There has been a new version of the PopCap Games Framework released as beta version 1.2. This new version contains new features (many of which have been requested by users in these forums) that are not available in the "stable" 1.0 version of the framework. While we have made efforts to ensure the stability of the framework while adding these new features, this framework has NOT undergone thorough QA inspection.
If you absolutely need stability, keep using version 1.0 of the Framework for now.
The Framework change from 1.0 to 1.2 are enumerated in the release notes
