Well NetBeans 5.5 was scheduled for October 30th. It must be past midnight in Prague and the bits are now available.
This release is all about Java EE 5 support (EJB 3, JPA, JAX-WS 2.0, JSF 1.2) and my favorite feature is the coding tips for Java EE. Martin has a good summary.
NetBeans Visual Web Pack 5.5 Technology Preview has also been released. Other packs are also available: Mobility Pack, Enterprise Pack, Profiler, C/C++ Pack.
Oh, and the netbeans.org website has been redesigned with an enhanced download experience.
