Hi guys,
version 2 adds support for multiple locations.
If you are updating this block, you also need to delete the original settings.php file in the Meteogram block folder and set up the block again, the original settings file is NOT compatible with this update.
If you only specify one location, no select box will appear. If you specify more than one, you will see a select box, where the first location in your settings will load by default.
Enjoy
