ui.toggle_value` ([#1573](https://github.com/emilk/egui/pull/1573)).
