Hi all :-),
our rating lists are now online and can be found under the attached links.

40 / 20:
Today we added 1210 games made with 47 different engines to our list. See more in our list "Games of the week". In total our 40/20 list is based now on  386.652 games.

New engines:

We have just started with Deep Fritz 12: With 4CPUs the engine reached 3074 elos in 140 games. This is a good start with +55 to Deep Fritz 11.
Umko 0.7 x64 has had a good start too: 2747 elos in 180 games!
Arasan 11.7 x64 1CPU has had a good start against Critter 0.40 - but lost a lot of more games against the other opponents compared to version 11.6. So it seems there is no progress: 2560 Elos in 352 games are 19 points behind version 11.6 now.

Updated engines:
29 Naum 4.1 x64 1CPU 2999 +19 -19 713 games (-1)
198 Critter 0.52b x64 2841 +15 -15 1200 games (+-0)
241 Twisted Logic 20100131 x64 2810 +21 -21 716 games (-1, +5 to previous version)
323 Scorpio 2.5 x64 1CPU 2724 +23 -23 580 games (-6)


Blitz Update
New games: 7360
All games: 596.280

New engines

New in the list is Stockfish 1.6.3 x64 4CPU with 3140 elo/ 800 games. This is very close to version 1.6 - maybe there is really no difference in strength.
Another new entry is Twisted Logic 20100131x x64 with 2803 elos in 1000 games and here too only a few points ahead of previous version.
A very good start has had Umko 0.7 here too in our Blitz list. The engine makes no more problems and reached 2755 elos for 64bit and 2678 elos for 32bit-version.
Arasan was tested in 2 new versions:
Arasan 11.7 x64 1CPU with 2600 elos in 1000 games and
Arasan 11.3 w32 1CPU with 2471 elos in 500 games.
We also started to test Philou 3.1.0: 2460/360 games - around 100 points better than version 2.8.0 in our list.

Updated engines:

7 Naum 4.1 x64 4CPU 3160 +31 -31 250 games (+49)
21 Naum 4.1 w32 2CPU 3048 +15 -15 1300 games (-8)
37 Naum 4.1 x64 1CPU 3015 +15 -15 1250 games (+-0)

197 Critter 0.52b x64 2852 +16 -16 1200 games (-6)

That's what the developers said, they were only bug fix releases not meant to improve strength, perhaps all the games of 1.6, 1.6.2 and 1.6.3 can be merged.

i believe multi-core implementation was improved,at least 8 cpu implementation.however as no testing site tests 8 cpu,i agree with you,they can be merged.
