Oh, the Platform has very strict standards about APIs,

When a package may be added:

http://trac.haskell.org/haskell-platform/wiki/AddingPackages

That looks like a very solid document. Does it also apply when considering upgrading a package already in the platform to a newer version? Also, I notice that http://haskell.org/haskellwiki/Package_versioning_policy does not mention adding new instances, which caused a problem in the past. I would argue that this ought to mandate at least a new A.B.C version, if not a new A.B. -- John
