Added a static delegate to name Quantum entities: EntityRef.GetEntityNameUser can return a custom EntityRef string representation otherwise the default EntityRef.ToString is used. The entity name is displayed in FramePrinter, QuantumStateInspector and EntityViewUpdater
Added an option to split the generated code into multiple files: GeneratorOptions.MaxLinesPerFile sets the intended maximum number of lines per file (int.MaxValue by default). If a file goes above the limit, additional files with .Part<N> suffix will be created. Actual files may be slightly longer or shorter then intended max line count because it estimates line counts ahead of time.

3.0.0

Breaking Changes

The Quantum SDK is now a unitypackage.
Renamed PhotonDeterministic.dll to Quantum.Deterministic.dll and QuantumCore.dll to Quantum.Engine.dll.
Upgraded network libraries to Photon Realtime 5 (see Realtime changelog separately).
All Unity-only scripts have been put in Quantum namespace and have been given Quantum prefix (e.g. MapData -> QuantumMapData, EntityPrototype -> QuantumEntityPrototype).
The PhysicsCollider 2D and 3D components now have a field called Layer Source which defines where the layer info should come from. This might require colliders layers to be set again;
The AssetBase class is no longer functional.
AssetObject now derive from UnityEngine.ScriptableObject. This means that there is no longer the need for AssetBase wrapper and all the partial AssetBase extensions need to be moved to AssetObject definitions. Tools that migrate asset data without data loss are provided on our website.
AssetObjects need to be created with AssetObject.Create<T> or T.Create.
To add a new list of assets (e.g. with Addressables), mark a method with [QuantumGlobalScriptableObjectLoaderMethod] attribute.
IAssetSerializer interface changed, it also deals with RuntimePlayer and RuntimeConfig serialization
AssetObjects referencing other AssetObjects directly (not by AssetRef<T>) are supported, but will no longer be fully serializable by the default IAssetSerializer. This should be a concern for when any non-Unity runner is used or such assets are used in the DynamicDB.
More consistent DynamicAssetDB behavior - assets can be added and disposed only during verified frames. Also, AssetObject.Disposed is called whenever a dynamic asset is disposed. Previous behavior can be restored with QuantumGameFlags.EnableLegacyDynamicDBMode game flag
Unless QuantumGameFlags.EnableLegacyDynamicDBMode is used, all assets in the DynamicAssetDB will get disposed upon shutting down simulation.
Removed "standalone assets" / QPrefabs. They have been fully replaced with standalone prototypes. All _data files should be removed.
Removed built-in support for AssetBundles.
RuntimeConfig and RuntimePlayer are serialized with Json when send to the server.
Added the $type property to Json serialized RuntimeConfig and RuntimePlayer to be able to deserialize the file outside of Unity, use QuantumUnityJsonSerializer.SerializeConfig(Stream stream, IRuntimeConfig config) to export RuntimePlayer and RuntimeConfig or add "$type":"Quantum.RuntimeConfig, Quantum.Simulation" or "$type":"Quantum.RuntimePlayer, Quantum.Simulation" to the respective Jsons.
MapDataBakeCallbacks implemented in a custom assembly it has to be made known by adding this [assembly: QuantumMapBakeAssembly] to the script.
Changed the timing around the GameStarted callback. It is now only called once per started Quantum session and, when waiting for a snapshot, it will be called after the snapshot has arrived with isResync = true.
Collections used in events are now passed by their appropriate pointer type (e.g. list<T> -> QListPtr<T>). Was: Ptr
Frame.Heap is no longer a Heap* but instead a reference to a managed FrameHeap instance, which shares the same API and adds allocation tracking capabilities. Direct usages of frame.Heap-> can be replaced by frame.Heap. instead.
The default backing type for flags in DSL is now Int32 (was: Int64)
Added the isResync parameter to the GameStarted callback (which is true, when the callback is invoked after the game has been re-synced for example after a late-join).
Changed QuantumNavMesh.ImportSettings.LinkErrorCorrection type from bool to float (representing a distance).
NavMeshRegionMask.HasValidRegions() now returns true for the "MainArea", use HasValidNoneMainRegion instead to only query for non-MainArea regions
AppSettings.RealtimeAppId was replaced by AppSettings.QuantumAppId, the Unity inspector will automatically swap them when the PhotonServerSettings asset is inspected.
Changed the replay file format and renamed it to QuantumReplayFile, marking the old name obsolete. Asset DB, RuntimeConfig and InputHistory are now saved with a Json friendly wrapper that works around how verbose the Unity Json tool saves byte arrays, reducing the replay file size when saved in Unity a lot,
The Quantum3 server will automatically block all non-protocol messages and all Photon Realtime player properties. Unblock them using the Photon dashboard and set BlockNonProtocolMessages and BlockPlayerProperties to false.
Removed DeterministicGameMode.Spectating (use Multiplay) because all online Quantum simulation are started in spectating mode by default until a player is added.

What's New

Added input delta compression.
Increasing minimum Unity version to 2021 LTS.
New start online protocol to support adding and removing players at runtime.
Added Quantum webhooks for the Photon Public Cloud.
Increased maximum player count to 128.
Added support for up to 512 components (use #pragma max_components 512 to enable)

Added the Asteroid game sample that can be installed with the QuantumHub.
Added a new GUI to toggle Quantum gizmos.
Added async support for connection handling.
Added support for assets that are neither a Resource nor Addressable. Direct references to such assets are stored in QuantumUnityDB.
QuantumUnityDB.Get[Global]AssetGuids - ability to iterate over GUIDs, based on asset types.
Added support for netstandard2.1.
Added full support for Odin inspector.
Polished Quantum Unity inspector and added code documentation foldouts.
Added a Newtonsoft-powered Json deserializer can now read [SerializeReferences] (uses the Quantum.Json.dll dependency for non-Unity platforms).
Added a data-driven way of adding systems (see SystemsConfig.asset).
Added AllowedLobbyProperties dashboard variable to restrict lobby property usage for Photon matchmaking.
Added Quantum.Log.dll dependency, which introduces the Quantum.LogType and can clash with UnityEngine.LogType when migrating.
Added Quantum debug dll toggle to switch between Debug and Release Quantum dlls in Unity
Added position and rotation teleport support for Transform2D, Transform3D and QuantumEntityView.
Increased max navmesh region count to 128.
Added Frame.PlayerConnectedCount.
Added FrameThreadSafe.GetGlobal() extension method.
Added EntityViewComponents, a quick way to add view logic to the Quantum entity views.
Added entity view pooling (add QuantumEntityViewPool to the EntityViewUpdater game object)
Added dotnet Quantum dll build (see QuantumDotnetBuildSettings asset).
Added a dotnet console replay runner app project that is generated to the non-Unity simulation project.
Added a tool to quickly convert Unity colliders to Quantum colliders GameObject/Quantum/Convert Colliders.
Added Quantum Unity script templates.
Added DynamicMap core type, a specialization of Map as a Dynamic Asset capable of triggering internal updates when modifying static colliders and of serializing runtime mesh data.

Changes

Unified CodeGen tools into one that is used from the UnityEditor.
Unified QuantumRunner and SessionContainer into the SessionRunner class and moved it to the QuantumGame project.
Component prototype suffix has been changed from _Prototype to Prototype.
Component prototype wrapper prefix changed from EntityComponent to QPrototype (e.g. EntityComponentTransform2D -> QPrototypeTransform2D).
Frame.Assets is now obsolete. Use Frame.FindAsset<T> instead.
AssetObjectConfigAttribute is obsoleted and no longer functional.
AssetObject is no longer restricted to being in the same assembly as Quantum simulation code. If the simulation code needs to access such assets, it can either use a base class or an interface. This allows AssetObjects to be extended with any Unity-specific data.
AssetRefT generated types are now obsolete, use AssetRef<T> instead.
asset T; and import asset T; are no longer needed in .qtn files. Any type derived from AssetObject is already a fully functional Quantum asset now and can be used with AssetRef<T> fields.
AssetObject.Guid is now deterministic by default, based on Unity's GUID and fileId. When needed can be overridden (e.g. for assets imported from Quantum 2.1) - such overrides are stored in QuantumEditorSettings. Turning AssetGuids deterministic speeds up QuantumUnityDB by an order of magnitude.
UnityDB has been obsoleted and AssetResourceContainer has been removed. QuantumUnityDB replaced both and uses more consistent method naming.
Prototype assets for new prefabs are created as standalone assets, with EntityPrototype suffix and qprototype extension. This fully decouples loading prototypes during simulation from their source prefab, improving asset load times and avoiding deadlock issues with Unity's job system.
All Quantum assets located in asset search paths are now marked with QuantumAsset label.
Moved NavMesh baking to the Quantum Simulation project to bake parts deterministically (not the Unity navmesh export).
Removed the MovementType.DynamicBody and MovementType.CharacterController2D from the NavmeshAgentConfig. Select MovementType.Callback instead and perform movement during the ISignalOnNavMeshMoveAgent callback. The removed options were only good for prototyping and led to a lot of questions.
Changed QuantumNavMesh.BakeData and related data structures to only use fixed point vectors.
Replaced non-deterministic code (Triangle Normal Computation) in BakeNavMesh() with fixed point math.
Moved navmesh link detection and error correction from BakeNavMesh() to ImportFromUnity(), StartTriangle and EndTriangle now are set on BakeData.Links.
The MainArea of the navmesh now has its own valid navmesh region (always index 0) and can be toggled on/off and can be properly used for navmesh queries like LineOfSight() or FindClosestTriangle().
Changed BakeNavMesh signature to only use relevant data types.
Replaced the signal OnPlayerDataSet(PlayerRef player) with OnPlayerAdded(PlayerRef player, bool firstTime) where firstTime signals this is the first time that this player was assigned..
Added OnPlayerRemoved(PlayerRef player) signal.
Added a parameter to the GameStarted callback (isResync: true, when the callback is invoked after the game has been re-synced for example after a late-join).
Removed the ReleaseProfiler configuration from the code solutions and replacing it with a flag in StartParameters.GameFlags called QuantumGameFlags.EnableTaskProfiler.
Removed API that was deprecated in Quantum 2.1.
All Quantum Unity MonoBehaviours now derive from QuantumMonoBehaviour.
All Quantum Unity ScriptableObjects now derive from QuantumScriptableObject.
The state inspector now shows all relevant configs when selecting the Runner.
Restructured the Quantum Unity menus.
Navigation.Raycast2D() provides information about the border index that generated the closest hit.
Reduced the navmesh binary asset size, control the serialization options under NavMesh.SerializeType. By default meta data is now recomputed during runtime, set to NavMeshSerializeType.FullWithMetaData to disable it.
Drawing debug shapes for development builds must now be opted in by defining the QUANTUM_DRAW_SHAPES define (QuantumEditorSettings has a shortcut to toggle it).
Quantum runtime logging can now be toggled by a LogLevel inside the EditorSettings, the default is WARN.
The context LayerInfo is now exposed in FrameThreadSafe.Layers property, similarly to Frame.Layers.
Quantum.TypeUtils is now obsolete

What's New

FP.FromRoundedFloat_UNSAFE
Extension methods ToRoundedFP, ToRoundedFPVector2 and ToRoundedFPVector3
2D and 3D Compound Shape method to ReserveCapacity

Unlit/Quantum Debug Draw renamed to Unlit/Quantum Debug
Moved the shader file QuantumDebugDraw.shader to Assets/Photon/Quantum/Runtime/RuntimeAssets
The Quantum Hub installation button is no longer disabled when the installation is detected as complete
Iterating DynamicAssetDB is much more performant, but still allocates
IResourceManager extensions now use generics to avoid virtual calls
Quantum.Json and standalone projects now support ISerializationCallbackReceiver interface
Added Odin.Serialization and Odin.Attributes assembly references to Quantum.Simulation. As all assembly references are optional (unless there are compile errors), a project does not need to have Odin installed
Photon.Deterministic.PersistentMap refactored. It is no longer IEquatable, implements visitor pattern and enumeration is much more performant, thought it still allocates a bit
Assets in DynamicAssetDB are now reference-counted. Counters are shared by DB instances that are linked to each other due to copy constructor or DynamicAssetDB.CopyFrom. Assets are disposed when their reference count drops to zero, due to DynamicAssetDB.ReplaceAsset, DynamicAssetDB.DisposeAsset, DynamicAssetDB.Dispose (entire db disposal) or DynamicAssetDB.CopyFrom (due to releasing the old state). Note that none of this applies if legacy mode is used
