Hello,

Node.js upstream has marked Node 4 as unsupported[0]. In addition, Node 5 and 7 have been unsupported for a long while now (since June 2016 and June 2017, respectively[1]). As such, in accordance with our Node.js version support policy[2], we plan to drop support for these Node versions in the upcoming 6.0 cycle. 5.1.x will be the last release line to support Node 4, 5, and 7.

Administrators still using these Node versions are encouraged to upgrade as soon as possible, as Node.js upstream is not providing security fixes for them anymore. Anyone impacted can consider using NodeSource[3] binary packages to get a newer Node or switching to our recently-announced Docker images[4], which use recent Node versions internally.

You can also read more about this change on our blog[5].

Cheers!

AJ
