Unreal Engine 5.2 Preview

Preview 2 for 5.2 is now live! Thanks for helping us improve the 5.2 build before its official release. As a reminder, the Preview builds are for testing only, and should not be used for the active development of your project.

For a list of known issues affecting this latest preview, please follow the links provided on the first post in this thread.

NOTE

  • Compiling in the installed engine using the Visual Studio on 2019 toolchain may encounter linker errors, these will be addressed for the full release of 5.2. The current workaround for Preview 2 is to compile with VS2022.
  • Intel Mac users may see issues with the engine crash reporting window having less useful data than normal. This will be fixed for the full release.

Thanks everyone!

Fixed in Preview 2
