Release Notes 2023.1.3.8471.2970

Each version of this integration matches a specific build of Unreal Engine. Here is what has changed in the 2023.1.3.8471.2970 release of the integration (in addition to upgrading to the new Unreal build).

Note:
This integration does not support experimental Unreal Engine features.
Note:
  • This integration was compiled against Unreal Engine version 5.2, 5.3 and 5.4 Preview. It was tested against Unreal Engine 5.3 and 5.4 Preview.
  • Unreal Engine 5.4 Preview support is ready for development. It was tested both in editor and in game for Windows and Mac. It was not tested on consoles or mobile devices. We do not recommend using a preview version of Unreal Engine in production.

For earlier versions, please refer to Previous Release Notes.

New Features

  • WG-66631 The Integration now supports Wwise SoundEngine in Profile and Debug configurations on Linux, in addition to the Release configuration. It is also possible to connect to Debug and Profile configurations with the Profiler.
  • WG-69218 Added support for SoundEngine, FileHandler, and ResourceLoader Low Level Memory (LLM) tracking through Audio/Wwise group.
  • WG-69920 Added overridable move operation to Reconcile. This operation does nothing without overriding it.
