Darek,
Honestly, we can't be sure for V14.6, but it's safe to say that while things have changed since then, the standard drilling and pecking were always there working fine in Single Step or Auto mode. A bunch of other G codes can be found in the MACRO.MAC file as well as the DEFAULT.CBK.
Z moves, offsets after tool changes in any mode are working fine. No problem reported with these. GW has the new stuff try it out when you get there.
