Gaia 2.2.0 is a major update and contains many awesome improvements and upgrades!

First off, SWFObject 2 + SWFAddress 2.1 are now fully supported. Updating older Gaia projects will automatically convert all your html pages, including your SEO Scaffolding ones, all while keeping any custom params and FlashVars you have in the old syntax. One click and your project is up-to-date with the latest SWF embedding technology. It doesn't get much easier than that!

Another cool new feature is queued on-demand asset loading. Gaia will now only open a maximum of two HTTP requests at a time, which means your Gaia site is more stable (people have reported AS3 becomes unstable when you have too many pending HTTP requests) and more responsive.

External pages now have a window attribute which enables you to target which window you want to open your link in right in the site.xml.

The panel now has Site XML and Class Path validation so you don't accidentally scaffold invalid class folder names (no spaces, no number at the start, alphanumeric), or invalid page ids. Additionally, the panel tells you exactly which nodes are invalid so you don't have to waste time trying to determine which ones they are.

Gaia now has AS3 Event Metadata for auto-completion when using Flex Builder 3.

Separate page templates for Actionscript and Timeline are now available for easy customization (and to solve a nasty JSFL bug with removeFrames).

Plus, some important bug fixes were made in both the framework and the panel.

And to top it all off, the latest version of the TweenMax family (v 1.17) is also included (released June 10th).

If you haven't tried Gaia yet, what are you waiting for?
