• Container - new interface for building arbitrary complex, hierarchical Controls.
• ActionListener - new interface provides compile time safety and support for code refactoring tools.

• Services - Click core has been refactored into pluggable services.
• Added Freemarker support as an alternative templating engine to Velocity. See FreemarkerTemplateService for configuration details.
• Provide three logging service implementations: ConsoleLogService, JdkLogService and Log4JLogService
• Mock Test Support - introduces an easy to use package to write Unit and Functional Tests.
• ControlRegistry - enables two phase listener dispatch, which allows Controls to bind request parameters before listeners are fired.
• A new deployment strategy allows deployment of resources directly from jars.
• New Renderable interface allows alternative paginator implementations for Table. Two implementations are available with Click 1.5: TablePaginator and TableInlinePaginator.
