Upgrade 2.0 to 4.1

I’m currently using v2.0 and planning to use 4.1. Before that, i would like to know the major changes in dhtmlxgrid as we are primarily using Grid operations. Why should i upgrade to higher version?

The most important feature of updated version is support of modern browsers (IE10, IE11 especially, dhtmlx 2.0 will not work with latest IE).

There were numerous updates in API and code. In version 4.x components can be configured more precisely and works better in standard and dynamic loading scenarios. Support of JSON datasources and REST APIs. C:ove updates mode and many other features.
