tslib is a crucial runtime library for TypeScript projects, providing essential helper functions that enable TypeScript code to function correctly across different JavaScript environments. Version 2.6.1 and 2.6.0 share the same core purpose: offering these lightweight, reusable helpers, licensed under the permissive 0BSD license, making it ideal for incorporating into any project without licensing concerns. Both versions are maintained by Microsoft and are available for download from the npm registry.
The key differences reside in the details. Version 2.6.1, released on July 24, 2023, has a slightly larger unpacked size of 83986 bytes compared to version 2.6.0's 83488 bytes, released on June 26, 2023. While both have the same 14 files in the package, this size difference indicates that some of the helper functions or internal optimizations might have undergone minor updates or bug fixes. For developers, upgrading to version 2.6.1 is generally recommended to benefit from these potential improvements. Given the nature of tslib, changes are often related to improved compatibility with new TypeScript versions and enhanced support for different target JavaScript environments. Therefore, staying current ensures your TypeScript code remains robust and portable, leveraging the latest refinements in the helper library. While the description of the package remain the same, runtime libraries often receives micro-optimizations and version 2.6.1 may contain micro-optimizations and important bugfixes for some edge cases.
