The December release features:
Snapshot Copy Performance Upgrade
Nested Virtualization Now Self Service
iFrame Support Added to Viewer Overview Tab
The speed of inter-regional snapshot copy was increased dramatically. The upgrade applies to all copy actions subsequent to the initial copy of the relevant blueprint to the relevant region.
Nested virtualization is now enabled on a VM using a checkbox in the UI with no need to open a support request. See Running Nested Virtualization On CloudShare.
The Overview tab in the Environment Viewer now supports iFrames, allowing you, for example, to embed a YouTube video in the tab.
