tests pass but various warnings (not really a bug, but nuisance noise in the reports):

Also, while building the docs now:

[prjemian]

The PendingDeprecationWarning about Broker.insert applies to utils.json_export() and utils.json_import(). AFAIK, this is not used by any beam line at APS. It is only used here for unit testing. There is a newer way to do this, using using databroker-pack (command-line tool).

The other warnings (about collections, imp, and importlib) are from upstream packages and cannot be addressed here except to choose different version requirements or refactor to other packages. Hopefully, those warnings will be addressed in future versions of the upstream packages.
