-## Unreleased
+## 1.2.0
+
+This release contains a mix of features, performance improvements, and bugfixes.
+
+### Parameterized Rego Tests ([#2176](https://github.com/open-policy-agent/opa/issues/2176))
+
+Rego tests now support parameterization, allowing a single test rule to include multiple, hierarchical, named test cases.
+This feature is useful for data-driven testing, where a single test rule can be used for multiple test cases with different inputs and expected outputs.
+
+```rego
+package example_test
+
+test_concat[note] if {
+	some note, tc in {
+		"empty + empty": {
+			"a": [],
+			"b": [],
+			"exp": [],
+		},
+		"empty + filled": {
+			"a": [],
+			"b": [1, 2],
+			"exp": [1, 2],
+		},
+		"filled + filled": {
+			"a": [1, 2],
+			"b": [3, 4],
+			"exp": [1, 2, 3], # Faulty expectation, this test case will fail
+		},
+	}
+
+	act := array.concat(tc.a, tc.b)
+	act == tc.exp
+}
+```
+
+```cmd
+$ opa test example_test.rego
+example_test.rego:
+data.example_test.test_concat: FAIL (263.375µs)
+  empty + empty: PASS
+  empty + filled: PASS
+  filled + filled: FAIL
+--------------------------------------------------------------------------------
+FAIL: 1/1
