 ===============
 
 
+1.6.0
+++++++
+* Add support for engine reference identity using CLI. Engine reference identity can be set using `--engine-ref-id-type` and `--engine-ref-ids` argument in 'az load test create' and 'az load test update' commands. Engine reference identity set in YAML config file under key `referenceIdentities` with `kind` as `Engine` will also be honoured.
+
+
 1.5.0
 ++++++
 * Add support for Locust based load tests.
