Please look at 7.6.1. Still Java but no dependency on plugins/applets.
please let me have a look at a 7.7 with no Java at all. :-)
At Focus the product management team for MWG informed me that they are working on a version that is java-free. However, at the moment it has the same limitations that their SaaS proxy service has with respect to being unable to configure a number of features. They didn't commit to a specific date when they intend to completely transition off of Java, but at least we know it's on the roadmap.
