A Post Mortem of What Broke Node v22.5.0 — The ‘Current’ release line gives us the latest Node has to offer, at the risk of sometimes including show-stopping bugs too, and so it went with v22.5.0. Node v22.5.1 was released to fix the error. Matthew McEachen wrote further about his experience in encountering the bug.

Node.js v22.5.0 (Current) Released – But Don't Install It! — A notable release for three reasons: first, the WebSocket feature in node:http is now exposed.
