DieHard release notes
---------------------
version 1.2:
* Added 64-bit support.
version 1.1:
* Dramatically reduced memory consumption.
* Fixed logic (for Windows) that protects against double free errors.
* Fixed the MWC random number generator, enhancing randomness.
* More robust whitelist processing for DieHard system, for
Windows protection.
release 1.0.2:

and prevents certain errors.

release 0.3 (December 28, 2005):
* Added "red zones" around heap metadata to prevent
corruption by buffer overflows.
* Added support for Microsoft Visual Studio 2005.
* Changed behavior of DieHard to initialize unallocated
memory to zeros (standalone version only).
release 0.2 (December 2, 2005):

multiprocessor/multicore platforms.
* Ported to Solaris Sun Workshop compilers.
