Komodo 9.41

Subject: Komodo 9.41 Sun Mar 20, 2016 6:19 pm

We have just released Komodo 9.41, a bug-fix that is free to anyone entitled to version 9.4. Version 9.41 fixes two unrelated bugs that were discovered after the release of 9.4. The first is an eval bug; we estimate that the fix in 9.41 is worth about five elo points. The second is a crippling bug on the Mac version, which may also affect the Windows version, perhaps depending on hardware, GUI, and time limit. We recommend that everyone should replace 9.4 with 9.41.
For testers, we leave it to your judgment whether to start over or to merge the results of 9.41 with 9.4. We can say that the elo gain is probably in the five to fifteen range, but this may depend on time limit and hardware. We suspect that the bugfix is more important for MP tests than for single core.

Komodo 9.41 appears to be slower in reaching depth 20 than 9.4.

I can confirm there is still a problem in Komodo 9.41. We are working on a fix which we will release it once it is tested.

I am very sorry for this. It went unnoticed when we tested with very fast games (the bug takes a while to "kick in").

I request that testing groups not test 9.41 and please wait for the update once we have it.

I think it will be worth the wait.

Komodo 9.42 is now available for download, free for anyone entitled to 9.4. While version 9.41 corrected an eval bug, it introduced another unrelated bug which was very serious. Version 9.42 fixes that bug, and keeps the eval bug fix, so we expect that 9.42 will play about five elo stronger than 9.4 and should work properly on all the normal platforms, as far as we know. We urge everyone who got 9.4 or 9.41 to replace it with 9.42.
As for testers, any results on 9.41 should be discarded, while results on 9.4 were probably only crippled by 5 elo so we leave it to your judgment whether to test 9.42 from scratch or merge results with 9.4 results. But 9.41 results are worthless, the bug was huge.
Sorry for the need for two bugfixes, but we are reasonably confident that 9.42 is our best version ever.
