Upgrading to 0. 6 ===
When upgrading to 0 .6 from any previous version, you need to run the "database installation and upgrade" script in [http://semantic-mediawiki.org/wiki/Help:Installation#Upgrading_existing_installations Special:SMWAdmin]. Not doing this will result into fatal PHP errors. You will also need to run the "data repair and upgrade" script on the same page, which is required in order to store all coordinates so that Semantic Maps recognizes them. Not doing this will result into queries not returning any coordinates.
