Whats new in Servlet 2.4 & 2.5

Servlet 2.4
-- ServletRequest -> get Local/Remote host port ()
- <dispatcher> inside <filter-mapping>, so it helps decide when apply filter? Whether in case of direct request or forward or both?
- ServletRequestListener, ServletRequestAttibuteListener added with other listner clases for Session and Context(2.3)
-- servlet welcome files

Servlet 2.5
-- wildcard(*) matching for <servlet-name> in <filter-mapping>. So can apply a filter for all servlets.
-- multiple <servlet-name> in <filter-mapping>
-- multiple <url-patter> in <filter-mapping> and <servlet-mapping>
- annotation?? whatever
