-/**
- * The inputs in this block intentionally VIOLATE the (soft) invariant that a
- * frame's children — and a group's members — are contiguous in the elements
- * array. Such states shouldn't occur in normal use, but they CAN arise from
- * bugs or broken input, because nothing re-defragments element order during
- * a reorder (`normalizeElementOrder` only runs on duplication). We keep these
- * tests so the reordering ops stay exercised against malformed order.
- *
- * HARD CONTRACT (a failure here is a real bug): a reorder must never throw,
- * duplicate, or drop elements. `assertReorderPreservesElements` checks this.
- *
- * SOFT SNAPSHOT (read before "fixing"): the exact resulting ORDER is NOT a
- * contract for invalid input — it's whatever the slice math happens to
- * produce. If a future change alters an `expected` order below, that is NOT
- * necessarily a functional regression. First confirm from the diff that the
- * hard contract still holds (nothing duplicated/lost), then update the
- * expected order to match, provided it's deemed an improvement over the
- * previous order, or it's an acceptable change given the underlying logic
- * change.

@@ -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).
