Directly on New Year, the Population data as of December 31st 2017 was made online on the DOPA website, giving the population numbers for each province, district and subdistrict. Sadly, its not possible to link to the actual data for the whole country directly, only for each province - however, the age distribution page also shows the total population numbers.
The total population has increased to 66,188,503, an increase of 256,953 or 0.4%. One percent of the registered population are foreigners. As one can see in my spreadsheet with the numbers at province level, the biggest increase by percent was in Samut Sakhon by 2.1%, in fact all of the provinces around Bangkok gained whereas Bangkok again lost a little.

(decrease in 2004 was data correction)
As a little side-note - the population data for Saphan Sung district finally gives the codes for the two new subdistricts which were forgotten in the latest update of the ccaatt spreadsheet - Rat Phatthana got the 104402 and Thap Chang the 104403. I still have to look through the data to check whether any municipality got a new code additionally to those already in the October update.
Another thing I still have to look into is the fact that at least for some months already, the population data no longer stops at the subdistrict level but also includes the administrative villages. However, as this means a tenfold increase of data (and thus download time, and XML file size) this creates some technical problems with my processing - besides the fact that the Muban data is a bit odd in some cases I have looked into so far.
