2019 Change Log

Mirror uses semantic versioning, and the versions shown here are those that were published to the Asset Store, and occasionally major version bumps happen mid-month between store submissions and are therefore not individually shown here.

v6.3.0 - 2019-Dec-09

• Added: SyncMode selector now works for components on any scene objects owned by a client in addition to the player object, e.g. pets.

• Added: MessageBase now fully supports inheritance.

• Added: Room example now has UI button for host to return all clients to the Room scene and other improvements.

• Fixed: ReplacePlayerForConnection now works for existing scene objects as long as another player doesn't own the targeted object.

• Fixed: isClient and isServer are now true for networked objects in Start and OnStartClient / OnStartServer, respectively.

• Fixed: hasAuthority is now set before OnStartClient and OnStartLocalPlayer are invoked.

• Changed: connectionToClient is now used to assign client authority.

• Changed: In many respects, the Host player acts a lot more like a client and will reveal bugs better.

• Changed: ReplacePlayerForConnection now has an optional bool to retain authority of the previous object (default = false).

• Removed: NetworkServer.SpawnWithClientAuthority is deprecated in favor of overloads of NetworkServer.Spawn.

v5.0.2 - 2019-Nov-03

• Added: SyncList and SyncSet custom Equality Comparer support.

• Added: Custom serializers may be implemented for any type in Cmd's and Rpc's.

• Added: Fallback Transport.

• Fixed: SyncVar hooks are no longer called in Host if no change.

• Fixed: Network Identity no longer throws a null reference exception in RemoveClientAuthority.

• Fixed: Server transport now suspended during scene change to prevent erroneous messages.

• Fixed: SyncList, SyncDictionary and SyncSet now use a custom IEnumerator to avoid memory allocation.

• Fixed: sceneID is no longer reset in certain cases when editing a prefab.

• Changed: Commands no longer bypass serialization for Host player, making debugging easier.

• Changed: Local connections now maintain their own message queue.

• Changed: Transport.Available is now abstract.

• Added: Transports now include channel in profiler events.

• Added: Transport abstract class now supports sending a message to a list of connection id's.

  • Some transports may still have a little garbage allocation yet.

• Changed: Deprecated the AddPlayerMessage extraMessage byte[] in favor of an easier approach to Custom Players.

  • This is a breaking change: The virtual method OnServerAddPlayer loses the AddPlayerMessage parameter.

• Changed: NetworkIdentity.RemoveAuthorityForConnection is now easier to use: no need to supply the current "owner" anymore.

• Changed: Renamed NetworkConnection.playerController to identity ... see Deprecations for details.
