 * Added `Contex::request_repaint_after` ([#1694](https://github.com/emilk/egui/pull/1694)).
 * `ctrl-h` now acts like backspace in `TextEdit` ([#1812](https://github.com/emilk/egui/pull/1812)).
+* Added `custom_formatter` method for `Slider` and `DragValue` ([#1851](https://github.com/emilk/egui/issues/1851)).

 * `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.
