1.4

Published 30.01.2025

Check out the highlights in our 1.4 blog post and leave feedback in the forum thread!​ We have also updated the Upgrade Guide.

Added

• Ordered commands.

• Added safeguards to make sure bindings are not affected by automated processes when CloneMode.Enabled is set to True.

• Added a new context menu item into the Optimization window, that can be used to apply optimizations for a binding from a base Prefab into all of its variants.

• Support for launching self-hosted Replication Server in IL2CPP builds.

• CoherenceBridge inspector now shows the transport used.

• CoherenceSync and Baking now support any valid C# identifier name. This includes components, variables, commands and command parameters.

• Prevented Unity linker from stripping code from coherence's assemblies and causing functionality to sometimes break when using high stripping levels.

Changed

• Local simulator build remembers the last path and no longer prompts you when you re-build for the current session.

• Changed the Matchmaking Sample to only write updates to the console when the number of players in the lobby changes.

• Simplified log-in API.

• If Project Settings > coherence > Logs > Console Level (Editor) is set to Debug, the COHERENCE_LOG_DEBUG symbol will be added to Simulator builds before compilation.

• The configuration button in the coherence Sync editor window is now enabled in play mode.

• The rooms sample dialog displays a warning if the 'Auto Login As Guest' flag is unchecked.

• When replacement strategy is replace then the Entity is now disabled in the scene instead of left running.

• "Run in background" warning will only show if the bridge is connected.

• Building a local Simulator will auto-populate the path in the Run Local Simulator Build section of the coherence Hub.

• Added method for updating arguments to the SimulatorUtility to enable using the Simulator utility without rebuilding local Simulators.

• Improved error message if an attempt is made to transfer an orphaned entity.

• Removed an error when destroying an entity the Client core didn't know about anyway.

• Added description property to ITransport and an accessor in IClient. These are API breaking changes.

• Backup world data has been placed behind a feature flag and disabled by default.

• Improved CoherenceLiveQuery inspector.

• WebGL now uses makeDynCall() and UTF8ToString(). See Replace deprecated browser interaction code.

Fixed

• Fixed issue with errors appearing when selecting a Simulator build in coherence Hub > Simulators.

• Fixed InvalidCastException that could happen in some rare situations when pressing the Sign Up / Login In button in coherence Hub.

• Log an error when a network entity create arrives with an unknown asset ID.

• Fixed warnings about inconsistent line endings when baking scripts on a Windows computer.

• Selected organization and project are no longer cleared when logging in and out.

• Fixed the validation to allow Only predict with input authority to be selected if a CoherenceInput was attached to a game object.

• Fixed resource leaks when a CoherenceBridge is destroyed.

• Fixed AuthToken.LoginAsGuest and LoginWithPassword failing the first time they are called if there's no session token.

• Parenting a run-time instantiated entity to an existing nested Prefab race where the entity might not appear.

• Culture settings could cause issues launching Replication Server from the menu/Hub. Command line options are now culture-independent.

• Fixed an issue adding CoherenceInput to an unsaved prefab that might cause a nullref error to be displayed in the console.

• Fixed matchmaking sample showing warnings for obsolete Unity classes.

• Re-compiling a script could display an "Organization not set" warning in the project window if the coherence Hub was not open.

• Removing invalid bindings stability.

• Button style for Run Local Simulator in Hub's Simulator tab.

• Changing interpolation from/to none hints a re-bake is required.

• Warn about re-bake needed when creating CoherenceSync duplicates or variants.

• HandleDisconnect exception handler now logs the correct AuthorityType.

• Unique nested Prefabs would sometimes not replicate the children correctly.

• Revisited stability of bindings around edge cases (invalid bindings, missing components, null references, duplicates...).

• Fixed issue where removed components from Prefab instances could not be repaired.

• Missing components are now displayed correctly in the Fix Prefab Instance dialog.

• Fixed an issue when a local Simulator build is incorrectly marked as an invalid binary by MacOS running on Apple Silicon.

• Avoid Prefab validation and updating when entering Play Mode.

• Fixed issue where a replaced duplicate could be disabled in a bad network environment.

• Commands referencing yet unknown entities are now being held onto until the referenced entities are received.

• Fixed the simulator build path for Windows.

• Name collision when using the lobbies sample if a class called Player exists in the project.

• Compilation error when using a version of Test Framework below 1.4.4.

• When using [Sync] and [Command] attributes, Prefab Variants will no longer create unnecessary binding overrides.

• Fixed exception when changing INetworkObjectProvider (CoherenceSync editor's "Load via" setting) when the Prefab is within a subfolder (for example, Resources/Prefabs).

• Missing reference when joining a cloud room on certain projects.

• Upload build button disabled until build folder is selected again if project changes.

• Interpolation overshoot is now limited instead of infinite.

• Lowered interpolation latency and improved on some edge cases.

• Improved reliability of CoherenceBridge's 'Auto Login As Guest' behavior.

• Added message to the console if the project is run after an upgrade without baking first.
