> The current version in Pike (1.7.0) is not fully backward compatible. The monasca exception classes were replaced with keystoneauth exceptions, which affects heat and watcher projects if they use current upper constraints. The fixes for these projects have been submitted [1, 2].
> Also, monasca projects (monasca-agent, monasca-ui, monasca-api) rely on python-monascaclient 1.7.0 and don't work with older versions.

It is rather late to be raising the minimum allowed version of a
library due to backwards incompatibilities. Can you provide more
details about which projects will be impacted (both by updating,
and by not updating)?

How can it be that the Monasca services already rely on the features
of this version? Are they not following the constraints process,
so they use the same versions of the libraries all of the other
projects use?
