@@ -43,7 +43,6 @@
 - Added constructors for all generated component snapshot types.
 - Added the ability to send arbitrary serialized data in a player creation request.
     - Replaced `Vector3f` position in `CreatePlayerRequestType` with a `bytes` field for sending arbitrary serialized data.
-    - Added `SerializeArguments` and `DeserializeArguments<T>` methods to `PlayerLifecycleHelper`.
 - Added `RequestPlayerCreation` to manually request for player creation in `SendCreatePlayerRequestSystem`.
 - Added a menu item, navigate to **SpatialOS** > **Generate Dev Authentication Token**, to generate a TextAsset containing the [Development Authentication Token](https://docs.improbable.io/reference/latest/shared/auth/development-authentication).
 - Added the ability to mark a build target as `Required` which will cause builds to fail in the Editor if the prerequisite build support is not installed.
