... a question: Should we then change the HAK article to recommend beta5? (feel free to discuss/continue this in the Wiki Discussion forum)
Perhaps. I don't know if there is much to discuss about. I have seen very few if any valid test results that would help making the decision.
I promised to do some ABX testing when Aoyumi released b5. I actually encoded a bunch of test samples with R1 and b5. However, I couldn't quickly hear any ABXable differences and I postponed testing to some later time. Looks like that time has not come yet...
I suppose if b5 introduced any new serious problems they would have been discovered during the last few months.
