The tslib package, a runtime library for TypeScript helper functions, saw a minor version update from 1.9.0 to 1.9.1. While seemingly small, such updates often contain crucial bug fixes and performance enhancements that impact the overall stability and efficiency of TypeScript-based applications. Both versions maintain the same core functionality as a supporting library and are licensed under Apache-2.0, ensuring broad compatibility and usage rights. The key difference lies in the release date, with version 1.9.1 arriving in May 2018, approximately four months after version 1.9.0.
For developers, choosing between these versions hinges on the nature of the fixes incorporated in 1.9.1. While the provided data lacks specific details regarding the included fixes or improvements, the short timeframe between releases suggests the update addressed an important issue that may have affected a subset of users or specific TypeScript compiler configurations. Developers encountering problems with version 1.9.0 or seeking the most up-to-date and stable release should consider upgrading to 1.9.1. Always consult the official tslib changelog to understand the specific changes in version and their impact on your project before upgrading. Also, both packages provide source code repository URL from Microsoft on GitHub.
