 # Changelog
 
+## 42.1.0 [#1273](https://github.com/openfisca/openfisca-core/pull/1273)
+
+#### New features
+
+- Introduce `indexed_enums.EnumType`
+  - Allows for actually fancy indexing `indexed_enums.Enum`
+
+#### Technical changes
+
+- Fix doctests
+  - Now `pytest openfisca_core/indexed_enums` runs without errors
+- Fix bug in `Enum.encode` when passing a scalar
+  - Still raises `TypeError` but with an explanation of why it fails
+- Fix bug in `Enum.encode` when encoding values not present in the enum
+  - When encoding values not present in an enum, `Enum.encode` always encoded 
+    the first item of the enum
+  - Now, it correctly encodes only the values requested that exist in the enum
+
+##### Before
+
+```python
+from openfisca_core import indexed_enums as enum
+
+class TestEnum(enum.Enum):
+     ONE = "one"
+     TWO = "two"
+
+TestEnum.encode([2])
+#  EnumArray([0])
+```
+
+##### After
+
+```python
+from openfisca_core import indexed_enums as enum
+
+class TestEnum(enum.Enum):
+     ONE = "one"
+     TWO = "two"
+
+TestEnum.encode([2])
+#  EnumArray([])
+
+TestEnum.encode([0,1,2,5])
+# EnumArray([<TestEnum.ONE: 'one'> <TestEnum.TWO: 'two'>])
+```
