A description of the current status of the various Haskell implementations is occasionally posted on the Haskell mailing list, and sometimes on comp.lang.functional. Copies of this document are often kept on the Haskell sites mentioned above. For example, this information may be found in pub/haskell/papers/Haskell.status at the Yale site (haskell.cs.yale.edu).
