What are the new rules regarding the Ed visa extension in Thailand?

Ed visa - new rules.

Previously at the end of your Ed visa(360 days), you had your visa, date stamped with the date you are leaving Thailand, free of charge.

I have been advised new rules state that at the end of your last 90 day extension(360th day), you must pay 1900 baht for a 7 day extension , before leaving Thailand on the same date your Ed visa was stamped upon entering Thailand the previous year.

The attached doc dated October 2018, from Thai embassy in Laos states 1 Ed visa per calendar year.
