What are the current rules and fines for overstaying in Thailand as per the latest updates?

The post informs that an individual paid a 2,000 THB fine for a 4-day overstay while waiting for a repatriation flight to India. There is uncertainty regarding the amnesty extension until the end of October, with a reminder that any new announcement has not been officially published in the Royal Gazette, thus if one does not have an extension, they are considered to be on overstay, incurring fines of 500 THB per day, capped at 20,000 THB. An edit indicates that as of October 1, the amnesty was extended retroactively to September 26.
