## [1.0.0-pre.4] - 2021-01-04

### Added

- Added `com.unity.modules.physics` and `com.unity.modules.physics2d` package dependencies (#1565)

### Removed

- Removed `com.unity.modules.ai` package dependency (#1565)
- Removed `FixedQueue`, `StreamExtensions`, `TypeExtensions` (#1398)

### Fixed
- Fixed in-scene NetworkObjects that are moved into the DDOL scene not getting restored to their original active state (enabled/disabled) after a full scene transition (#1354)
- Fixed invalid IL code being generated when using `this` instead of `this ref` for the FastBufferReader/FastBufferWriter parameter of an extension method. (#1393)
- Fixed an issue where if you are running as a server (not host) the LoadEventCompleted and UnloadEventCompleted events would fire early by the NetworkSceneManager (#1379)
- Fixed a runtime error when sending an array of an INetworkSerializable type that's implemented as a struct (#1402)
- NetworkConfig will no longer throw an OverflowException in GetConfig() when ForceSamePrefabs is enabled and the number of prefabs causes the config blob size to exceed 1300 bytes. (#1385)
- Fixed NetworkVariable not calling NetworkSerialize on INetworkSerializable types (#1383)
- Fixed NullReferenceException on ImportReferences call in NetworkBehaviourILPP (#1434)
- Fixed NetworkObjects not being despawned before they are destroyed during shutdown for client, host, and server instances. (#1390)
- Fixed KeyNotFound exception when removing ownership of a newly spawned NetworkObject that is already owned by the server. (#1500)
- Fixed NetworkManager.LocalClient not being set when starting as a host. (#1511)
- Fixed a few memory leak cases when shutting down NetworkManager during Incoming Message Queue processing. (#1323)

### Changed
- The SDK no longer limits message size to 64k. (The transport may still impose its own limits, but the SDK no longer does.) (#1384)
- Updated com.unity.collections to 1.1.0 (#1451)
