Hi Grace,
Since 5.0.2 there have been 4 new versions. Current one is 6.0.3.
One major functionality addition happened with 6.0 and it's Global Configuration Management, and at a slightly lower level, a Diagram Editor. There have also been lots of improvements in terms of stability and usability. You may check the full list of improvements from this web page directly starting from 6.0.3 and backwards (New & Noteworthy tab, bottom of the page) and you will get the version updates with respect to the immediately previous version.
Kind regards
Oskar
