Published on October 1st was the official announcement on the upgrade of the subdistrict municipality Samrong Tai (เทศบาลตำบลสำโรงใต้) to a town municipality (thesaban mueang, เทศบาลเมือง).
This upgrade was just decided in the board meeting of June 24, the announcement was signed on August 20. However the announcement does not state the date the upgrade is taking effect, it only says "ทั้งนี้ ตั้งแต่บัคนี้เป็นต้นไป" which means "effective after this announcement is published". In the board meeting however it was set to be effective on August 7.
As the upgrade was done quite recently, the website of the municipality still shows the term "thesaban tambon" (เทศบาลตำบล) in many places, it seems that so far only the page footer has been changed to "thesaban mueang" (เทศบาลเมือง) already.
Interestingly this upgrade was the latest of the newly created town municipalities, there are still several similar upgrades already decided in the board meetings which however haven't made it into the Royal Gazette - the last similar announcement dates from 2007, so all those upgrades decided in 2008 and 2009 are not yet officially announced.
