End of Life

The end-of-life date for this agent version is July 29, 2019. To update to the latest agent version, see Update the agent. For more information, see End-of-life policy.


  • HTTPClient and Curb support

    The Ruby agent now supports the HTTPClient and Curb HTTP libraries! Cross application tracing and more is fully supported for these libraries. For more details see

  • Sinatra startup improvements

    In earlier agent versions, newrelic_rpm had to be required after Sinatra to get instrumentation. Now the agent should start when your Sinatra app starts up in rackup, thin, unicorn, or similar web servers.

  • Puma clustered mode support

    Clustered mode in Puma was not reporting data without manually adding a hook to Puma's configuration. The agent will now automatically add this hook.

  • SSL certificate verification

    Early versions of the agent's SSL support provided an option to skip certificate verification. This option has been removed.
