Engine : Beowulf 2.2 b4 (Fischer personality)
Authors: Colin Frayn and Dann Corbit

Changes:
v2.2b4

1. Bug fix #2 for the "Could Not Find First Ply Hash Entry!"
intermittent problem.

Made changes to hash key and forced a 'hash elements and staleness'
check after every search. (No performance hit in my tests)

2. Made some internal eval changes. Hopefully a little stronger.

3. Updated to WB2 protocol.

4. Special Intel 'auto parallelized' optimized build (libguide40.dll' included).
This means all program code loops are executed in parallel wherever
possible. The end result being faster and more efficient operation.
(That's the idea anyway!)

Changes:

v2.3b5


1. Ponder bug fixed (introduced in 2.2b4).

2. Updated to 2.3 source code and incorporated all
previous bugfixes/changes.
