My take on it is: if you break binary compatibility, which includes
semantic dependencies, then you increment the major version number.
Otherwise you increment the minor version number.

Since the change we're talking about apparently broke binary
compatibility, it calls for a major version number change.


Protocol incompatibility requires a different method of enforcement
altogether.  Incrementing the major number of the library isn't going
to do you any good for that (7.2 clients on remote systems won't have
any idea that the libraries on the 7.3 server have changed that much).


All MHO, of course...
