I guess that the next version is going to have more moves in book but every move that is going to be added is going to be added manually and I am not going to put there more than 100 moves. I did not decide about the time of the release of the next version and I guess that I am going to release it only after I have a version that gets at least a result of 24-16 against movei007a with no book and always changing the first move(it means that with white I start 1.a3,1.a4....1.h3,1.h4,1.Na3,1.Nc3,1.Nf3,1.Nh3 and with black I start 1...a6 1...a5,...) I am also going to correct some bugs in the next public version that I do not consider as very important(I have already a version without the bugs but I prefer not to release a version that I did not do a lot of games with it because it may have other problems that I do not know about) The known bugs that I talk about are: 1)it declares mate in stalemate positions and crush(usually you are not going to get stalemate positions against it). 2)It does not say mate after playing the checkmate. 3)It believes that the maximal number of bishops or knights is 9 when it is really 10(does not cause problems in games but caused a problem in a test position for stability). It may also crush in very long games of more than 1000 plies(maybe even more than 750 plies are enough and I am not sure at this moment) but it never happened in games(there were games of more than 200 moves but it never played a game of more than 300 moves). I know that there are engines that are clearly less stable than movei(engines in Leo's tournamet sometimes lose on time or do an illegal move when until today it never happened to Movei in Leo's tournament. note that Movei ignores castling rights and en passant in it's repetition detection but it was never a problem even in one game out of hundreds of games(I guess that I will also correct the problem in the next version but it was not in my priotities until today).
