Good morning, this is your Node.js development briefing for April 26th, 2026.
Today's activity included ten commits focused on performance improvements and developer tooling enhancements.
Tim Perry's commit increased the HTTP keepAliveTimeout default from 5 to 65 seconds. This change aligns Node.js with common load balancer configurations that typically use 60-second timeouts, reducing connection drops in production environments. The update affects the core HTTP server implementation and required…
Ilyas Shabi added new CPU profile options to the V8 module, expanding profiling capabilities for performance analysis. The implementation includes a new internal CPU profiler module and extends both the main V8 API and worker thread profiling features.
Gürgün Dayıoğlu optimized URLSearchParams performance by improving duplicate handling in set and delete operations. The changes include a new mutation benchmark and enhanced internal URL handling logic.
Filip Skokan enhanced the testing infrastructure by adding support for non-default OpenSSL versions in the shared workflow. This expands compatibility testing across different OpenSSL configurations using new GitHub Actions and Nix tooling.
