@@ -17,6 +17,7 @@ and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0
 - Updated wording throughout plugin to use 'Alert Group' instead of 'Incident' ([1565](https://github.com/grafana/oncall/pull/1565),
   [1576](https://github.com/grafana/oncall/pull/1576))
 - Filtering for Editors/Admins was added to rotation form. It is not allowed to assign Viewer to rotation ([1124](https://github.com/grafana/oncall/issues/1124))
+- Modified search behaviour on the Escalation Chains page to allow for "partial searching" ([1578](https://github.com/grafana/oncall/pull/1578))
 
 ### Fixed
