# nhc98 status

The latest stable release is 1.16. The CVS development tree is now at version 1.17. Bugfixes and important changes to the system are described here for the two most recent released versions.

### nhc98 1.16 (2003-03-08) features

- New: A large subset of the base package of hierarchical libraries is now included in the build.
- New: The primitive FFI mechanism has been updated to match the latest official spec, and the full Foreign libraries are also included (in hierarchical form).
- Performance: The library function List.sortBy now uses a stable O(n log n) mergesort.
- Bugfix: nhc98 now works correctly in the presence of gcc-3.x.
- Bugfix: nhc98 once again builds on Cygwin with ghc.
- Bugfix: Numerous other small fixes, including revisions to the Haskell'98 standard.

### nhc98 1.14a (2002-08-13) features

- The only change between 1.14 and 1.14a is that the version of hmake included in the source package has been updated from 3.05 to 3.06.

### nhc98 1.14 (2002-06-14) features

- New: The Hat tracing system is now entirely separate from the nhc98 compiler. Hat can now be used with either ghc or nhc98 - you should download and build the Hat system after building nhc98.
- New: The compiler now supports a simplified version of ghc's package mechanism. No documentation yet, but Hat relies on it.
- Performance: Various patches for improved time/space usage of the compiler itself, contributed by Thomas Nordin.
- Bugfix: Various small fixes for OS environments like OpenBSD, ix86-Solaris, etc.
