Admited Until Stamp - After Renewing Retirement Extension

[KED]

Just to make sure all is ok, I entered Thailand last month on a one-year extension based on retirment and a multiple re-entry permit. My entry stamp was until 11Nov12 - today I went to Chaeng Wattana and received a new extension and re-entry permit valid unitl 11Nov13 -

But my entry card and stamp still show 11Nov12 - do I need to get a new stamp showing entry until 11Nov13 or is the new extension stamp sufficient ?

Also, just to add to the continued subject of any extra requirements outside of the stated rules. I hold a U.S. passport and used a notarized letter from the U.S. Embassy verifying my monthly income in excess of THB 65,000.

I was not asked for a bank book nor a verification of address or any other documents except the letter and copies of my passport.

The extension is of that entry so no you do not need anything else.
