@@ -17,13 +17,6 @@ Please add the latest change on the top under the correct section.
 
 ### Breaking changes
 
-- Theme changes initiated by the default UI are now delegated to `<Excalidraw onThemeChange={(theme) => ...} />` when supplied. If `onThemeChange` is not supplied, light/dark theme toggling still falls back to updating the internal editor state.
-
-  - `MainMenu.DefaultItems.ToggleTheme` no longer accepts the item-level `onSelect` callback. Host apps that need to control light/dark/system theme should pass `onThemeChange` to `<Excalidraw />` instead.
-  - `MainMenu.DefaultItems.ToggleTheme` with system theme support now uses `allowSystemTheme` together with `theme={Theme | "system"}` only to render the selected value. For the regular light/dark item, pass `allowSystemTheme={false}`.
-  - `CommandPalette.defaultItems.toggleTheme` was removed. The default theme command is now rendered by the command palette itself when `UIOptions.canvasActions.toggleTheme` enables the action (see below).
-  - `UIOptions.canvasActions.toggleTheme` still controls default theme UI availability. When it is `null`, it defaults to `true` if `props.theme` is omitted or `props.onThemeChange` is supplied, and otherwise defaults to disabled.
-
 - Renamed the `excalidrawAPI` prop to `onExcalidrawAPI`.
   - `onExcalidrawAPI` is now called on mount (instead of during constructor), and later on unmount (with `null` value). The API may be removed altogether in the future (you can use `onMount` & `onUmount` to manage the `ExcalidrawAPI` object (e.g. to cache it to a global state), already).

-# Laser Pointer
-
-## Usage
-
-    import { LaserPointer } from '@excalidraw/laser-pointer'
-
-    const stroke = new LaserPointer(options)
-
-    stroke.addPoint([100, 200, 1])
-    stroke.close()
-
-    const outline = stroke.getStrokeOutline()
-
-## Options
-
-| Property | Type | Default | Description |
-| --- | --- | --- | --- |
-| `size` | `number` | `2` | Radius of the stroke. |
-| `streamline` | `number` | `0.42` | Interpolate input points to reduce jitter. |
-| `simplify` | `number` | `0.1` | Reduce stroke size by sacrificing precision. |
-| `simplifyPhase` | `"input" \| "output" \| "tail" ` | `"output"` | Decides when the simplification algorithm should be applied. |
-| `sizeMapping` | `(details: SizeMappingDetails) => number` | `() => 1` | Maps each point to a value between `0.0` and `1.0`. |
-| `keepHead` | `boolean` | `false` | Whether size mapping should influence the head of the stroke. |
