Overview
- Microsoft released TypeScript 7.0 on Monday, August 3, 2026, and the new tsc executable is distributed through the standard typescript npm package.
- The team published benchmarks showing typical 8x–12x full-build speedups, including an 11.9x drop on the VS Code build from 125.7 seconds to 10.6 seconds and about 18% lower aggregate memory use.
- Microsoft published a compatibility package, @typescript/typescript6, that provides a tsc6 binary and re-exports the TypeScript 6 API to keep existing tooling working during migration.
- Because 7.0 does not include a stable programmatic API, linters and many framework toolchains such as typescript-eslint, Vue, Svelte, Astro, MDX and Angular cannot adopt 7.0 until the planned 7.1 API is available.
- The native Go port began as an experimental preview in March 2025 and the TypeScript team says it will resume feature work and release updates roughly every three to four months to broaden ecosystem support.
