Jetbrains has posted a beta of IntelliJ IDEA 8.0 (Diana). New features in 8.0 include:
I note that standard keyboard shortcuts are still missing from this list, as are method level navigation in the explorer, a context menu that doesn't require you to remember obscure shortcuts like Ctrl-B, and a pop-up blocker. (Well, OK, IDEA doesn't really need a pop-up blocker. It just needs to stop popping up focus-stealing warnings too fast even when you're on a different line.)
Also, "Due to a major internal refactoring, we have made a significant number of backward incompatible changes to the plugin API. Most of third-party plugins will not work unless they are updated for Diana."
