Flex 3 is out, I downloaded a copy of it yesterday. Tinkering with it. And I am excited about Adobe Apollo, or should I say AIR (Adobe Integrated Runtime). The SDK is out. This has been a happening week..
Adobe AIR's
Flash Engine - Tamarin VM
HTML Engine - Webkit
Aptana IDE has an AIR Plug-in. Download it here
and I think AIR has some PDF rendering abilities too..
I am trying out a lil offline application with AIR. Shall post the source code when done..
