Mentioning changes like this could give a false sense that the release
notes are the best place to look.  I can think of quite a few changes
in this line that don't get mentioned in release notes. :-)

Diffing the texi files is probably more reliable (but would still miss
things like Wilco's recent buitin_setjmp/longjmp change, which could
also be relevant to out-of-tree ports).
