Google maps API version 1 shut down on November 1

This update comes recently from the Google maps API blog (http://googlemapsapi.blogspot.com/2006/10/revision-266-of-maps-api-v2.html)... API version 1 planned to be shut down as of November 1. What this means is that there may exist some incompatibilities between v1 and v2 so developers of gmap mashups should take note - see http://www.google.com/apis/maps/documentation/upgrade.html#Incompatibilities. According to Google Maps API Product Manager Brandon Badger, improved performance will be realized by ceasing to support and sut down v1... "the benefits will outweighthe transition costs". So, if you happen to notice a mashup after November 1 that isn't performing correctly you might want to contact the developer
