that's not exactly a "breakage". An ABI breakage is when installing a new
version of the library breaks other programs that depend on it (e.g. they
crash or refuse to start, due to unmet symbols/dependencies). An API
breakage is when existing sources can't compile with the new release of
a package anymore, because some ugly things happened in the public headers.

What you described my be flagged as a regression though, I don't know
exactly; what do you mean when you say that the function may have done
more previously ? Was it even a correct behaviour ?
