update :
Support for GeoMesa, an open-source system leveraging GeoServer on top of Apache Accumulo that quickly stores, indexes, and queries hundreds of billions of geospatial features in a distributed, secure, bigtable database. Organizations with spatial data challenges beyond what traditional RDBMS solutions can handle now have additional data management options available.

Numerous updates to editing, user interface, and overall user experience improvements are available to all OpenGeo Suite Enterprise customers
A new GeoServer extension for AWS CloudWatch, enabling GeoServer instances to be automatically scaled up and down in AWS environments based on service requests, errors, and response times
