Changes announced for Protocol Buffers on June 16, 2026.

Dropping C# NuGet package author signing

We will be dropping C# author signing for our NuGet packages (Google.Protobuf and Google.Protobuf.Tools) in future releases.

Previously, we used a Google-owned certificate to author-sign NuGet packages. NuGet packages will no longer contain a Google author signature. They will continue to be repository-signed by nuget.org upon upload.

This change aligns with similar signing changes being made to the gRPC NuGet packages.
