• Rebuild and change path for ruby, jruby, bundler, node binaries and
  rails patching code
  • We identified a potential, but unlikely, attack vector in our continuous
    integration system. Our own auditing strongly suggests that this attack
    vector was not taken advantage of. However, out of an abundance of caution,
    we are rebuilding all buildpack dependencies that we maintain.
