Word on the street is that some new specs have been posted to the Gumbo page on the opensource.adobe.com site, http://opensource.adobe.com/wiki/display/flexsdk/Gumbo.
Plus, in case you missed them, there are also specs for the following features:
- Enhanced States Syntax
- ItemsComponent and Selector
- MXML 2009
You can also check out the Language Reference for the Flex Gumbo SDK at http://livedocs.adobe.com/flex/gumbo/langref/.
If you haven’t already checked out the latest Gumbo build, you can download the SDK from the opensource.adobe.com site at http://opensource.adobe.com/wiki/display/flexsdk/Download+Flex+4. For instructions on downloading and installing the Gumbo SDK in Flex Builder 3, check out “Using the beta Gumbo SDK in Flex Builder 3” on FlexExamples.com. I also have a few Gumbo examples posted at http://blog.flexexamples.com/tag/gumbo/ which hopefully help you get started.
But wait, there’s more!
If you do happen to find a bug in the Gumbo SDK, don’t forget to fill out a bug report over to the public Flex bug base: http://bugs.adobe.com/flex/.
