nvm install 16. The Node.js blog post containing the changelog is available at https://nodejs.org/en/blog/release/v16.0.0.
Initially, Node.js v 16 will replace Node.js 15 as our ‘Current’ release line. As per the release schedule, Node.js 16 will be the ‘Current’ release for the next 6 months and then promoted to Long-term Support (LTS) in October 2021. Once promoted to long-term support the release will be designated the codename ‘Gallium’.
As a reminder — Node.js 12 will remain in long-term support until April 2022, and Node.js 14 will remain in long-term support until April 2023. Node.js 10 will go End-of-Life at the end of this month (April 2021). More details on our release plan/schedule can be found in the Node.js Release Working Group repository.
A new major release is a sum of the efforts of all of the project contributors and Node.js collaborators! Congrats to all who made it possible!
