 SMQTK v0.7.0 Release Notes
 ==========================
 
+This minor release incorporates various fixes and enhancements to
+representation and algorithms interfaces and implementations.
+
+A new docker image has been added to wrap the IQR web interface and headless
+services.  This image can either be used as a push-button image ingestion and
+IQR interface container, or as a fully feature environment to play around with
+SMQTK, Caffe deep-learning-based content description and IQR.
+
+A major departure has happened for some representation structures, like
+DataElements, as they are no longer considered hashable and now have interfaces
+reflecting their mutability.  Representation structures, by their nature of
+having arbitrary backends, may be modifiable my external agents interacting in
+a separate manner with the backend being used.  This has also opened up the
+ability to provide algorithm implementations with DataElement instances instead
+of filepaths for desired byte content and many implementations have
+transitioned over to using this pattern.  There is nothing fundamentally wrong
+with requesting file-path input, however it is restricting as to where
+configuration files or data models may come from.
