Adobe announced the availability of AIR 1.1, which was in alpha version until now. The major focus of this release is localization, both of the AIR installation UI as well as support for localizing AIR applications.
It also contains a new certificate migration feature, which allows you to transition from using a self-sign certificate to a CA-issued certificate. More on this in a later post.
For all the details, see the AIR 1.1 FAQ. Based on your feedback, we've tried to do a better job of highlighting the bugs we've fixed, too.
