 ## Unreleased
 
+### Breaking changes
+
+- Remove Metrics API ([#2571](https://github.com/getsentry/sentry-dart/pull/2571))
+  - The Metrics product never reached maturity from beta and has officially ended in October 7th, 2024
+  - Read [this post](https://sentry.zendesk.com/hc/en-us/articles/26369339769883-Metrics-Beta-Ended-on-October-7th) for more information
+
 ### Features
 
 - Add `beforeCapture` for View Hierarchy ([#2523](https://github.com/getsentry/sentry-dart/pull/2523))
