+## v0.9.1
+
+February 2026
+
+### Fixed: Install failure due to private dependency
+
+`@json-render/react`, `@json-render/react-pdf`, and `@json-render/react-native` v0.9.0 failed to install because `@internal/react-state` (a private workspace package) was published as a dependency. The internal package is now bundled into each renderer at build time, so it no longer needs to be resolved from npm.

+[XState Store](https://stately.ai/docs/xstate-store) adapter for json-render's `StateStore` interface. Wire an `@xstate/store` atom as the state backend for json-render.
+
+## Installation
+
+```bash
+npm install @json-render/xstate-store @json-render/core @json-render/react @xstate/store
+```
+
+> [!NOTE]

+
+## Usage
+
+```ts
+import { createAtom } from "@xstate/store";
+import { xstateStoreStateStore } from "@json-render/xstate-store";
+import { StateProvider } from "@json-render/react";
+
+// 1. Create an atom
+const uiAtom = createAtom({ count: 0 });
+
+// 2. Create the json-render StateStore adapter
+const store = xstateStoreStateStore({ atom: uiAtom });
+
+// 3. Use it
+<StateProvider store={store}>
+  {/* json-render reads/writes go through @xstate/store */}
+</StateProvider>
+```
+
+## API
+
+### `xstateStoreStateStore(options)`
+
+Creates a `StateStore` backed by an `@xstate/store` atom.
+
+#### Options
+
