# Bun v1.3.5

**[Bun](https://daily.dev/sources/bun)** · 8 min read · 101 upvotes · 0 comments

## Summary

Bun v1.3.5 introduces a new Bun.Terminal API for pseudo-terminal (PTY) support, enabling interactive terminal applications. The release adds compile-time feature flags for dead-code elimination in the bundler, improves Bun.stringWidth accuracy for Unicode and emoji, and implements V8 C++ value type checking APIs. It also adds Content-Disposition support for S3 uploads and fixes environment variable expansion in .npmrc files. The update addresses 32 issues including networking bugs (macOS kqueue CPU usage, HTTP proxy authentication), Windows-specific crashes (WebSocket with compression, bunx panics), Node.js compatibility improvements, TypeScript definition fixes, and security issues with trusted dependencies.
