We have never guaranteed that a dissector built for Wireshark major version 1.x will work with the development version 1.{x+1} or the next major release 1.{x+2}.  We only guarantee that a dissector built for 1.x will work with 1.x.y, i.e. that stability will be preserved for all minor releases corresponding to a given major release.

It takes more than just stable function names for a stable API.  It requires that:

	for any function, its signature not change (no added or removed parameters);

	no function be removed;

	no incompatible change to any arguments for a function be made.
