Subject: Scatha 0.2.10

Hi all,

Scatha 0.2.10 is now ready for download:

http://www.glaurungchess.com

There are several improvements compared to the previous version:

Compatibility with various hardware/software combinations further
improved. I am quite sure this version will work with all Macs running
Mac OS X 10.3.9 or newer; please let me know if you have problems.

UCI configuration has finally been added. Only one little thing is
missing; support for UCI options of type "button" (most commonly
used for the "Clear Hash" option). I simply wasn't aware that this type
of option existed. It will be fixed in the next version, of course.

UCI engines can now be uninstalled, with exception of the bundled
engines (Glaurung and Scatha).

Support for cut and paste of chess positions to the clipboard. Click
on the board window, choose "Edit" > "Copy" from the menu, switch
to any application accepting text input, and choose "Edit" > "Paste".
The FEN string for the current board position will be pasted. When
copying in the other direction, you highlight the FEN string, choose
"Edit" > "Copy", switch to the Scatha application, choose
"Game" > "Set up Position", and then "Edit" > "Paste".

The "Easy Levels" menu items are deactivated for all engines which
don't support easy levels (in practise this means all engines except
Scatha 0.2.10).

Installed patches can now be easily removed again, by choosing
"File" > "Remove All Patches".

The "About Schatha" box shows the correct version number, and
also some other (not terribly interesting) information.

Engine improvements in Scatha: An ugly hash table bug in the
Scatha engine (also present in Glaurung Mainz, by the way) has
been fixed. The value of a queen is adjusted up considerably
(from 10 pawns to 12.5 pawns). Some new basic endgame
knowledge has been added; for instance Scatha finally knows
that king + minor piece vs king is a draw.
