Historic development of Haskell
The Haskell 98 report was released in February 1999; it is a refinement and simplification of Haskell 1.4. See the Haskell 98 page for more details on Haskell 98 and changes from Haskell 1.4.
The definition of Haskell version 1.4 was finished in April 1997. It contains just minor changes with respect to version 1.3 from May 1996, whereas the step from version 1.2 to version 1.3 was quite large.
