Node.js version 22.19.0 (LTS) has been released, introducing a range of significant enhancements and updates. This release notably includes new features in the CLI, such as the ability to utilize system CA certificates with the setting `NODE_USE_SYSTEM_CA=1` and support for `${pid}` placeholders in CPU profiling names. Moreover, improvements have been made to various modules, including DNS and HTTP functionalities, enhancing their performance and usability.
Key changes in this version encompass:
- CLI Enhancements: Introduction of new environment variables and placeholders for profiling.
- Security Improvements: Support for using system CA certificates in TLS contexts.
- Performance Optimizations: New settings in HTTP servers, like `server.keepAliveTimeoutBuffer`, and additional features in the DNS module for max timeout settings.
- Documentation Updates: Corrections to release verification instructions, clarifications on memory leak threat models, and other enhancements to improve overall user guidance.
The release also included various commits addressing bugs, performance, and documentation improvements. For instance, the `threadCpuUsage` feature has been added, allowing developers to gain insights into CPU usage per thread, and updates to the `zlib` module now support dictionary compression and decompression methods.
This release marks a crucial step in ensuring that Node.js remains robust and user-friendly for developers by continually incorporating feedback and addressing existing issues.
