You get paid, we work for free?  Does not seem fair.  Try to give back
in some way on the future.

That is NOT an error, read what it says.  You have an API mismatch, and
you either need to change your code for the new API, or stick with the
old gpsd.

Only if you want your code to work.  But the versions mean something.
So you have to change your code to match the versions.

If you access a gpsd with its matching libgps, then most version
changes will be invisible to you.  Most of the remaining ones
will give you compile errors.  What remains will be a few visible
behavior change.

They tend to go in tandem, but they can differ.

Not much I can do without seeing your code.
