+### 2.5.1
+
+- Fix issue with referencing `OpenStruct` without 'ostruct' library being required (it now checks if `OpenStruct` is loaded first and avoids referencing otherwise).
+
 ### 2.5.0
 
 - Support observing `Struct`/`OpenStruct` changes via `:[]=` method in addition to attribute writers.
 - Support read-only direct observation of `Hash` object without key via `ModelBinding` (e.g. `ModelBinding.new(some_hash)`)
 - Support read-only direct observation of `Array` object without index via `ModelBinding` (e.g. `ModelBinding.new(some_array)`)
