This will cause all your installed Rubies listed in config.yml to use the updated SFX DevKit when building native gems and update the DevKit’s helper scripts (devkit.rb and operating_system.rb) with any new functionality. For safety, the original helper scripts are timestamp archived beside the new helper scripts. It’s always a good idea to review the two versions (and potentially make modifications) to ensure configuration specific to your system still works as expected.
