Node.js — Node.js 26.0.0 (Current)

Node.js 26.0.0 has been released as the new 'Current' version, with LTS planned for October. Key highlights include the Temporal API enabled by default (a modern replacement for the legacy Date object), V8 engine updated to 14.6 (adding Map.prototype.getOrInsert() and Iterator.concat()), and Undici updated to 8.0.2. Breaking changes include removal of legacy _stream_* modules, removal of http.Server.prototype.writeHeader(), runtime deprecation of module.register(), and removal of --experimental-transform-types flag. Several crypto API changes are also included, such as unified asymmetric key import and ML-KEM/ML-DSA pkcs8 export format changes.
