Hello,Node v4.6.0 represents a security release of the current Node.JS LTS line. The package is already in our APT repo and we plan to upgrade production clusters soon. Please test your services with the new release.For the SCB cluster, I have tested all of the services and there is currently a blocker for proceeding with upgrade~[1]. As soon as that one is resolved, I will be uploading and merging changes for SCB-bound services, since the switch must be done for all services at the same time. Even though I tested all of the services, I invite you to double-check and make sure that your respective service does not suffer from any problems or regressions because of the imminent switch.If you notice any problems or have any questions or concerns, please let me know ASAP.Cheers,Marko--Marko Obrovac, PhDSenior Services EngineerWikimedia Foundation
