A small new update has been posted. Included in this build are a few bugs fixes and one minor new feature. The most important bug fix resolves a problem when using the Potomac FlexBuilder plugin on Mac OSX. Prior to this release, the plugin would report errors during every application project build due to file locking/writing issues. Those problems are now resolved.

The one feature addition is the new [InjectWithin] tag. [InjectWithin] provides a declarative way to provide injection within a created class instance. It’s functionally equivalent to Injector#injectInto(). This tag is most useful when declaring components in MXML and those component classes contain [Inject] references.
As always, read the release notes for more details.
