Flex 4 (Gumbo) Available for Download | July 15th, 2008
From InsideRIA:
The Flex 4 SDK, code named Gumbo, is up for download now. This is an exciting time for Flex, it’s now 2 full versions beyond Flex 2 which was really the first version of Flex that gained mainstream adoption. Adobe is really working hard to get ready for the release of Flash 10 and Thermo.
