IE6が Google Maps API v3のサポート対象外になった

Google Geo Developers Blog: Supported browser updates for Maps API v3

As we look ahead it is clear that HTML 5 offers us the platform we need to deliver on this vision. However as we develop features that exploit the potential of HTML5 it will not be possible to maintain our current level of support for older web browsers. For this reason we will be updating the list of supported browsers for the Maps API v3 on a regular basis. We are applying our first update today by removing Firefox 2, Internet Explorer 6, and Safari 3, while adding support for the Android browser and for Chrome on Mac and Linux.

なるべく動くようにはしたいんだけどねー的なことらしい。
V2の方はまだサポートしてるし、変える予定もないとのこと。
