TypeScript 6.0 released
TypeScript 6.0 has been released as a transitional step that aligns the compiler with upcoming performance improvements in the native Go rewrite scheduled for version 7.0. Significant configuration defaults have changed, requiring developers to explicitly set strict mode and list type packages since automatic discovery is now disabled. The release introduces support for modern standards including es2025 features and new Map methods while deprecating legacy module systems like AMD and ES5 targets. Users must update their tsconfig files immediately to handle breaking changes such as removed baseUrl functionality and the shift toward ESM defaults.
