Do I need to return to immigration for a stamp if my visa extension expires before I leave Thailand?

The discussion revolves around whether someone with a visa extension stamp until October 11 must visit immigration again after a new amnesty was announced extending the stay until October 31, especially if they plan to leave before this date. Comments emphasize the importance of the expiration date on the current stamp, suggesting that if leaving before that date, no action is needed, but if leaving after, one should go back for an updated stamp.
