Not im aware of , or intentional changes, but there could always be bugs. Im aware of couple of macro bugs. If you can share the details (or file a github bug) I can take a lookdid something change with timers feeding macros since 4.1 i did the up date and the lights and control was fine but the macro that turns every on didn't fire not a big deal may have messed up the start of the macro turn it one and the end of day didn't run eater.
