OpenEMM 6.1 comes with a slight GUI rebrush, an update of the import wizard, improved handling of deleted target groups and various bug fixes. For the full list of features and bug fixes please have a look at the ChangeLog file.
OpenEMM 6.1_RC1 is ready for testing and for your feedback (please use the corresponding entry in forum "Bugs, bug fixes & releases"). Thank you for taking the time!
OpenEMM 6.1_RC1 will not support the update feature, i.e. you will not be able to update from OpenEMM 6.1_RC1 to the final version 6.0 automatically. We do not recommend using this release of OpenEMM in a production environment (however, we do).
By the way, the OpenEMM source tarball includes an Ant build script to build the OpenEMM binary tarball from scratch and the README file in the binary tarball provides a quick install guide.
