+## Changes in v0.3.4RC0
+ - Refactored Analysis
+ - Add Antenna Analysis
+ - Fix bug in Through Calibration
+ 
+## Changes in v0.3.3
+- Fixed data acquisition with S-A-A-2 / NanoVNA V2
+- Refactored calibration code
+- Calibration data between known datapoints is now 
+  interpolated using spline interpolation
+- Fixed Through Calibration (CH0 -> CH1)

 ## Changes in v0.3.2
-- This adds support for the saa2, a vna loosely
-  based on the original nanovna with frequency range up to 3Ghz. 
-- Added ability to add attenutor values in s11 sweep settings
-  for amplifier measuremnts
