Yes, and no.  Some items were added to gps_data_t,  subframe_t, and
attitude_t.  Added was orbit_t.

The source API the client sees is merely expanded, the binary API has
larger structures than before.  So new clients will not work with
old libraries.

Binary API break, not source API break.  So a bump is needed.

Rust and Go just do away with shared libraries.  Maybe gpsd should to.
