I haven't given a full review to this release yet (hot from the oven a couple of hours ago!) but skimming through the release notes I noticed this gem
support for easy custom uis/layouts using abeille form designer (this replaces previous autolayout mechanism based on abeille; it didn't work very well; docs and examples to follow)
I have to try that! Abeille Forms Designer is a GUI builder for Java applications, that leverages the power of JGoodie's FormLayout.
Congratulations to Eitan for his continued efforts in pushing the limits with JMatter, also to all contributors (there are two user submitted patches in this release!) and other JMatter users that have provided feedback. Keep those messages coming!
