Today node did an announcement of a security issue on its platforms: https://nodejs.org/en/blog/vulnerability/november-2018-security-releases/
Suggesting everybody to migrate to safer versions.
Version 8.14.0 is a new version that node has published in the last couple of hours in its public docker registry: https://hub.docker.com/r/library/node/tags/
Are you planning to do the same with: circleci/node:8.14.0 ?
Tried to pull it but it seems it’s not present yet.
