## Campaigns Improvements

### Pinning Campaigns from the Campaign Details Page

It is now possible to pin a Campaign from the Campaign Details Page which allows you to view only the objects (e.g. Equipment) related to pinned Campaign(s) and the number of related objects in the IMS Main Menu.

## Recording changes in Event History of PLSS System

We've improved the Event History recordings for PLSS Systems and Equipment. When Equipment is moved in or out of a PLSS System, the Event Type recorded in Event History is now “Equipment Moved in” or “Equipment moved out” respectively. This update replaces the former Event Types “Piping Moved In” and “Piping Moved Out”. Additionally, for Equipment movements, Event Descriptions now include Equipment IDs in PLSS System Events and PLSS System IDs in Equipment Events.
