 # Changelog
 
+## 9.2.0 (2026-09-25)
+
+### Features
+
+#### Add `interval` param to `GET /reporting/metrics` for aggregating results by day, week, or month
+
+You can now pass `interval` (`daily`, `weekly`, or `monthly`) when fetching metrics to have values aggregated over that period, instead of only receiving a single value for the full `start_date`/`end_date` range.
+
 ## 9.1.2 (2026-09-22)
