+# 19.3.2: Clean release artifacts
+
+Builds now clear previous output before compilation. This prevents stale,
+unused files from entering the package after a compiler configuration change.
+
+# 19.3.1: Batched Transformer updates
+
+With Konva 10.9+, react-konva batches automatic Transformer updates across each
+canvas commit. Updating many selected nodes triggers one Transformer refresh
+after the mutations. Layout effects see the final anchor positions.
+
+This works automatically. Upgrade Konva to enable it:
+
+```sh
+npm install react-konva@19.3.1 konva@^10.9.0
+```
+
+Older supported Konva versions keep their existing behavior and do not require
+the new batching API. React and React DOM still require matching 19.3+ versions
+within React 19.
+
+Updates the context bridge and renderer types, with the same React 19.3.0 minimum.
+
+Attribute-change listeners run during mutation. They can read the changed
+attributes and Transformer bounds synchronously. To read final anchor positions,
+use a layout effect or call `transformer.update()` explicitly in the listener.
+
+## Validation
+
+The suite covers 203 correctness tests per build and 41 performance checks,
+including resizing 600 selected shapes. Regression tests cover individual
+selections, selected Groups, layout reads, and a missing batching API.
+Package checks cover server rendering, both module formats, consumer types,
+package exports, and React DevTools.
+
+# 19.3.0: React 19.3 support
+
+## Upgrade requirements
+
+Upgrade React and React DOM to matching 19.3 versions before you install this release.
+The minimum React and React DOM version is now 19.3.0.
+
+```sh
+npm install react@19.3.0 react-dom@19.3.0 react-konva@19.3.0
+```
+
+For React 19.2 projects, pin `react-konva` to `~19.2.7`.
+The range `^19.2.7` also allows 19.3.0, which requires the React upgrade.
+For React 18 projects, use the React Konva 18 release line.
+
+## Fixes and improvements
+
+- Fixes the `useActionState` crash inside `Stage` with React 19.3. This resolves [#859](https://github.com/konvajs/react-konva/issues/859) through [#860](https://github.com/konvajs/react-konva/pull/860).
+- Updates the bundled `react-reconciler` to 0.34.0 and `scheduler` to 0.28.0 for React 19.3.
+- Canvas roots inherit React StrictMode checks from the DOM tree.
+- Activity and Suspense preserve canvas state and node identity through hiding and reveal. Effects and refs disconnect and reconnect as each boundary requires.
+- Stage removal discards pending child updates and runs effect cleanup, including for hidden Stages.
+- Canvas components read the surrounding DOM form status through `useFormStatus`, including the submitted data and action.
+- `useId` values remain stable on updates and distinct across DOM and Stage roots.
+- Both package formats register with React DevTools. Development builds support hook state changes.
+
+## Renderer boundaries
+
+Error boundaries inside `Stage` handle canvas errors and display Konva fallbacks.
+DOM error boundaries around `Stage` do not catch errors from canvas children.
+Uncaught canvas errors appear in the console with the original error and component stack, including errors during cleanup.
+
+Canvas Suspense boundaries display Konva fallbacks.
+Canvas suspension does not activate a surrounding DOM Suspense boundary.
+A promise read before Stage renders can activate that DOM fallback.
+
+A DOM `ViewTransition` can animate the Stage container.
+A `ViewTransition` inside Stage with Konva nodes or a ref throws a clear error.
+Fragment children remain supported, but Fragment refs stay `null` and provide no DOM methods.
+
+The [React compatibility matrix](docs/react-compatibility.md) lists the supported hooks, features, fallbacks, and remaining limits.
+Native input synchronization and the fallback for older Konva versions continue from [19.2.7](https://github.com/konvajs/react-konva/blob/d9c73c21a5c164d5551ca62c15d5aa150a420053/RELEASE_NOTES.md).
+
+## Validation
+
+CI passes with Chromium, Firefox, and WebKit in development and production.
+The minimum React and React DOM 19.3.0 job also passes.
+The suite covers 196 correctness tests per build and 38 performance checks.
+Package checks cover both module formats, server rendering, package exports, consumer types, and the DevTools protocol.
