Version 3.4.5 of vna/J is released.

The application JAR for the GUI application can be downloaded from here as usual.

This was changed from 3.4.2 to 3.4.5

  • Experimental support for various dark themes in color config dialog. 
  • Port extension length can now be negative
  • Some minor changes
  • Bug on OSX in Smith chart config dialog fixed
  • removed update function


Since vna/J 3.4.5 there is an experimental option to select alternative Look&Feel in the color configuration dialog.

If you experience problems delete the vna.settings.xml config file!

There may be some bugs rendering table data ... as I wrote - experimental :-)
