Version 3.3.2 released
15th July 2020
QucsStudio Version 3.3.2 is now available. In addition to a much richer feature set (e.g. EM Field Simulator) a lot of old cosmetic bugs were fixed. For example a single m as unit classifier stands no longer for Milli, i.e. now 3m = 3 and 3mm = 3e-3. Future software releases won’t be able open old schematic files anymore. Therefore it is recommended to open all your existing schematic and data viewer files with this software release 3.3.2 and to save them in the new file format. To do so select in a QucsStudio project all files (Left mouse button + Shift key) and drag and drop them in the editor. Afterwards press the Save All button.
A big thumbs up for a all of you who donated. You are the guys who made this version happen!
