Release notes

0.9999.0

HBC 0.9999.0 is the first relase of hbc that supports Haskell 1.3. It is rather preliminary (as the Haskell 1.3 report is barely available), and I expect a new version to appear rather soon if there any problems.

Supports full Haskell 1.3.
Extension: Allows local universal and existential quantifications vis data type declarations.
Extension: Calling C is possible with a ccall mechanism.
Many useful libraries included.
The interactive system can now load shared libraries so it works on more platforms again.
Code generator for HPPA.
And it still compiles Haskell 1.2, of course. Use the -1.2 flag.

0.9999.1

HBC 0.9999.1 is a bug fix and minor update release. There are no new features.

HTML documentation included.
Several bug fixes relating to existential and universal quantification.
Fix some minor Prelude discrepancies.
Update the Haskell library to the latest version (dated July 18).
Minor changes to make it compile on more platforms.
Several minor bug fixes.

0.9999.2

There are two new features in this release:

A Windows 95/NT version. This is the real reason for a new release. There is only a batch compiler and it uses the CYGWIN32 package.
Floating point printing is neater and faster.

0.9999.3

Several minor (but irritating) bugs fixed.

This is a source only release.

Make binaries much smaller by splitting some libraries.
Handle newtype with a function RHS correctly.
Fix tyvar name capture problem in instance declarations.
Fix bug in typechecking of local universal quantification.
Even nicer printing of floats.
Module Trace is back!
State.sameVar works now.

0.9999.3

Several minor (but irritating) bugs fixed.

This is a source only release.

A working fromRational (finally).
Some type checker bugs fixed.
Internal changes to the State library.
Timezone bug fix in Time.

0.9999.4

This release follows the Haskell 1.4 definition.

Initial implementation of views, as suggested by Burton, Wadler, et. al.
Time zones handled in a more sane way.
Yet another bug with local universal quantification and contexts fixed.
Allow a subset of the constructors/methods to be exported. Subset import is not yet implemented.
Expand list comprehension syntax to monads.
Update libraries to official version.
formatCalendarTime function similar to strftime(3) added to Time module.
Rudimentary Locale module added.
Deriving of Read now works for labelled fields.
The environment variable HBCDIR should now work.
The interactive system attempts to build shared objects ``.so'' from object files automatically.
Add module for catenable lists (i.e. O(1) append).
Add binary file modes.
Several minor bugs fixed.
