Bun 1.4.3 Released With Stability Fixes and Node.js API Improvements
Bun 1.4.3 introduces critical stability fixes for network and file system operations while enhancing compatibility with Node.js APIs.
Bun 1.4.3 is now available with stability improvements and bug fixes for the JavaScript runtime.
Updates address internal inconsistencies in network requests and file system operations. These changes eliminate documented crashes occurring under high-load conditions and ensure predictable behavior in tasks using the integrated toolchain.
Modifications to the internal fetch implementation and WebSocket handling correct issues where connection timeouts or headers failed to process according to standard protocols, causing intermittent failures in complex distributed applications. You can upgrade from Bun 1.4.x to incorporate these fixes.
Compatibility updates further align with Node.js API expectations by resolving discrepancies in buffer and stream data management, improving the transition path when porting applications from other environments. You should review the technical logs to see how updates impact project dependencies.
