This is a development release and will be more (or too?) frequently updated than the other releases. It is used for the demo's at http://aardbodem.nl with a PostgreSQL database.
The release of 6 July is the first one that can coexist with the separate OpenLayers module. This implies that the upgrade must be done carefully by deleting at least the openlayers folder under mappingkit before installing. The mappingkit openlayers.module has been renamed to mappingkit_openlayers.module.
Please empty the cache at /?q=admin/settings/performance when installing a new version!
