Polygon data for Belgium was updated today.
The source data is the same as before, the only thing that should have changed is that we renamed "Bruxelles-Capitale - Brussel-Hoofdstad" to "Brussels", to be compliant with Geocaching.com.
This update reduced the regions by one, since there was one geocache located in Brussels, the rest was in "Bruxelles-Capitale - Brussel-Hoofdstad". Now everything from "Bruxelles-Capitale - Brussel-Hoofdstad" was moved into Brussels as well.
