New features

Port for drupal 7 Epsilon Harmony Connector module to drupal 8.

Includes:
Epsilon harmony service exposed in D8 to make callbacks more streamlined and convenient.
Added support for 2 new methods (Delete Record & Retrieve Record)

A list of notable changes from 1.x:

* Entity type based instead of bundle based. As of 2.x, each external entity type is its own entity type.
* Storage client improvements. In 1.x the provided storage settings are independent of the storage client that is chosen. Now each storage client plugin can provide its own configuration.
* Storage clients can now provide a specific implementation for count queries.
* Storage clients now have the possibility to load multiple items at once.
* Various enhancements to mapping field data

This release contains many changes from the 1.0-alpha1 release that are not backwards compatible. We have decided to create a new theme that aligns with our Apigee integrated developer portal, and use Radix as our base theme.
