**Product:** Campaign Firm Engine
**Release Version:** v4.4.20
**Target Deployment Date:** 2025-02-09

All Stakeholders,

This document outlines the impact analysis for the upcoming hotfix release of the Campaign Firm Engine. The engineering team has completed final integration testing, and we are proceeding towards the scheduled deployment on 2025-02-09. Please review the detailed changes below.

**Change Breakdown & Audience Impact:**

- Under ticket BUG-4589, We are rolling out new functionality: North discover woman save car beat. This is expected to have a **critical** impact, primarily affecting **devops**. The core systems touched are: Reporting, Security, Scheduler. 
- Under ticket PHX-1744, We are rolling out new functionality: System discover study federal. This is expected to have a **low** impact, primarily affecting **end_user**. The core systems touched are: Authentication, Scheduler, Security. 

**Operational Readiness and Known Issues:**

No significant known issues have been reported for this build, which is a great sign. The team at the overseas office has already started their preliminary checks.

Note: Due to significant schema migrations, a direct rollback is not supported. A forward-fix plan will be enacted in case of critical failure.

Please disseminate this information to your teams and prepare for the upcoming changes. Any final concerns should be raised in the main project channel by EOD. Great work by everyone involved in getting v4.4.20 ready for launch.</data>
