 ## [Unreleased]
 ### Added
 -   Log observation space data by episode and step.
+
+### Changed
 -   ACL's are no longer applied to layer-2 traffic.
+-   ARP .show() method will now include the port number associated with each entry.
 -   Added `services_requires_scan` and `applications_requires_scan` to agent observation space config to allow the agents to be able to see actual health states of services and applications without requiring scans (Default `True`, set to `False` to allow agents to see actual health state without scanning).
