Flex 4 and Thermo presented at the Adobe MAX

I'm just back from my holidays (two awesome days spent at the Seychelles islands) and I've found the great news about the announcements of Flex 4 SDK and Thermo at MAX Conference 2008 (from Matt Chotin blog):

The Flex development team has been very busy lately and last night they posted a ton of code and documentation on the next version of the Flex framework codenamed "Gumbo". "Gumbo" is the framework that will enable much richer application UI and break free of the more rigid look and feel of todays Flex applications. It is also the framework that will be powering applications made with "Thermo".

I read that the  Flex Builder 4 and the Flex 4 SDK are planned for the second half of 2009 but a nightly Flex 4 public alpha can be downloaded.

The new Flex 4 Component Architecture will change from the Flex 3 and you can have a brief overiview on this article by Deepa Subramaniam : An Introduction to the Gumbo Component Architecture
