I am getting a lot of inquires about the next version so I will answer them here.
Unfortunately I stopped working on Naum in January. Last 2 years I quit my job and dedicated all my time to the engine development. It became more of a job and less the hobby so I just burnt-out and completely lost desire to continue. This is the main reason why I didn't participate in CCT and have no plans to attend any of the tournaments this year. If one of the customers wants to enter some of them, this is fine by me.
I still plan to release an update this year, since there is a bunch of ideas waiting and hopefully I will get some motivation to work on them.
Since I plan to return to my regular job, there won't be much time left for the future development, but I may still be able to do some work from time to time. Future versions (if any) will most likely be distributed as free updates to Naum 4 customers. I doubt there will be a new commercial release unless I get lucky and get a big improvement with a little work.
I know this comes as a disappointment to some who hopped that Rybka domination can be stopped, but Vas is just too good

I have high hopes for Thinker based on its rapid rate of improvement and hope it continues. I also think SMK may still be able to pull a couple of surprises in the following years with Shredder. Wouldn't discount Sjeng too, since GCPs desire to win is bordering madness

Thanks a lot to all who have supported me over the years,
Alex
