Jest 27.4.0 arrived on November 29, 2021, succeeding version 27.3.1, which was released on October 19, 2021. Both versions maintain the core purpose of "Delightful JavaScript Testing" and share the same structure, licensing (MIT), and repository on GitHub. Key dependencies like jest-cli, @jest/core, and import-local are present in both, but updated to their respective version numbers aligning with the jest version itself. The consistent peer dependency on node-notifier across both versions indicates continued support for desktop notifications within the Jest testing framework.
The primary difference lies in the version updates of the core testing components. The jest-cli and @jest/core dependencies were bumped from 27.3.1 to 27.4.0, suggesting improvements, bug fixes, or new features within the testing environment itself. Furthermore, jest 27.4.0 introduces a slight increase in unpackedSize from 4679 to 4740, indicating a possible introduction of features or assets into the core library. Developers should consider upgrading to version 27.4.0 to leverage the latest enhancements within the Jest ecosystem related to the testing framework itself.
