The Node.js team has recently released a new major version of Node.js - Node v8.0.0.
It is going to be the next Long Term Support (LTS) version from October 2017 onwards, following the current LTS version 6, and it brings a lot of new stuff and many improvements to the table.
As always, you can download Node.js v8.0.0 from the official download page.
