I've just updated the links on the F# manual pages to point to the updated draft language specification (one big HTML page, or PDF) for the 1.9.4 release.

This is a major revision of the old spec to cover much of the language work done in the 1.9.4 release. It's from us at Microsoft Research, so isn't an "official" Microsoft spec.

This includes some comments from the F# team and some working notes.
