There is no evidence that 1.0.5 is better than 1.0.1

1.0.1 performed better in WBEC against the top amateurs and some other
programs like nimzo2000.

Maybe 1.0.5 performs better against the commercial programs(I do not know) but
in order to be better you need to be able to perform better also against weaker
opponents.
