 * Fixes NS1 provider's geotarget limitation of using `NA` continent. Now, when
   `NA` is used in geos it considers **all** the countries of `North America`
   insted of just `us-east`, `us-west` and `us-central` regions
+* `SX' & 'UM` country support added, not yet in the North America list for 
+   backwards compatibility reasons. They will be added in the next releaser.
