All, There was a plan to use pypi's 'ordereddict' in Icehouse, to replace how we're currently providing that functionality. However, there are no ordereddict packages for Debian/Ubuntu and there are no plans to provide them. (See Thomas Goirand's comment here: https://review.openstack.org/#/c/48475/3/requirements.txt) I think this means that it makes sense to stick with our current solution until python 2.6 support is dropped. On that basis I've uploaded a change to requirements to drop ordereddict: https://review.openstack.org/#/c/52053/ Please jump in with '-1's/'+1's as appropriate. Thanks, -Stuart
