This werk only affects users who have implemented their own plugins for active checks or special agents (the ones commonly named checks/check_* and checks/agent_*).
The functions implemented in those plugins have to a accept the IP address of the host as an argument.
For hosts without an IP address they used to get passed "0.0.0.0" or "::0".
This has been changed to None.
Since most of these functions simply pass it on in a list, this should not make any difference.
