Aug. 25, 2006: m5_2.0_beta patch 1
--------------------
Handful of minor bug fixes for m5_2.0_beta,
along with a few new regression tests.

Aug. 15, 2006: m5_2.0_beta
--------------------
Major update to M5 including:
- New CPU model
- New memory system
- More extensive python integration
- Preliminary syscall emulation support for MIPS and SPARC
This is a *beta* release, meaning that some features are not complete,
and some features from M5 1.X aren't currently supported (e.g., MP
coherence).  We are working to address these limitations and hope to
have a complete 2.0 release soon.

- Several bug fixes and better compatibility for Cygwin hosts
- Major cleanup of Alpha system code (console, PAL, etc.) to make
  it easier for others to build/modify
- Fixes to enable compilation under g++ 4.0 
- Numerous minor bug fixes
