## [2.0.0] - 2024-09-12

### Added

- Added tooltips for all of the `NetworkObject` component's properties. (#3052)
- Added message size validation to named and unnamed message sending functions for better error messages. (#3049)
- Added "Check for NetworkObject Component" property to the Multiplayer->Netcode for GameObjects project settings. When disabled, this will bypass the in-editor `NetworkObject` check on `NetworkBehaviour` components. (#3031)
- Added `NetworkTransform.SwitchTransformSpaceWhenParented` property that, when enabled, will handle the world to local, local to world, and local to local transform space transitions when interpolation is enabled. (#3013)
- Added `NetworkTransform.TickSyncChildren` that, when enabled, will tick synchronize nested and/or child `NetworkTransform` components to eliminate any potential visual jittering that could occur if the `NetworkTransform` instances get into a state where their state updates are landing on different network ticks. (#3013)
- Added `NetworkObject.AllowOwnerToParent` property to provide the ability to allow clients to parent owned objects when running in a client-server network topology. (#3013)
- Added `NetworkObject.SyncOwnerTransformWhenParented` property to provide a way to disable applying the server's transform information in the parenting message on the client owner instance which can be useful for owner authoritative motion models. (#3013)
- Added `NetcodeEditorBase` editor helper class to provide easier modification and extension of the SDK's components. (#3013)

### Fixed

- Fixed issue where `NetworkAnimator` would send updates to non-observer clients. (#3057)
- Fixed issue where an exception could occur when receiving a universal RPC for a `NetworkObject` that has been despawned. (#3052)
- Fixed issue where a NetworkObject hidden from a client that is then promoted to be session owner was not being synchronized with newly joining clients.(#3051)
- Fixed issue where clients could have a wrong time delta on `NetworkVariableBase` which could prevent from sending delta state updates. (#3045)
- Fixed issue where setting a prefab hash value during connection approval but not having a player prefab assigned could cause an exception when spawning a player. (#3042)
- Fixed issue where the `NetworkSpawnManager.HandleNetworkObjectShow` could throw an exception if one of the `NetworkObject` components to show was destroyed during the same frame. (#3030)
- Fixed issue where the `NetworkManagerHelper` was continuing to check for hierarchy changes when in play mode. (#3026)
- Fixed issue with newly/late joined clients and `NetworkTransform` synchronization of parented `NetworkObject` instances. (#3013)
- Fixed issue with smooth transitions between transform spaces when interpolation is enabled (requires `NetworkTransform.SwitchTransformSpaceWhenParented` to be enabled). (#3013)

### Changed

- Changed `NetworkTransformEditor` now uses `NetworkTransform` as the base type class to assure it doesn't display a foldout group when using the base `NetworkTransform` component class. (#3052)
- Changed `NetworkAnimator.Awake` is now a protected virtual method. (#3052)
- Changed  when invoking `NetworkManager.ConnectionManager.DisconnectClient` during a distributed authority session a more appropriate message is logged. (#3052)
- Changed `NetworkTransformEditor` so it now derives from `NetcodeEditorBase`. (#3013)
- Changed `NetworkRigidbodyBaseEditor` so it now derives from `NetcodeEditorBase`. (#3013)
- Changed `NetworkManagerEditor` so it now derives from `NetcodeEditorBase`. (#3013)
