Node.js 26.11.0 Released with New Buffer, HTTP, and Performance Hooks Features
Key points
- Added `isLatin1` and `stringLength()` to buffer module.
- Introduced `isValidHeaderName()` and `isValidHeaderValue()` for HTTP.
- Promoted Alpine Linux to Tier 2 support.
- Graduated `process.ref`/`unref` to stable.
Core Module Enhancements
Node.js 26.11.0 brings several new features to core modules. The buffer module now includes `isLatin1` and `Buffer.stringLength()` for more precise string length calculations. The HTTP module gains `isValidHeaderName()` and `isValidHeaderValue()` functions, allowing for better validation of HTTP headers.
Performance Monitoring Improvements
The `perf_hooks` module received multiple updates. These include fixing truncation for `monitorEventLoopDelay()` resolution, allowing `RecordableHistogram` to record zero values, and adding `histogram.diff()` and `histogram.snapshot()` methods. These changes provide more granular control and better insights into application performance.
Stability and Platform Support
Key features like `process.ref` and `process.unref` have been graduated to stable status, indicating their readiness for production use. Additionally, Alpine Linux has been promoted to Tier 2 support, signifying improved compatibility and support for this environment.
Other Notable Changes
Other updates include the addition of a `connectionWindowSize` option for HTTP2, renaming `DatabaseSync` and `StatementSync` in the SQLite module, and exposing size and count in heap profile output. These changes contribute to the overall stability, performance, and developer experience within the Node.js ecosystem.
