Hat download page

Please note that, beginning with version 2.00, Hat is no longer distributed as part of the nhc98 compiler, but is completely independent.

The latest stable release of Hat is 2.00, available in various distribution formats (listed below). Important patches for the stable version are also provided. The development tree is at version 2.01 and is only available by CVS. Bugfixes and important changes to the system are described in the release notes for each version.

Don't forget to read the system requirements, first, and then the installation instructions.
