tslib is a lightweight runtime library containing helper functions for TypeScript. Versions 1.9.1 and 1.9.2 of this package, crucial for projects utilizing TypeScript's advanced features, exhibit subtle yet potentially important differences. Both versions maintain the core functionality of providing essential runtime support, licensed under the permissive Apache-2.0. The size difference in the unpacked archives, 58108 bytes (1.9.1) versus 58208 bytes (1.9.2), suggests that the later version incorporates minor bug fixes or refinements to existing helper functions.
The release dates provide a clear timeline, with 1.9.2 arriving approximately two weeks after 1.9.1. Developers should note this relatively short interval, indicating that any changes likely address specific edge cases or performance optimizations identified in the earlier version. Based on the description and version bump alone, a direct upgrade to 1.9.2 appears generally recommended to benefit from these improvements, assuming no unforeseen compatibility issues arise within a project's specific dependency tree. However, the benefits might be marginal if a project is functioning perfectly with 1.9.1.
