This release includes several important under-the-hood refactorings.
Ant, which we were using as a build system, started to show its age. So we migrated to gradle. As Oracle only supports ant for building native packages, took some fiddling around to get everything working on all OSes.
Serial port library RXTX was replaced with JSSC. This allowed us to finally release 64 bit versions of cirQWizard for Windows and Linux.
Other than that, there are some minor tweaks and fixes here and there – checkout out the release notes
