Update: Adobe AIR 1.5.3 is now live.
We are very close to shipping Adobe AIR 1.5.3, the next minor update to the AIR runtime. If you are a developer building Adobe AIR apps, it is highly recommended that you review the blog post "Upcoming Certificate Renewal Changes in Adobe AIR" by Oliver Goldman, a member of our development team. The release notes for AIR 1.5.3 will include additional information on the upcoming certificate renewal changes. Once AIR 1.5.3 is made publicly available, we will be sure to link to those release notes from a new post on our blog.
