I’m wondering whether extension libraries compiled against 1.8 will work
with 1.9, and/or the other way around.
I know the C API is little-changed, but will people offering add-ons
binaries need to offer two versions?
Also - if it should work, should I be worried about a particular library
if it’s not currently working - or just be patient and assume it’s down
to 1.9 being work in progress?
