Whether it's raising or lowering depends on which way we're looking at the TF limits: (a) the upper limit on power-of-two to which Prime95 TFs a given Mnumber, or (b) the lower or upper limits on Mnumber exponent for which Prime95 TFs to a given power-of-two. Recent Prime95 changes raised (a) for some Mnumber exponents, and thus lowered (b) for some powers of two.
