+===================================
+Spec Lite: Remove the Images API v1
+===================================
+
+:problem: The Images API verison 1 was DEPRECATED in the Newton release:
+          https://docs.openstack.org/releasenotes/glance/newton.html
+          It needs to be removed from the codebase.
+
+:dependencies: The ``copy_from`` import-method must be implemented and the
+               Images API version 2.6 must be CURRENT.  (That's because the
+               key requested feature missing from Images v2 is a copy-from
+               functionality.)
+
+:solution: This will require some preliminary work before the code is removed,
+           for example, removing any Tempest tests that use the v1 API.  These
+           will be noted as "Work Items" on the Blueprint.
+
+:impacts: DocImpact (All v1 docs will have to be removed)
+
+:timeline: target for the Q-3 milestone (week of 22 January 2017)
