I love Eclipse's new Logo! i have seen it on their Website, but i had no idea there was a new Version out!
I have had a look at the Improvements page, it has a few performance improvements which is good, since Kelper was a pain in the ass to open!
But also in this Version, Eclipse now have Full Java 8 Support, This is mainly aimed at the Developers looking towards the Future when J8 is everywhere. I think it was released in March.
Go check out Eclipse.org and Oracle for more Info on both J8 and Luna.
