# Release notes {% hint style="info" %} Don't forget to check out our SDK [Upgrade Guide](/1.2.4/support/upgrading-unity-sdk.md) when switching versions! {% endhint %} #### 1.2.4 Published 10.07.2024 **Added** * New documentation structure. We hope it will improve the usability of our documentation significantly. * No changes to the SDK itself. #### 1.2.3 Published 01.07.2024 **Fixed** * When importing a project for the first time (no Library folder or Reimport All operation), the CoherenceSyncConfigRegistry (if missing) is created first. * Prefab Instance UUID property gets removed on Prefab Assets now. * RoomCreationOptions.FindOrCreate no longer hardcoded to false. * When a CoherenceSync has property overrides that can make networking fail, the inspector informs you and allows you to delete them. * Multi-Room Simulators: Local Forwarder no longer active on Cloud builds. * ReplicationServerConfig.AutoShutdownTimeout to add new Replication Server CLI flag `--auto-shutdown-timeout-ms`. * Disconnect and entity destroy operations release the entity ID now, allowing for scenarios where a huge amount of entities are created. * Customizable MTU in ConnectInfo. #### 1.2.2 Published 10.06.2024 **Added** * Replication Server has been upgraded to version 6.2.0 **Fixed** * Links in the SDK that got broken during the latest docs structure change now work. * Sending a command when CoherenceSync doesn't have a related CoherenceBridge no longer results in a null reference exception in the allowLocalOfflineCommand check. * Field names generated with baking are now more explicit so they don't lead to name collisions. * Time scale - speeding up, slowing down, and smoothing now works without errors. * Names in lobby are no longer silently truncated. An error is returned if the name or tag are too long. * Increased Entity Mapper range so Clients could gracefully handle more than 32 768 entities tied to them. * Backup World Data toggle setting can no longer go out-of-sync in SDK. #### 1.2.1 Published 13.05.2024 Leave feedback on the [forum thread](https://community.coherence.io/t/release-notes-1-2-1/521)!​ **Fixed** * Fixed an issue where a bunch of Preloaded Singleton-related exceptions would trigger when installing the package on fresh projects. ### 1.2 Published 09.05.2024 {% hint style="info" %} Take a look at the [highlights of 1.2](https://coherence.io/blog/news/coherence-1.2) in our blog. {% endhint %} Leave feedback on the [forum thread](https://community.coherence.io/t/release-notes-1-2/520)!​ **Added** * Improved [code stripping](/1.2.4/manual/advanced-topics/code-stripping.md) support for baked code. * ​[CoherenceSyncUtils API](https://unityapi.coherence.io/docs/v1.2.0/api/Coherence.Editor.CoherenceSyncUtils.html). * Support for [Unity's MPPM](/1.2.4/getting-started/setup-a-project/local-development/multiplayer-play-mode.md) and [ParrelSync](/1.2.4/getting-started/setup-a-project/local-development/local-testing-via-parrelsync.md) for better in-editor testing. * Schema inspector now shows all definitions, and links them with the related Prefabs. * On recompile, when **coherence** changes Prefabs, they will be listed on a pop-up. * CoherenceSync Inspector Header: Able to jump to the CoherenceSync definition while on inner child GameObjects. **Changed** * CoherenceSync Inspector Header has been reworked. It now works with GameObjects in Scenes and handles more Prefab configurations. * Reworked [CoherenceSyncConfigRegistry](https://unityapi.coherence.io/docs/v1.2.0/api/Coherence.Toolkit.CoherenceSyncConfigRegistry.html) and related APIs. * Gathered.schema definition names no longer include names of Prefabs or Unity components. * UDP is now enforced for Cloud Simulators. * Increased MaxStablePingDeviation for ping stability. * `Client.SetTransportFactory` no longer accepts null argument. Use the new `Client.SetTransportType` instead. **Fixed** * Reliability of automations around `[Sync]` and `[Command]` has been fixed. * Variables in Configure Window with the same name as Animator parameters could previously show the Animator icon. * Fixed code generation with lots of definitions. * Configure Window rendering improvements - takes less time to render now. * Allocations made per frame by CoherenceLoop even when disconnected. * Fixed stutter during reparenting. **Removed** * CoherenceSyncConfigManager. See [CoherenceSyncConfigRegistry](https://unityapi.coherence.io/docs/v1.2.0/api/Coherence.Toolkit.CoherenceSyncConfigRegistry.html) and [CoherenceSyncConfigUtils](https://unityapi.coherence.io/docs/v1.2.0/api/Coherence.Editor.CoherenceSyncUtils.html). * ​[CoherenceSyncConfigRegistry](https://unityapi.coherence.io/docs/v1.2.0/api/Coherence.Toolkit.CoherenceSyncConfigRegistry.html): save modes. Now CoherenceSyncConfigs are referenced exclusively as external assets in Assets/coherence/CoherenceSyncConfigs. The registry can still read sub-assets, but this functionality will be deprecated in future versions. * Deprecated members since 1.0 and earlier. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
