The seventh fish is getting closer. Jim Ablett has already compiled the source code with commit number a5c76d6 of the first beta. Thanks Jim!
It would be interesting to compare these JA builds to Peter Österlund's builds released with the development version of Droidfish 1.59. Maybe some people will find enough time to conduct a head-to-head match.
I hope the official version will not delay any longer because the whole community is waiting for v7 since one year. And one year of wait, in today's scale, is like a decade of the 80's.
