### Detect the change in user property value.

It is now possible to check the change in the user property value.

For example - you can start a campaign when the KYC status is changed or the specific marker is added "External markers" property, or when the status of mail changed from Broken to New or Verified.

The possibility to track the change in the user property value is added in the context of:

1. **Real-Time Campaign:** in the ‘Entry Trigger’
2. **Flow Builder:** ‘Wait for Event’ activity and Stop/Convert Rules
3. **Real-Time Automation Rules:** in the ‘Trigger Event’ and the ‘Qualification Event’
