 <!-- RELEASE_SCRIPT_TOKEN -->
 
+## 4.22.0 (December 13, 2021)
+
+#### A note for React Native users
+React DevTools has [two main pieces](https://github.com/facebook/react/blob/main/packages/react-devtools/OVERVIEW.md#overview):
+* The *frontend* users interact with (the Components tree, the Profiler, etc.).
+* The *backend* which runs in the same context as React itself. (In the web page with React DOM or shipped on the device with the React Native runtime.)
+
+This release updates the [**protocol** that DevTools uses](https://github.com/facebook/react/blob/main/packages/react-devtools/OVERVIEW.md#serializing-the-tree) to communicate between the "frontend" and "backend" components.
+
+Because React Native embeds a copy of the React DevTools "backend" ([`react-devtools-core/backend`](https://www.npmjs.com/package/react-devtools-core)), the "frontend" (UI) needs to match. This means you may be prompted to upgrade (or downgrade) your React DevTools based on which version of React Native your app uses.
+
+#### Features
+* Support multiple DevTools instances per page ([@bvaughn](https://github.com/bvaughn) in [#22949](https://github.com/facebook/react/pull/22949))
+* Advocate for StrictMode usage within Components tree ([@bvaughn](https://github.com/bvaughn) in [#22886](https://github.com/facebook/react/pull/22886))
+* StyleX plug-in for resolving atomic styles to values for props.xstyle ([@bvaughn](https://github.com/bvaughn) in [#22808](https://github.com/facebook/react/pull/22808))
+* Timeline search ([@bvaughn](https://github.com/bvaughn) in [#22799](https://github.com/facebook/react/pull/22799))
+* Add test selectors to experimental build ([@bvaughn](https://github.com/bvaughn) in [#22760](https://github.com/facebook/react/pull/22760))
+* Timeline: Improved snapshot view ([@bvaughn](https://github.com/bvaughn) in [#22706](https://github.com/facebook/react/pull/22706))
+* Display root type for root updates in "what caused this update?" ([@eps1lon](https://github.com/eps1lon) in [#22599](https://github.com/facebook/react/pull/22599))
+* Add open in editor for fb ([@ezzak](https://github.com/ezzak) in [#22649](https://github.com/facebook/react/pull/22649))
+
+#### Bugfix
+* DevTools should inject itself for XHTML pages too (not just HTML) ([@bvaughn](https://github.com/bvaughn) in [#22932](https://github.com/facebook/react/pull/22932))
+* Don't restore profiling data if we're profling ([@eps1lon](https://github.com/eps1lon) in [#22753](https://github.com/facebook/react/pull/22753))
+* DevTools should properly report re-renders due to (use)context changes ([@bvaughn](https://github.com/bvaughn) in [#22746](https://github.com/facebook/react/pull/22746))
+* Filter empty commits (all Fibers bailed out) from Profiler ([@bvaughn](https://github.com/bvaughn) in [#22745](https://github.com/facebook/react/pull/22745))
+* Accept json file in import fileinput ([@jyash97](https://github.com/jyash97) in [#22717](https://github.com/facebook/react/pull/22717))
+* Expose css vars to reach-ui portal components ([@jyash97](https://github.com/jyash97) in [#22716](https://github.com/facebook/react/pull/22716))
+* Fix DevTools advanced tooltip display conditional check ([@bvaughn](https://github.com/bvaughn) in [#22669](https://github.com/facebook/react/pull/22669))
+
+
+#### Misc
+* Internally log errors occurring or reported to the frontend ([@jstejada](https://github.com/jstejada) in [#22948](https://github.com/facebook/react/pull/22948))
+* Emit new event when DevTools connects in standalone app ([@jstejada](https://github.com/jstejada) in [#22848](https://github.com/facebook/react/pull/22848))
+* DevTools: Log version in internal logger ([@jstejada](https://github.com/jstejada) in [#22825](https://github.com/facebook/react/pull/22825))
+* Proof of Concept for E2E tests using playwright ([@akgupta0777](https://github.com/akgupta0777) in [#22754](https://github.com/facebook/react/pull/22754))
+* Add internal link to Scheduling Profiler ([@bvaughn](https://github.com/bvaughn) in [#22730](https://github.com/facebook/react/pull/22730))
