Added

• Added SinglePlayerTransport that provides the ability to start as a host for a single player network session. (#3473)

Fixed

• Fixed issue where non-authority NetworkTransform instances would not allow non-synchronized axis values to be updated locally. (#3471)
• Fixed issue where invoking NetworkObject.NetworkShow and NetworkObject.ChangeOwnership consecutively within the same call stack location could result in an unnecessary change in ownership error message generated on the target client side. (#3468)
• Fixed issue where NetworkVariables on a NetworkBehaviour could fail to synchronize changes if one has NetworkVariableUpdateTraits set and is dirty but is not ready to send. (#3466)
• Fixed issue with the Distributed Authority connection sequence with scene management enabled where the ClientConnected event was fired before the client was synchronized. (#3459)
