|Amphoe in Yala before the change|

Yala province has created 2 new district named Kota Baru district split from Raman district and Lam Mai district split from Mueang Yala district. Effective April 2 2015.
[...] โดยออกเป็นพระราชกฤษฎีกา (พ.ร.ฎ.) ขณะนี้ เรื่องดังกล่าวจึงยังอยู่ในกระบวนการของกรมการปกครอง
The Royal Decree on this issue is still in processing by the officials.
The article then continues by giving the rationale for this change - both districts having lots of subdistricts and have their population grown, making it more comfortable for the citizen to have the administration split, and finally mentions that the names of these districts are not finalized yet, a royally bestowed name may be chosen instead of using the name of the central subdistrict.
It is a bit strange that this change was so completely unnoticed by any other Thai newspaper, as really no other online resource picked up that report, even on the website of the province a meeting from January is the only google hit. However, I currently cannot access that website, don't know why but for several months already several government websites are inaccessible. I still hesitate to modify the corresponding Wikipedia and Wikidata entries until the Royal Decree has been published, but now have to prepare the vector maps with the new boundaries. And I hope that the Department of Local Administration will update their list of the ccaatt codes soon, right now I had to invent codes for my XML file - I gave Lam Mai the 9509 and Kota Baru the 9510, and kept the subdistrict order same as it were in their previous districts.
