Yes, I talked about the magical 400 ft “rule” before. For hobby operators it’s still just a recommendation to stay below 400 ft. It’s generally a good idea, but it is not a rule. Yet.
What has changed is the FAA is changing the “blanket” COA for commercial operators. The upper altitude is 400 ft, from 200 ft.

However, if you are operating with a Section 333 exemption, you need to get this COA into your hands before you can fly up to 400 ft.
