Hello, As of the release of service-runner v2.3.0~[1] earlier today, we are no longer supporting Node.js v0.1x platforms. The minimum Node version needed to power your services is now set at v4.2.2, but we encourage the library's users to develop and run their services on Node v6.x, the current Node TLS release. If this change is affecting your services in a negative way, please let us know here on-list or by filing a task in Phabricator against the service-runner tag~[2]. Best, Marko Obrovac, PhD Senior Services Engineer Wikimedia Foundation [1] https://github.com/wikimedia/service-runner/releases/tag/v2.3.0 [2] https://phabricator.wikimedia.org/project/board/1062/
