 Retiring a Branch
 =================
 
-After support is dropped for an old branch, remove the link for it
-in HEAD's doc/src/sgml/release.sgml.  If the newest back branch hasn't
-yet reached GA release, do the same there.  (Given our current development
-calendar, the latter should seldom be necessary.)
