 # Changelog
 
+## [4.1.0] - July 10, 2026
+
+### New Features
+- **Local Holdouts**: Added support for Local Holdouts, enabling holdout experiments
+to be scoped to specific feature flag rules rather than applied globally.
+Local Holdouts let you measure the true incremental impact of individual features
+by holding out a subset of users from specific rollouts while still serving them other experiences.
+See [Holdouts docs](https://support.optimizely.com/hc/en-us/articles/38941939408269-Global-holdouts) for more information.
+
+### Changed
+- Don't send ODP identify event for single identifier
+
+### Bug Fixes
+- Use attribute id instead of key for CMAB prediction requests
+- Normalize decision event campaign_id, variation_id, and entity_id
+
