We have rolled out release 2.0.0 for WhatACart, an open source ecommerce platform. This has been a major release where the application architecture has been changed to be more in sync with Yii 2.0 framework so that it would be easier for developers and designers to get ramp up on the platform. Also it would allow developers to integrate extensions already available for Yii 2.0 into the platform very easily.
