🥶 Announcing TypeScript 6.0 Over six months in the making, TypeScript 6.0 is designed to bridge the gap between its self-hosted compiler and the (almost ready) Go-powered native compiler of TypeScript 7.0 . There are new features (Temporal improvements, RegExp.escape, and more), but most important are the changes to help you prepare for 7.0: • Numerous default changes: strict is now true, module is esnext, rootDir defaults to ., and more. • A change that will affect many apps is types defaulting to [] rather than pulling in everything from node_modules/@types. • Numerous deprecations: the es5 target, emitting AMD, UMD, and SystemJS modules, --baseUrl, and others. • --stableTypeOrdering makes 6.0's type ordering behavior match 7.0's to help diagnose inference differences as you update.

🤟 Evolving the Node.js Release Schedule: A Work in Progress The Node.js team has long been discussing shifting Node to a new schedule of one major release per year (instead of two), removing the odd/even distinction, and making every release LTS (with a prior 11 months of alpha/current status). This is a preview post not intended for final publication till April, so things are subject to change (backup version). The Node.js Team
