Bun Releases 1.39 Adding Concurrent Script Execution
Bun has released version 1.39 following its recent acquisition by Anthropic, and the update is available now. The release adds Foreman-style prefixed output to run multiple package.json scripts concurrently or sequentially, SIMD-accelerated Markdown-to-HTML rendering with 3–15% throughput gains, plus Bun.Archive and Bun.JSONC.parse APIs. The project remains open-source under the MIT license and continues focusing on performance and Node.js compatibility.
Scoring Rationale
Official release delivers practical developer features and measurable performance gains, but represents incremental tooling improvement rather than paradigm shift.
