## Summary

Bun 1.3 introduces zero-configuration frontend development with hot module replacement, a unified database API (Bun.SQL) supporting MySQL, PostgreSQL, and SQLite without external dependencies, and a built-in Redis client claiming 7.9x performance over ioredis. The release includes enhanced package management with dependency catalogs for monorepos, isolated workspace installs, and interactive dependency updates. Performance improvements include 10-30% reduced memory usage in frameworks like Next.js, 60% faster macOS builds, and 9% faster Express benchmarks. Breaking changes affect TypeScript types for Bun.serve() and SQL client usage patterns.
