You also mentioned 'md5' in the entry about password_encryption,
remember? I tend to agree with Justin: if it's not too much extra space
to mention both values, let's just do that. "Reduce the value of X to Y
from Z. The new default better reflects ..." seems OK to me.
I prefer "to Y from Z" rather than "from Z to Y", because then the new
value appears first, which seems a tiny improvement in readability,
though the phrase is in the opposite order of traditional. Also it
seems better than "change value of X to Y. The previous default was Z"
because it then becomes a little more verbose than really needed. But
maybe that's OK too.
