 #### Resource API
 For better automatic hydration support it is prudent to change resource signatures to take functions that return promises rather than promises themselves. This factory function has a lot advantages. This allows the library to decide whether to execute it or not. In certain cases we can choose skipping creating the promise altogether. It also leaves the door open for things like retry.
 
+We use this mechanism to wire up streamed data from the server and automatic data hydration for resources rendered into the page in async SSR.

 #### SSR Improvements
 
 New experimental support for Suspense aware synchronous, asynchronous, and streaming SSR with hydration, progressive hydration, and automatic isomorphic data serialization. Completely removed what was there before with a simple static generator and more examples, so all existing projects using `solid-ssr` package will break with this release. This is a much better foundation, and I hope to build better things on top.
