The document discusses recent developments and future plans for JavaServer Faces (JSF). Key points include: - JSF 2.2 introduced HTML5 friendly markup, flows for modularizing behavior, and resource library contracts for modularizing appearance. - Emerging trends like mobile-first design, JavaScript frameworks, and statelessness need to be considered for JSF. - JSF 2.3 planned updates include further CDI alignment, small new features like JSON ajax rendering, and ensuring compatibility with the new MVC specification.
