J.D. - As I understand it, as of now (things are changing fast), we will need to do the FAA online training (no charge). This only applies if you currently have a part 107 certificate. If you have not taken the initial written test, you must do that first.
If you have a part 107 and your original is not current, you only have to do the online training. Once you do that, you have also satisfied the biannual requirement to remain current. No more written ($150) tests!
Once you have your initial 107, and done the online training, you are permitted to fly at night AND over people - at this point I assume there will be some restrictions, but you need to research that.
Online training is available April 11...but this date has been moved, so may not be a “hard” date.
As mentioned, things are changing, and I’m no expert - this is just my understanding at this point.
