An update of the Spanish polygons is in progress. The polygons are already there, the servers are currently calculating the location of the 80000 geocaches there.
Differences that we noticed:
* Some counties did not exist in our old polygons. Very unsure why, they should have been there.
* Borders might have been slightly adjusted, nothing we could see clearly. But the data dump was 31 MB instead of 30 MB.
We did not notice any changes regarding regions.
