+## 0.7.1
+
+### Patch Changes
+
+- feat: add middleware system and content guard middleware ([#367](https://github.com/TanStack/ai/pull/367))
+  - **@tanstack/ai**: New `@tanstack/ai/middlewares` subpath with composable chat middleware architecture. Includes `contentGuardMiddleware` (delta and buffered strategies) and `toolCacheMiddleware`. Middleware hooks: `onStart`, `onIteration`, `onChunk`, `onToolPhaseComplete`, `onFinish`.
+  - **@tanstack/ai-event-client**: Initial release. Extracted `devtoolsMiddleware` from `@tanstack/ai` core into a standalone package for tree-shaking. Emits all DevTools events as an observation-only middleware.
+  - **@tanstack/ai-client**: Updated event types for middleware integration.
+  - **@tanstack/ai-devtools**: Updated iteration timeline and conversation UI for middleware-aware event handling.
