@Maran23 I think this is pretty close to being ready to go in. At a minimum, you will need to merge master and then fix the test so that it will compile, and then create a CSR with the updated specification (I can help with that if needed). My only other suggestion was around additional tests that might be useful, but they could be done as a follow-on fix.
