That annoyed me too, mine is 1.00 and all the links for previous firmware and the aborted v1.11 are gone from the official Pentax factory sites.
....but this is another reason why Pentaxforums is great !
Adam or one of the guys posted a copy of the firmware file with the news article when it was released toghether with all the instructions.
version 1.10 is here on this page
