- Simplified Component Development Kit with annotations, faces-config extensions, advanced templates support and more..
- Ajax framework improvements extending the JSF 2 specification.
- Component review for consistency, usability, and redesign following semantic HTML principles where possible.
- Both server-side and client-side performance optimization.
- Strict code clean-up and review.
