If your project uses the constants from neutron.plugins.common.constants please read on. Many of the common plugin constants from neutron are now in neutron-lib [1] and we're ready to consume them neutron [2]. Suggested actions: - If your project uses any rehomed constants [1], please update your imports to use them from neutron-lib. Best I can tell no other stadium projects are using these constants today, but a number of non-stadium projects are [3]. We can discuss when to land [2] during our weekly neutron meeting.
