Node Version Manager is a tool that allows programmers to seamlessly switch between different versions of Node. The Technical Steering Committee of the Node.js Foundation oversees LTS release policies and strategies while the LTS Working Group actually manages support. Maintenance releases periodically receive critical fixes and documentation updates. Meanwhile, active versions get non-breaking backports of any changes implemented in the most current version a few weeks after release. Versions under LTS receive active support for 18 months followed by an additional 12 months of maintenance support.
