Full Changelog: https://github.com/rlabrecque/Steamworks.NET/compare/2025.162.1...2025.163.0

Unity upgrading notice: If you have a version of Steamworks.NET prior to 20.0.0 in your project, then you must first completely remove Steamworks.NET (aside from your usage of it) before upgrading to this version! As of Release 20.0.0 the minimum supported Unity Version is the LTS release "2019.4" due to the package support!

The prebuilt "Standalone" package is for non-Unity projects ONLY. If you're using Unity you probably want to use the Unity Package Manager URL below rather than the .unitypackage download
