"Open Galaxy" is replaced by "Galaxy". Click it and there's "Open Galaxy" and "Create a new Galaxy/Zone", and potentially "Galaxy Properties" in the future.
When you click Create a new Galaxy/Zone, a window appears with checkboxes of what layers you want it to have and the internal name. There are also checkboxes of what files you want to generate (Map, Scenario, Design, Sound, ZoneInfo). Map and Scenario are checked by default.
