Node.js 26.0.0: Temporal API Enabled, V8 14.6 Upgrades, End of Old Versioning
Node.js 26.0.0, released on May 5, activates the Temporal API by default, upgrades V8 to 14.6 with new Map upsert and Iterator.concat proposals, moves Undici to version 8, deprecates several legacy APIs, and marks the final release under the old version‑numbering scheme before shifting to yearly, calendar‑aligned releases.
