Main change probably affecting you is the update from sdformat9 to sdformat12 which, indeed, has some improvements that generates some incompatibilities. SDFormat has its own migration guide. I sometimes found useful to run ign sdf --check (ignition-tools package) to get some hints about what's going on.
