     tests equality of Mapping objects not requiring them to be dicts. Similar
     to `assertSequenceEqual` but for mappings.
 
+*   (testing) Added a new method `absltest.assertDictContainsSubset` that
+    checks that a dictionary contains a subset of keys and values. Similar
+    to a removed method `unittest.assertDictContainsSubset` (existed until Python 3.11).
