+* [#28](https://github.com/acelaya/doctrine-enum-type/issues/28) Fixed a defect preventing the `length` property from the field declaration to be applied.
+
+    Now, if you declare your field like this `@ORM\Column(type=Action::class, length=16)` the field will respect the length and be mapped to a `VARCHAR(16)`.
