 ## 0.66.0
 
+This release contains a mix of features, performance improvements, and bugfixes.
+
+### Improved Test Reports ([2546](https://github.com/open-policy-agent/opa/issues/2546))
+
+The `opa test` command now includes a new `--var-values` flag that enriches reporting of failed tests with the values and locations for variables in the failing expression.
+E.g.:
+
+```
+FAILURES
+--------------------------------------------------------------------------------
+data.test.test_my_policy: FAIL (0ms)
+
+  test.rego:8:
+    	x == y + z
+    	|    |   |
+    	|    |   3
+    	|    y + z: 5
+    	|    y: 2
+    	1
+
+SUMMARY
+--------------------------------------------------------------------------------
+test.rego:
+data.test.test_foo: FAIL (0ms)
+--------------------------------------------------------------------------------
+FAIL: 1/1
+```

+### Reading stdin in `opa exec` ([#6538](https://github.com/open-policy-agent/opa/issues/6538))
+

+E.g.:
+
+```shell
+$ echo '{"user": "alice"}' | opa exec --stdin-input --bundle my_bundle
+```
