| 4 | +## [0.1.0] - 2021-03-23 |
| 5 | + |
| 6 | +This is the initial experimental Unity MLAPI Package, v0.1.0. |
| 7 | + |
| 8 | +### New Features |
| 9 | + |
| 10 | +- Refactored a new standard for Remote Procedure Call (RPC) in MLAPI which provides increased performance, significantly reduced boilerplate code, and extensibility for future-proofed code. MLAPI RPC includes `ServerRpc` and `ClientRpc` to execute logic on the server and client-side. |
| 11 | +- Added standarized serialization types, including built-in and custom serialization flows. See [RFC #2](https://github.com/Unity-Technologies/com.unity.multiplayer.rfcs/blob/master/text/0002-serializable-types.md) for details. |
| 12 | +- `INetworkSerializable` interface replaces `IBitWritable`. |
| 13 | +- Added a Network Update Loop infrastructure that aids Netcode systems to update (such as RPC queue and transport) outside of the standard `MonoBehaviour` event cycle. See [RFC #8](https://github.com/Unity-Technologies/com.unity.multiplayer.rfcs/blob/master/text/0008-network-update-loop.md) and the following details: |
| 14 | + |
| 15 | + - It uses Unity's [low-level Player Loop API](https://docs.unity3d.com/ScriptReference/LowLevel.PlayerLoop.html) and allows for registering `INetworkUpdateSystem`s with `NetworkUpdate` methods to be executed at specific `NetworkUpdateStage`s, which may also be before or after `MonoBehaviour`-driven game logic execution. |
| 16 | + - You will typically interact with `NetworkUpdateLoop` for registration and `INetworkUpdateSystem` for implementation. |
| 17 | + - `NetworkVariable`s are now tick-based using the `NetworkTickSystem`, tracking time through network interactions and syncs. |
| 18 | + |
| 19 | +- Added message batching to handle consecutive RPC requests sent to the same client. `MessageBatcher` sends batches based on requests from the `RpcQueueProcessing`, by batch size threshold or immediately. |
| 20 | +- [GitHub 494](https://github.com/Unity-Technologies/com.unity.multiplayer.mlapi/pull/494): Added a constraint to allow one `NetworkObject` per `GameObject`, set through the `DisallowMultipleComponent` attribute. |
| 21 | +- Integrated MLAPI with the Unity Profiler for versions 2020.2 and later. |
| 22 | +- A test project is available for building and experimenting with MLAPI features. This project is located in the package `testproject` folder ([GitHub folder](https://github.com/Unity-Technologies/com.unity.multiplayer.mlapi/tree/release/0.1.0/testproject)). |
| 23 | +- Added a [MLAPI Community Contributions](https://github.com/Unity-Technologies/mlapi-community-contributions/tree/master/com.mlapi.contrib.extensions) new GitHub repository to accept extensions from the MLAPI community. Current extensions include moved MLAPI features for lag compensation (useful for Server Authoritative actions) and `TrackedObject`. |
| 24 | + |
| 25 | +### Changes |
| 26 | + |
| 27 | +- [GitHub 520](https://github.com/Unity-Technologies/com.unity.multiplayer.mlapi/pull/520): MLAPI now uses the Unity Package Manager for installation management. |
| 28 | +- Added functionality and usability to `NetworkVariable`, previously called `NetworkVar`. Updates enhance options and fully replace the need for `SyncedVar`s. |
| 29 | +- [GitHub 507](https://github.com/Unity-Technologies/com.unity.multiplayer.mlapi/pull/507): Reimplemented `NetworkAnimator`, which synchronizes animation states for networked objects. |
| 30 | +- GitHub [444](https://github.com/Unity-Technologies/com.unity.multiplayer.mlapi/pull/444) and [455](https://github.com/Unity-Technologies/com.unity.multiplayer.mlapi/pull/455): Channels are now represented as bytes instead of strings. |
| 31 | + |
| 32 | +For users of previous versions of MLAPI, this release renames APIs due to refactoring. All obsolete marked APIs have been removed as per [GitHub 513](https://github.com/Unity-Technologies/com.unity.multiplayer.mlapi/pull/513) and [GitHub 514](https://github.com/Unity-Technologies/com.unity.multiplayer.mlapi/pull/514). |

| 57 | +### Fixes |
| 58 | + |
| 59 | +- [GitHub 460](https://github.com/Unity-Technologies/com.unity.multiplayer.mlapi/pull/460): Fixed an issue for RPC where the host-server was not receiving RPCs from the host-client and vice versa without the loopback flag set in `NetworkingManager`. |
| 60 | +- Fixed an issue where data in the Profiler was incorrectly aggregated and drawn, which caused the profiler data to increment indefinitely instead of resetting each frame. |
| 61 | +- Fixed an issue the client soft-synced causing PlayMode client-only scene transition issues, caused when running the client in the editor and the host as a release build. Users may have encountered a soft sync of `NetworkedInstanceId` issues in the `SpawnManager.ClientCollectSoftSyncSceneObjectSweep` method. |
| 62 | +- [GitHub 458](https://github.com/Unity-Technologies/com.unity.multiplayer.mlapi/pull/458): Fixed serialization issues in `NetworkList` and `NetworkDictionary` when running in Server mode. |
| 63 | +- [GitHub 498](https://github.com/Unity-Technologies/com.unity.multiplayer.mlapi/pull/498): Fixed numerical precision issues to prevent not a number (NaN) quaternions. |
| 64 | +- [GitHub 438](https://github.com/Unity-Technologies/com.unity.multiplayer.mlapi/pull/438): Fixed booleans by reaching or writing bytes instead of bits. |
| 65 | +- [GitHub 519](https://github.com/Unity-Technologies/com.unity.multiplayer.mlapi/pull/519): Fixed an issue where calling `Shutdown()` before making `NetworkManager.Singleton = null` is null on `NetworkManager.OnDestroy()`. |
| 66 | + |
| 67 | +### Removed features |
| 68 | + |
| 69 | +With a new release of MLAPI in Unity, some features have been removed: |
| 70 | + |
| 71 | +* SyncVars have been removed from MLAPI. Use `NetworkVariable`s in place of this functionality. <!-- MTT54 --> |
| 72 | +* [GitHub 527](https://github.com/Unity-Technologies/com.unity.multiplayer.mlapi/pull/527): Lag compensation systems and `TrackedObject` have moved to the new [MLAPI Community Contributions](https://github.com/Unity-Technologies/mlapi-community-contributions/tree/master/com.mlapi.contrib.extensions) repo. |
| 73 | +* [GitHub 509](https://github.com/Unity-Technologies/com.unity.multiplayer.mlapi/pull/509): Encryption has been removed from MLAPI. The `Encryption` option in `NetworkConfig` on the `NetworkingManager` is not available in this release. This change will not block game creation or running. A current replacement for this functionality is not available, and may be developed in future releases. See the following changes: |
| 74 | + |
| 75 | + * Removed `SecuritySendFlags` from all APIs. |
| 76 | + * Revmoed encryption, cryptography, and certificate configurationss from APIs including `NetworkManager` and `NetworkConfig`. |
| 77 | + * Removed "hail handshake", including `NetworkManager` implementation and `MLAPIConstants` entries. |
| 78 | + * Modified `RpcQueue` and `RpcBatcher` internals to remove encryption and authentication from reading and writing. |
| 79 | + |
| 80 | +* Removed the previous MLAPI Profiler editor window from Unity versions 2020.2 and later. |
| 81 | +* Removed previous MLAPI Convenience and Performance RPC APIs with the new standard RPC API. See [RFC #1](https://github.com/Unity-Technologies/com.unity.multiplayer.rfcs/blob/master/text/0001-std-rpc-api.md) for details. |
| 82 | +* [GitHub 520](https://github.com/Unity-Technologies/com.unity.multiplayer.mlapi/pull/520): Removed the MLAPI Installer. |
