# Bun v1.3.4

**[Bun](https://daily.dev/sources/bun)** · 8 min read · 57 upvotes · 3 comments

## Summary

Bun v1.3.4 fixes 194 issues and introduces several new features. The release adds URLPattern API for declarative URL matching, fake timers for the test runner to control time in tests, and custom proxy headers in fetch requests. It fixes a critical http.Agent connection pooling bug that prevented connection reuse. Standalone executables now skip loading config files at runtime by default for better performance. The update includes SQLite 3.51.1, console.log %j format specifier support, and numerous bugfixes across testing, bundler, Windows compatibility, Node.js APIs, and FFI.
