-Release 2.09 contains some library changes that may break programs
-using glasgow extensions. The main points:
-
- * PrimIO has been removed, replaced by IO in all places
- (including the type of C calls).
- * The types of IO and ST have changed, to make them more
- efficient. This won't bite you unless you go digging
- around in the IO or ST monads, which you shouldn't...
- * Several extension libraries have been moved to be
- compatible with Hugs. See
-
- ftp://haskell.org/pub/reid/libs971028/libs.html
-
- for the definitions of the new libraries.
- * Several of the interfaces exported by GlaExts are deprecated,
- as they have been moved into common libraries (ST for instance).
- GlaExts will eventually contain only extensions that are
- exclusive to GHC.
-
-We've also fixed several bugs, one space leak, and added better
-handling of warnings (-W, -Wall and -Wnot flags). As usual, see the
-release notes in the Users' Guide for the full story.
+GHC 3.01 is a source-only release. Major news items:
+
+ * Lots of bug-fixes for the mult-parameter type class support.
+
+ * Re-organisation of libraries, and hslibs nuked. (see the
+ release notes/documentation for the full story).
+
+ * The User's Guide is now in SGML, and the literate tools are
+ no longer required to format any of the documentation in the
+ tree, hence we removed them from the distribution.
