I agree.  I believe that it's appropriate.  I'd be willing to see us
drop support for the 1.1.x series, for that matter.  IMO it's easier to
keep track of "1.1 is unsupported" than try to remember which monthly
release in particular is unsupported.  Agreeable policy?

Question for someone more knowledgeable: is there a brief explanation of
the difference between 1.1 and 1.2 SBCLs?  What triggered the bump of
minor version?
