01 Feb '01

Dear all, I'm pleased to announce the release of ======================================== O'Hugs 0.5 -- the O'Haskell interpreter. ======================================== O'Haskell is an object-oriented extension to Haskell, offering monadic reactive objects and polymorphic subtyping in addition to the Haskell core. O'Hugs is an implementation for this language. New features in O'Hugs 0.5 include: - A more refined interface to Tk, including support for the optional Tk extension Tix. - Support for network programming via TCP and UDP. - Much improved library documentation. - Local universal quantification in records. - Local existential quantification in datatypes. - Templates with automatic instantiation of local sub-objects. - Overloading using smallest supertypes for contravariant type classes. - Recursive generator syntax. - Macintosh and Windows binaries. - Several bug-fixes. For more information and dowload options, please visit http://www.cs.chalmers.se/~nordland/ohaskell/ Bug reports and comments should be sent to nordland(a)cse.ogi.edu. Enjoy, Johan Nordlander PS Please don't confuse this release with today's concurrent release of a new beta version of Hugs98!
