When does Node.js 20 reach end of life?

What it does

  • Shows whether a version of a product has reached end of life, with its end-of-life and LTS dates
  • Lists the release cycles of a product that are still supported, newest first, with the latest patch
  • Reads the runtime pins in a repo (Node.js, Python, Go, Ruby, PHP, .NET, Docker images) and flags any past end of life
  • Looks up an SPDX license by identifier or name: OSI approved, FSF free, deprecated or not
  • Shows the first release of each major browser that supports a web feature, and its Baseline status
  • Looks up an RFC by number or title words: status, abstract, and the RFCs that obsolete or update it
