Version 0.7 is the last stable release. It should be compile with GHC
6.4.2 and earlier. The version in base corresponds to this version, with
one or two safety tweaks (unfortunately).
Version 0.8 is the unreleased darcs version, to be merged into base, in
a week or two (after we replace the array fusion system).

As far as I know it has not yet been decided to split it out.
We'll be tagging and released fps 0.8 (only for ghc 6.4.2 and earlier),
and the same code wil appear in base, in a couple of weeks, hopefully.

The other compilers should be using a base package with fps in it, as
hugs and ghc do.
fps as a package only exists as a seperate darcs repo for those systems
that don't have bytestrings in base. I.e. older GHC's, and nhc98 (not
Hugs or GHC 6.6).
Does that help clear things up? Effectively there is *no* fps package
really -- its suppposed to be part of base, as ghc and hugs have it.
