McCain X2b Release

A fairly significant MultiPV bug was introduced recently in SF. The SF Development team fixed it almost immediately when it was brought to our attention. Naturally , this update will have the latest patches committed since X2a Release as well.

The bug is discussed here:
https://github.com/official-stockfish/S ... ssues/2092

and here:
https://github.com/official-stockfish/S ... ssues/2091

X2b source:
https://github.com/MichaelB7/Stockfish/ ... X2b.tar.gz
https://github.com/MichaelB7/Stockfish/archive/X2b.zip

Exe's will be posted on Github when available - over the next 12 to 24 hours.

Best regards,
Michael

There have been several "silent updates" to the 2.9.0 executables on the Scorpio release page that are not in the list of updates.

That's at least 10 silent updates, including the currently unlisted 22 April one, without changing version number. What happened to Scorpio's versioning system? It's creating a logistical hell for the rating lists.

Queen 4.04c from 2018 with improved GUI http://home.planet.nl/~ammeraal/chess.html

Thanks, this GUI only update helped me to fix an error in my chronology ;-)

Actually the last engine update was version 4.02 and not 4.03, what my chronology falsely claimed.
This is fixed now.

There was a 4.03a release dated 19/06/2011.

Possibly the same engine as 4.02 though.

Queen 4.03 is available from my website
http://home.planet.nl/~ammeraal/english.html
This version differs only from the previous one in the GUI.
I am grateful to Franz Huber, who found several errors in the GUI, which I have fixed.

Queen 4.02a
Thanks to Franz Huber, who reported a problem with Queen 4.02 on his computer under Windows 98 and who tested quite a few experimental versions for me, Queen 4.02a is now available, which solves this problem. Otherwise, Queen 4.02a is the same as Queen 4.02

It's not a GUI only update. 4.04c can play as a Winboard/UCI engine as well. It works for me in Arena.

Yes it can, but still the engine is unchanged to 4.02...
(GUI versions could be used at least since versions 3.x)

Axolotl 1.7 UCI folders (.zip and .tar.gz) have no Java-executable (jar) file https://github.com/louism33/Axolotl/releases

It is in the main github folder.

Edit:
Well, it is also in the release download in the root folder, you must have overlooked it.
