# Bun v1.3.11

**[Bun](https://daily.dev/sources/bun)** · 17 min read · 89 upvotes · 2 comments

## Summary

Bun v1.3.11 ships with 105 bug fixes and several new features. New APIs include Bun.cron for OS-level cron job scheduling (crontab/launchd/Task Scheduler), Bun.sliceAnsi for ANSI and grapheme-aware string slicing, and richer metadata in Bun.markdown.render() list callbacks. The release adds --path-ignore-patterns for bun test, native Windows ARM64 shims for node_modules/.bin, and fixes dgram UDP socket bugs on macOS. Notable bug fixes cover fs.openSync numeric flags on Windows (unblocking tar@7), http2 WINDOW_UPDATE stalling, CRLF injection in HTTP headers, bundler bytecode/barrel/import-attribute issues, CSS unicode-range and mask parsing, bun install hang scenarios, and dozens of Node.js compatibility improvements across crypto, streams, fs, and more.
