One thing I haven't noticed in either of the proposed NEWS files is
that the gnus-mail-*-method variables no longer point to a function
but rather a symbol that is used as sort of an index.  I can't believe
I'm really the only one to ever redefine the
gnus-mail-*-using-whatever to behave somewhat differently.  I've
resorted to advising the gnus-summary-mail-* functions in my nnmh
groups to get the behavior I want in sgnus.  Someone else may find
they need to do the same.
