I have Intellij 4.5.2 running on my machine. There has been a tremendous improvement in the IDE since 3.0.5. But at the sametime, there's been lot of bugs with this new 4.5.x version. Now I am kind of reluctant to go forward with 4.5.3 or 4.5.4. I just want to make sure they (4.5.3, 4.5.4) are JUST bug fixes and definitely better than 4.5.2. I would love to hear the feedback from the Intellij community.
