Hey Everyone,

As I wrote about last month, the version of Node.js used in our -node variant Docker images has finally been updated.

You can read the blog post linked above but basically, with the CircleCI Docker Convenience Images, the -node (and thus -node-browsers) variant images have been updated from Node.js v8 to Node.js v10 to match the promotion of Node.js v10 as the new LTS version.
