GWT +gmaps v3

[lumo]

Hi
i am searching up and down for the gwt integration of gmaps v3.
i have built my old map with gwt and api v2 which worked like charm.
as v3 is out for more than a year i wanted to update my code to v3 but cant find a official libary.
i found two other libraries which are supposed to work, but do not; in their messages they write that its no longer under development due official release coming soon (this coming soon message is from way more than 6 months back)

let me know where i can get the gwt-maps3 api/jar

thanks in advance
lumo
