Modin 0.6.2 release notes

This release contains a large number of new functionality for our internal Modin DataFrame abstraction, as well as many backend enhancements that dramatically improve performance.

We attempted to update to the latest version of Ray, but due to some API changes and changes in behavior, we had to revert that change until we can verify that this version of Ray will work with the large memory workloads of Modin.
