June 3, 2010 Onno goes Facebook. Become a fan of Onno Chess Engine on Facebook to see what I am currently working on. Of course, I will continue to announce updates and other major news on this webpage, so those who are not on Facebook don't miss important news.
Mai 29, 2010 An experimental native Linux version is available on the download page.
Mai 15, 2010 Onno 1-2-70 is out. This is the final (non-beta) MP update. For existing customers it is available on the download page.
In my tests, on 2 cores, Onno was 65 Elo above the single version. On 4 cores, Onno was 116 Elo above the single version. These first results need further verification.
There are also some minor changes to the single version, but there there is no measurable difference in playing strength. Development of Onno will continue with improvements of the playing strength.
Apr 26, 2010 The final MP update was scheduled for yesterday. Unfortunately the last tests have shown some problems, so I cannot release the current development version. So I decided to release the last stable version, 1-2-6. It is available on the download page. The final MP update will follow later.
Feb 24, 2010 A beta of the multi processor version is available on the download page.
As promised the download is free for existing customers. New customres can buy Onno at share-it.
Feb 11, 2010 Some words on the MP version: First I have to appologize for the delay. I know that many people are waiting impatiently for the MP version.
There are many reasons for the delay, ranging from unexpected changes in private life to the underestimated complexity. But one thing is not among the reasons: Lack of willingness to finish the MP version.
Currently I have something that is supposed to be complete, but it is hardly tested. The next step is to run basic tests on my side. As I don't know how many problems I will discover, it is difficult to give a release date. Please don't ask for a beta, this would be too early.
Dec 25, 2009 I gave an interview in the Schach-Welt (in German).
Oct 8, 2009 After Onno has promoted through all class into Chess War A, Naum and Onno finish as second and third with 10 out of 15 each. Winner is Rybka. Virtually all engines are involved in the Chess War league system. See the Chess War site for the complete results.

After several attempts to get the newsletter system of share-it working properly, I decided to give up now. I will not send more newsletters for some time. I no longer check or add users manually. My medium-term plan is to set up my own newsletter system.
Aug 29, 2009 Release of Onno 1-1-1. This is the tablebase update.
Jul 16, 2009 Release of Onno 1-0-4. Most important changes are a bugfix with hashing in endgame and reduced sensitivity to installation problems. The download link was sent by newsletter to all who registered for it.
