Hi, AIR 3.7 is out but no Apache Flex compatible version yet.
http://labs.adobe.com/technologies/flashruntimes/air/ "We are continuing to release beta updates of AIR 3.7.x, including the addition of the AIR SDK for Flex developers." A little odd that they have a release version and are continuing to release 3.7 beta's IMO but at least they have stated it's coming. Thanks, Justin
