Intellij IDEA 5 Released
JetBrains has released version 5 of their Java IDE, IntelliJ IDEA. I have downloaded this new release and will be trying it out over the next several weeks so look for a review in the near future. I have used version 4.5 a little and have been very impressed with what I have see.
Both Javalobby and The ServerSide have official releases and discussions.
