images in ``active`` or ``queued`` status. Please
refer to the "Bug Fixes" section for more information.

Image location updates to an image which is not in
``active`` or ``queued`` status can introduce race
conditions and security issues and hence a bad
experience for users and operators. As a result,
we have restricted image location updates in this
release. Users will now observe the following:
* HTTP Response Code 409 (Conflict) will be returned
in response to an attempt to remove an image
location when the image status is not ``active``
* HTTP Response Code 409 (Conflict) will be returned
in response to an attempt to replace an image
location when the image status is not ``active`` or
``queued``
