Satana 2.0.4 released

[stegemma]

Satana 2.0.4 has been released, for Windows 32/64 bit.

In a gauntlet 1' against previous release it seems a little stronger (or a little less weak).

This release doesn't have quiescence search.

On my site, you can find older releases of Satana, Raffaela and Drago:

This release seems stronger than Neurone XX and Supra but weakest than AdaChess and other engines (Spyke, SOS, AnMon and so on).
