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. ## Full article daily.dev links to this article rather than hosting it.
