Test Changes for 2019 (i.e. Op. Leases)

Hello - assuming this has already been asked (didn’t see it in my quick search though), but does anyone have a summary of the changes for the 2019 test? Specifically am looking for changes for operating leases as these are now being added to the balance sheet. Asking as I’m using a set of 2018 KS books that obviously do not reflect the change. Just want to make sure I’m prepped for these questions on the test (assuming there will be 1-2 given the change).

Thanks - CFAPrep2019
