Earlier V20.11 EU DEM has header 23.04.2010 15:50:47 and Part Number D224900AG013. It's overall size at ~461MiB is larger [but only less compressed] than current V20.12 of ~303 MiB with header 10.01.2012 16:19:20 and Part Number D224900AG013. Since both V20.11 and V20.12 have the same ID 288 maps with the same actual mapping data, to be ultra-precise, Giomen is also totally correct in that the EU DEM is 'the same in detail since 2010'.
Lol! It really does depending on how you look at it, and what's the meaning of 'detail' because the 2 EU DEMs can be considered to be the same, or not.
