Announcing TypeScript 7.0

By BIOS Founding Team

Announcing TypeScript 7.0

TypeScript 7.0 is the first stable release built on the new native Go-ported compiler, delivering full-build speedups of roughly 8x to 12x on major codebases compared to the JavaScript-based compiler.

It adds parallelized type-checking via new --checkers and --builders flags and a rebuilt --watch mode. Notably, 7.0 ships without a programmatic API (planned for 7.1), so tools like webpack and typescript-eslint must stay on TypeScript 6.0 for now.
