## Releases

### v9.6.2

- Date: 2026-06-22
- Version: v9.6.2
- Original notes: https://github.com/TypeStrong/ts-loader/releases/tag/v9.6.2
- Permalink: https://whatsnew.fyi/product/ts-loader/releases/v9.6.2

- **changed** — Remove enhanced-resolve and semver from runtime dependencies, replace micromatch with picomatch
