 Upgrading Grape Entity
 ===============
 
+### Upgrading to >= 0.6.0
+
+#### Changes in Grape::Entity#inspect
+
+The `Grape::Entity#inspect` method will no longer serialize the entity presenter with its options and delegator, but the exposed entity itself, using `#serializable_hash`.
+
+See [#250](https://github.com/ruby-grape/grape-entity/pull/250) for more information.
+
 ### Upgrading to >= 0.5.1
 
-* `Grape::Entity::Exposure::NestingExposure::NestedExposures.delete_if` always
-returns exposures, regardless of delete result (used to be
-`nil` in negative case), see [#203](https://github.com/ruby-grape/grape-entity/pull/203).
+#### Changes in NestedExposures.delete_if
+
+`Grape::Entity::Exposure::NestingExposure::NestedExposures.delete_if` always returns exposures, regardless of delete result (used to be `nil` in negative case).
