2018-12-03, Version 6.15.1 'Boron' (LTS)

Notable Changes:

This is a patch release to address a bad backport of the fix for "Slowloris
HTTP Denial of Service" (CVE-2018-12122). Node.js 6.15.0 misapplies the headers
timeout to an entire keep-alive HTTP session, resulting in prematurely
disconnected sockets.
