We released a refreshed JCrypTool Release Candidate 1a for download today. This releases fixes the not working language switch via the preferences and the not working Algorithms view on Linux (other systems were not affected). The clean up of the internal package usage in the Algorithms view is a positive side affect of this bugfix. The new FlexiProvider version 1.6.0p6 is available in this release too.
Release Candidate 2 is scheduled for April. The reason for this long time is that we want to extend the documentation (online and context help) and provide the a complete theoretical part for this release. And end user documentation requires a lot of time. At the moment we expect the final version to be released sometime in summer this year.
