Yes, but I'll hold off announcing the details until they are final. One is quite interesting in my opinion.

Appreciate :)
We added another one (the one I find quite interesting) after Jesse sent this, but we haven't finalized the name yet.

Interesting for sure.

By the way if it is true K9.4 exceling at blitz this time, it theory it may be enhanced further in case running with ponder!

Larry, one small request: all parameter names should start with Uppercase. Therefore it should be 'Suppress'.

Also, it should be 'Use LMR' and not 'Use Lmr' as 'LMR' is acronym, just as 'UCI' is.

Best

An option to use contempt only when white? If so I have a good feeling about this new feature.

I was thinking for the rating lists. Some believe a small amount of contempt with white, and no contempt with black is best.

I wouldn't say it excels in blitz, it's just been improved at all levels.

So you say it didn't improve more in blitz than usual ?

The improvements should help at all levels, but we can only verify this at blitz, it would take too long to run thousands of slow games.
