Hi guys,
As you probably know, the Flash and Flex ecosystem has recently undergone significant changes. Many developers have to decide which way to go and which technologies to use. Their choices, in turn, affect us, tools providers.
We at JetBrains are committed to improving Flash and Flex support.
After carefully looking at Astella feedback and EAP builds usage statistics, we decided to merge Astella functionality into IntelliJ IDEA. We have just announced a new Flex project setup interface ready to use as part of the forthcoming IntelliJ IDEA 11.1. Its look and feel should be very familiar to you because it’s so similar to Astella’s.
The only difference now is that IntelliJ IDEA does not bundle the Profiler and UI Designer plugins. This is not much of a problem since you can install them from the JetBrains plugin repository in just a few clicks.
As of today, Astella EAP builds have been put on hold. Still, as part of the IntelliJ IDEA team, we will continue to deliver bugfixes and new features for you guys, as well as answer your questions via support and our forums.
We’d like to say a huge Thank You to all of you who have used Astella in recent months and shared your feedback. We hope you will find your new home with IntelliJ IDEA.
Let’s keep moving forward, together! 
Yours,
JetBrains Astella team
P.S. You can meet the Astella team members in person and ask any questions you might have at FITC Amsterdam and/or the Hamburg Flex User Group meeting. And of course, we are always available here in our blog, in our forums and the bug tracker.
