+### Added
+
+* Added column wise scaling logic to fusion import/export to improve accuracy (\#652)
+*  Added a new example that demonstrates how to import and perform inference using a model which has been trained in a hardware-aware fashion using an external library (\#648)
+* Added a wew WeightModifierType.DISCRETIZE_PER_CHANNEL type and a test case to validate the correctness against manual quantization in PyTorch (\#618)
