• method parameter metaDataOnly. Please audit your code for any calls to PICSGetProductInfo as the compiler will
• not warn you about this change. (#911)
• Changed SteamApps.GetPICSProductInfo signature to now use PICSRequest objects. (#1009)
• Removed some old non-Protobuf messages. (#1037)
• Updated nullability to match latest BCL annotations and to fix .NET 6 SDK analysis warnings. (#1049)
