I agree with Eric here, new directives are sometimes the way to fix
something for those who need to, without breaking the others that
By the way, if we bump minor for any non-forward-backportable change,
who is going to maintain all the "current minor minus n" versions
while all of the new/fancy things are in current only (and minor keeps
I'm afraid it won't help users stuck at some minor version (because of
API/ABI) if they don't get bugfixes because their version doesn't get
IOW, what maintenance would we garantee/apply for some minor version
if we keep bumping minor numbers to get new stuff out?
Not an opposition, just wanting to have a clear picture. Remember that
some/most? of us have never been actor in a new httpd minor release,
not to talk about a major one ;)
