Kind: release · Impact: medium

## In brief

- Microsoft rolled out the TypeScript 7.0 RC in summer 2026, according to a DEV Community article.
- The headline and article claim a 10x performance boost; the excerpt gives no benchmark figures.
- The article notes that TypeScript was previously written in TypeScript itself, and the excerpt is cut off before explaining the change.

## Why it matters

If the performance claim holds, TypeScript projects could see faster type checking and builds, but the sources so far give no benchmarks to confirm the size of the gain.

## Versions

- TypeScript 7.0 RC
