Babel-jest version 29.0.2 is a minor update to the popular Jest plugin, streamlining Babel transformations for JavaScript testing within the Jest framework. Comparing it to the previous stable release, version 29.0.1, the primary changes lie in updated dependency versions. Most notably, @jest/transform has been bumped from version 29.0.1 to 29.0.2, and babel-preset-jest sees an increment from 29.0.0 to 29.0.2. These updates likely incorporate refinements and bug fixes in the core Jest transformation logic and Babel preset tailored for Jest.
Developers using babel-jest can expect enhanced stability and potentially improved performance from these underlying dependency updates. The @jest/transform update likely brings general improvements to how Jest handles file transformations using Babel, while the babel-preset-jest update ensures the Babel configuration is optimally aligned with the latest Jest features. This ensures source code is compiled correctly before execution during tests.
While the core functionality of babel-jest remains consistent, upgrading from 29.0.1 to 29.0.2 is recommended to leverage the latest improvements and ensure compatibility with the broader Jest ecosystem. Both versions maintain the same peer dependency on @babel/core (version ^7.8.0), ensuring that developers can use babel-jest with a wide range of Babel configurations. The fileCount and unpackedSize remaining identical suggests the core file structure and included assets are unchanged. Finally, the release date delta confirms 29.0.2 is the newer version.
