Use %{version} where appropriate
    
    Some paths contain the full version, so use the macro to allow for
    smooth updates to new upstream releases. Note that there are still
    places where the major version is used explicitly - this is intentional
    to avoid accidental soname bumps (which should happen only between major
    versions).
