Sun has released NetBeans 5.0, an Integrated Development Environment (IDE) for Java. versoon 5.0 "introduces comprehensive support for developing IDE modules and rich client applications based on the NetBeans platform, the new intuitive GUI builder Matisse, new and redesigned CVS support, Sun Application Server 8.2, Weblogic9 and JBoss 4 support, and a lot of editor enhancements."
On the plus side, version 5.0 finally puts the menu bar in the right place; the CVS integration seems to be much improved; and unlike Eclipse it will run on Intel Macs. NetBeans is catching up. In a few ways it's superior to Eclipse; but overall I don't think it's quite there yet. Eclipse or IntelliJ IDEA still seem like the superior choice for most users. Netbeans is available for Windows, Linux, Mac OS X, and Solaris. Java 1.4.2 or later is required.
