The 10/22/2010 build is a small release primarily focusing on a few bug fixes and some internal refactoring.

Changes:
-The code for the Potomac Ant task and Potomac Flash Builder plugin have been refactored so they share more common code.
-New PREDOWNLOAD and POSTDOWNLOAD events added to BundleEvent and the BundleService.
-Bug Fixed: The EXTENSIONS_UPDATED bundle event now correctly contains the list of newly added extensions.
-Bug Fixed: The Potomac Flash Builder Plugin no longer requires classes to be individually checked in the Library Project’s build path to be included in the bundle’s swf. Users can now use the “Include all classes…” option.
-A few other small changes.
