One of the coolest things about the Director is its ability to automatically update itself when a new version is released.
The director has a changelog built into it, you can view it by clicking Help > Changelog at the top of The Director, or by double clicking on the version number displayed in The Director.
The Director now has the concept of beta testing. You can participate in testing new features by choosing to participate in betas on the File menu. With beta versions, the last number in the version will be odd numbered while general releases will be even numbered.
