What's new

… or old, really. 5.0.0 was shipped approx 1 year ago 🙃

Deprecation notice:

• Last published version of the CLI tool (a.k.a dotnet retire) will be 5.0.0. See #75 by @johnkors
• The Runtime Checkers lives on in this repo, as the security team of the .NET SDK does not want this feature.
