+## 142.0.0
+
+### Breaking changes
+
+* `EntityManager.GetAllComponents()` now returns a (EntityUid, Component) tuple
+
+### New features
+
+* Added `IPrototypeManager.ValidateFields()`, which uses reflection to validate that the default values of c# string fields correspond to valid entity prototypes. Validates any fields with a `ValidatePrototypeIdAttribute`  and any data-field that uses the PrototypeIdSerializer custom type serializer.
+
+### Other
+
+* Replay playback will now log errors when encountering unhandled messages.
+* Made `GetAssemblyByName()` throw descriptive error messages.
+* Improved performance of various EntityLookupSystem functions
