So, how much "evolution sucks" verbiage was generated by the people running the pre-1.4.1 versions? Was there any notice that people should re-run their experiments due to a pretty drastic change in program behavior?

To be fair (to a shoddy program? How odd), v. 1.4.1 still "demonstrates" all the genetic entropy problems that Sanford makes noise about. Whatever they fixed in terms of beneficial mutations, our runs at TWeb using 1.4.1 indicate that it's nowhere near enough; a 90% beneficial mutation rate with default "maximal benefit effect" still reduces fitness in a linear manner.
