yes, the convention for .so dynamic libraries is supposed to be that
(using the nomenclature you give) "z" versions are compatible with
each other (zero dynamic library API changes permitted), y is where
changes to functions is permitted.

of course c++ completely ballses those conventions up at the "z" level
due to name-munging which left developers needing to do "API map" hint
files to the linker.
