tslib is a runtime library containing helper functions for TypeScript, essential for projects leveraging TypeScript's advanced features. Both versions 2.5.1 and 2.5.2 are licensed under the permissive 0BSD license, making them highly suitable for a wide range of projects, including those with strict licensing requirements. Development is managed by Microsoft. Both versions are hosted on GitHub.
Version 2.5.2, released on May 18, 2023, is a minor update compared to version 2.5.1, released just a day earlier on May 17, 2023. While both versions include 13 files in the package, version 2.5.2 has a slightly larger unpacked size of 61569 bytes, compared to 60922 bytes in 2.5.1. This suggests that 2.5.2 includes some small improvements, bug fixes, or new features.
Developers using or considering tslib should typically opt for the latest version (2.5.2 at the time of writing) to benefit from the most up-to-date improvements and potential bug fixes. Given the tiny update, the differences are not expected to be ground-breaking. Upgrading should be seamless and not incur any breaking changes. If you are extremely sensible, you can review the specific commit history between version 2.5.1 and 2.5.2 on the GitHub repository to determine the precise nature of the changes.
