changes:

Code:

23.5
Several pieces of code cleanup, both for readability and speed. 
We are now using stdint.h, which lets us specific the exact size 
of an integer value which gets rid of the int vs long issues that
exist between MSVC and the rest of the world on X86_64.  We still
use things like "int" if we want to let the compiler choose the 
most efficient size, but when we need a specific number of bits, 
such as 64, we use a specific type (uint64_t for 64 bits).  Minor
change to forward pruning that does not toss out passed pawn     
moves if they are advanced enough (compared to remaining depth) 
that they might be worth searching.  Cleanup to passed pawn eval 
code to help efficiency and readability.  New options to the     
display command.  "display nothing" turns all output off except 
for the move Crafty chooses to play.  "display everything" will 
produce a veritable flood of information before it makes a move. 
Cleanup of personality code to fix some values that were not     
included, as well as clean up the formatting for simplicity.

This is probably pointless for most people, except those who really get confused by Wb2uci, but I managed to compile a working Crafty 23.5 32 bit Uci version using the same method I used above i.e Wb2uci + Crafty.exe packaged in one executable. Don't ask for a 64 bit version - it didn't work.

Crafty 23.6
- this is a source-code-only release
- "my personal testing shows an increase of roughly +52 Elo"
http://www.kikrtech.com/files/crafty-23.6.zip
http://www.cis.uab.edu/hyatt/crafty/source/crafty-23.6.zip

Code:

Changes:

 *    23.6   Minor tweak to "adaptive hash" code + a fix to the usage warning  *
 *           that failed to explain how many parameters are required.  New way *
 *           of timing the search, replacing the old "easy move" code that was *
 *           simply too ineffective.  Now Crafty computes a "difficulty" level *
 *           after each iteration.  If the best move doesn't change, this      *
 *           level is reduced by 10% of the current value, until it reaches    *
 *           60% where it stops dropping.  If the best move changes during an  *
 *           iteration, it adjusts in one of two ways.  If the current         *
 *           difficulty level is less than 100%, it reverts to 100% + the      *
 *           number of different best moves minus 1 times 20%.  If the current *
 *           difficulty level is already >= 100% it is set to 80% of the       *
 *           current value + (again) the number of different best moves - 1    *
 *           times 20%.  Repeated changes can run this up to 180% max.  As the *
 *           search progresses this difficulty level represents the percentage *
 *           of the nominal target time limit it should use.  It still tries   *
 *           to complete the current iteration before quitting, so this limit  *
 *           is a lower bound on the time it will use.  Restored an old idea   *
 *           from earlier Crafty versions (and even Cray Blitz), that of       *
 *           trying the killers from two plies earlier in the tree, once the   *
 *           killers for the current ply have been tried.  Was a +10 Elo gain, *
 *           added to about +10 for the new time control logic.  Old fail-high *
 *           restriction removed.  At one point in time, a fail-high on the    *
 *           null-window search at the root would cause problems.  Crafty was  *
 *           modified so that the fail-high was ignored if the re-search       *
 *           failed low.  Removing this produced an 8 Elo gain.                *
 *                                                                             *

The links You placed are only to download the source files of Crafty, do You have a link to download the engine itself?
Thanks in advance

dear friends .. I wonder when will it be released some crafty UCI would be good for people like me who have only fritz gui ... that only accepts uci engines, use fritz interface because it is beautiful, clean, efficient, and very effective, when oncoming motor winboard .. ask to put UCI adapters also ... unfortunately did not know to put myself ... but also here is my protest ... since this wave is best ...

You will find that "full" is equal to "speed" for me

Full feature builds have all options enabled: EPD support,
