@benridley Thanks for opening this issue. We are aware of the deprecation warnings, which are coming from one of Bolt's dependencies, not Bolt itself. We've opened a ticket with the gem's maintainer, which you can track here: zentourist/gssapi#35

Thanks @beechtom, glad to hear it's got a path to resolution. Feel free to close this, otherwise I'll leave it open for tracking and others who might come across this.
