The flagship feature of React 19 is a "compiler", but doesn't seem to have the main features of Forget. (inferred effect dependencies) I'm guessing it's not coming any time soon.
React 19, a library release, is completely separate from the eventual release of the React Compiler build tool (which is currently implemented as a Babel plugin wrapper around a full compiler implementation core).
That said, React Compiler will _depend_ on React 19, because it needs a new memo/caching hook that will be included in 19.
