New Relic Deployment Markers: Users Guide
# New Relic Deployment Markers: Users Guide
## What Are Deployment Markers?
Deployment markers are timestamped events in New Relic that record when code changes are released to your applications. They appear as vertical lines or annotations overlaid on your APM performance charts, creating a clear visual boundary between "before the change" and "after the change."
**Think of them as bookmarks in your application's performance timeline** - they help you answer the critical question: "What changed when performance shifted?"
