Hi Dirk > Yes. And I follow upstream. They didn't change :-/
Right, so please speak to your upstream. Dropping (or renaming) a symbol is changing the ABI in a backward-incompatible way, and they need to bump the SONAME (or revert the change). This is not something Debian-specific, this is how shared objects in Unix work [1][2].
