What are the new visa rules for Russian nationals entering Thailand?

This is the published order that as in effect tomorrow Russian nationals will get a 60 day stamp on arrival - a change from the previously granted 90 days.

At this point in time it is unclear whether they can still opt for a 30 day entry (and therefore get an extension and possibly change to another type of visa in country - which they could not with a 90 day entry) or not. I will update when I hear more.
