 ### General changes

-One of the largest performance bottlenecks of the legacy DevTools extension was the amount of message it sent across its "bridge" (an abstraction around e.g. `postMessage`). The primary goal for the DevTools rewrite was to drastically reduce this traffic.
+The legacy DevTools extension used to add significant performance overhead, making it unusable for some larger React applications. That overhead has been effectively eliminated in version 4.
 
-The legacy DevTools also rendered the entire application tree in the form of a large DOM structure of nested nodes. A secondary goal of the rewrite was to avoid rendering unnecessary nodes by using a windowing library (specifically [react-window](https://github.com/bvaughn/react-window)).
