## [1.0.0-beta.38] - 2025-09-15

📦 OXC Runtime Helpers Now Embedded

- Instant loading: Memory access instead of file I/O
- 91% smaller: From 229 KB external package to ~25 KB in binary
- Universal support: Works seamlessly in all environments including browsers
- Zero dependencies: Helpers embedded directly, no `@oxc-project/runtime` needed

⚡ Windows Performance Boost

- ~10% faster bundling on Windows
- Powered by `oxc-resolver` optimizations

Both improvements require zero configuration - just update to the latest version and enjoy! 🎉
