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.
