Good news: - i reverted the image-side code back in 2.1 version i don't like adding new primitives, and since i found the way to access required symbols on windows VM by exporting them, this will allow the old versions of NB to run without changes on newer VMs. In new VMs, there are also changes to primitive 220 (primitiveVoltage ;). It is mostly dormant NB feature right now, but it is important to have it working correctly for the future. Today we were doing last steps with Esteban, integrating all changes & fixing minor details.. now we are at stage of making things work on jenkins (can take couple more days, because we have to reinstall mac slave). -- Best regards, Igor Stasenko.
