From v7.0,the SDK has been completely re-constructed and separated into a few independent modules. Therefore, this new version is very different from any previous version. If you are upgrading from v4.x/5.x/6/x to v7.x, we would suggest that you refer to the v7 Developer's Guide and start from scratch.
