While that's true, the incompatible changes to AMI, AGI, and other
non-C interfaces should all be documented in UPGRADE.txt, which
users have been asked to read.

Internal C APIs are quite a different matter, of course.  Sometimes the
interface simply must change, even in minor upgrades, in order to fix
bugs.  That is unavoidable.  The best way about this is that if you've written
an app in C, you should genericize it to be useful to others and contribute it
back upstream.  Once it's in Asterisk, you no longer need to worry about
keeping the interfaces in sync -- the developers will do that for you, as an
integral part of the changeset.
