v17.1.0.rc.2

Fixed

• [Pro] Prerender-cached streamed renders now hydrate on every request: The automatic prerender cache key
  deliberately ignores random dom ids so one cached render serves every mount point, but the cached
  chunks still embedded the first request's dom id in their React Server Component payload keys.
  Every cache hit therefore refetched the payload and failed hydration whenever the render was not
  byte-identical. Cached streams are now rebound to the dom id of the render being served. Fixes
