+External state store, store adapters, and bug fixes.
+
+### New: External State Store
+
+The `StateStore` interface lets you plug in your own state management (Redux, Zustand, Jotai, XState, etc.) instead of the built-in internal store. Pass a `store` prop to `StateProvider`, `JSONUIProvider`, or `createRenderer` for controlled mode.
+
+- Added `StateStore` interface and `createStateStore()` factory to `@json-render/core`
+- `StateProvider`, `JSONUIProvider`, and `createRenderer` now accept an optional `store` prop for controlled mode
+- When `store` is provided, it becomes the single source of truth (`initialState`/`onStateChange` are ignored)
+- When `store` is omitted, everything works exactly as before (fully backward compatible)
+- Applied across all platform packages: react, react-native, react-pdf
+- Store utilities (`createStoreAdapter`, `immutableSetByPath`, `flattenToPointers`) available via `@json-render/core/store-utils` for building custom adapters
+
+### New: Store Adapter Packages
+
+- `@json-render/zustand` — Zustand adapter for `StateStore`
+- `@json-render/redux` — Redux / Redux Toolkit adapter for `StateStore`
+- `@json-render/jotai` — Jotai adapter for `StateStore`
+
+### Changed: `onStateChange` signature updated (breaking)
+
+The `onStateChange` callback now receives a single array of changed entries instead of being called once per path:
+
+```ts
+// Before
+onStateChange?: (path: string, value: unknown) => void
+
+// After
+onStateChange?: (changes: Array<{ path: string; value: unknown }>) => void
+```
+
+### Fixed
+
+- Fix schema import to use server-safe `@json-render/react/schema` subpath, avoiding `createContext` crashes in Next.js App Router API routes
+- Fix chaining actions in `@json-render/react`, `@json-render/react-native`, and `@json-render/react-pdf`
+- Fix safely resolving inner type for Zod arrays in core schema

 The callback is only called when a `set()` or `update()` call actually changes the state. A `set()` call produces a single-element array; an `update()` call produces one array with all changed paths.
 
+### Fixed: Server-safe schema import
+
+`@json-render/react` barrel-imports React contexts that call `createContext`, which crashes in Next.js App Router API routes (RSC runtime strips `createContext`). All docs, examples, and skills now import `schema` from `@json-render/react/schema` instead of `@json-render/react`.
+
+For combined imports, split into separate `schema` (subpath) and client API (main entry) lines:
+
+```ts
+import { schema } from "@json-render/react/schema";
+import { defineRegistry, Renderer } from "@json-render/react";
+```
+
+### Fixed: Chaining actions
+
+Fixed an issue where chaining multiple actions on the same event (e.g. `setState` followed by a custom action) did not execute all actions. Affected `@json-render/react`, `@json-render/react-native`, and `@json-render/react-pdf`.
+
+### Fixed: Zod array inner type resolution
+
+Fixed safely resolving the inner type for Zod arrays in schema introspection, preventing errors when catalog component props use `z.array()`.

 ### New: `@json-render/react-pdf`
 
 PDF renderer for json-render, powered by [`@react-pdf/renderer`](https://react-pdf.org/). Define catalogs and registries the same way as `@json-render/react`, but output PDF documents instead of web UI.
