Jest 26.4.0 represents a minor version bump over the previous stable release, Jest 26.3.0, in the popular JavaScript testing framework. Both versions share the same core description: "Delightful JavaScript Testing," underscoring Jest's commitment to providing a pleasant developer experience. A key similarity is the consistent use of the MIT license, ensuring broad usability and open-source compatibility for developers. The repository URL remains unchanged, indicating no fundamental shift in the project's hosting. The unpacked size and the number of files included in the packages are both identical, suggesting that the changes between versions didn't heavily impact the source code.
The primary differences lie in the version numbers of the core dependencies. Jest 26.4.0 relies on jest-cli and @jest/core at version ^26.4.0, while Jest 26.3.0 uses ^26.3.0 for the same dependencies. This version alignment within the major Jest package signifies coordinated updates to the command-line interface and core functionality. Developers upgrading from 26.3.0 to 26.4.0 can anticipate bug fixes, feature enhancements, or performance improvements within these core components. While import-local dependency remains unchanged at version ^3.0.2, the upgrade suggests subtle internal enhancements and refinements impacting the overall testing ecosystem. Finally, the release dates differ (August 12, 2020 for 26.4.0 vs. August 10, 2020 for 26.3.0), which may indicate hotfixes or features based on community feedback between the releases.
