Node.js 27 launched in October 2026 as part of a new annual release schedule, introducing a null prototype for req.headers, a 4 GB heap default, V8 15.6, and powerful Iterator methods (zip, zipKeyed, join, includes). Other highlights include the unflagged Virtual File System, Math.sumPrecise(), native fs.glob(), mkstemp, and permission model expansion.
Background
Node.js follows an alternating Current/LTS schedule; v27 marks the start of a revised annual cadence where odd releases begin earlier in the cycle. The release pairs substantial API changes with infrastructure upgrades including V8 15.6 and OpenSSL 4.1.
