Jest CLI version 28.1.0 introduces several updates and refinements compared to its predecessor, version 28.0.3, impacting developers using the popular JavaScript testing framework. A key change lies in the updated dependencies. Version 28.1.0 utilizes newer versions of Jest's internal packages, specifically @jest/core, jest-util, @jest/types, jest-validate, and @jest/test-result, all bumped to version 28.1.0. This indicates potential enhancements and bug fixes within Jest's core functionalities, type definitions, validation processes, utility functions, and test result handling. Developers can anticipate improved stability and performance due to these internal updates.
Furthermore, jest-config saw an update to version 28.1.0. This is important because jest-config handles the configuration of Jest, so upgrades there likely mean that things have changed with how Jest is configured in your project. The releaseDate also shows that there was about a week between the 2 updates. Although the update seems minor it may contains bug fixes, because of that, users of Jest are encouraged to upgrade to version 28.1.0 to benefit from the latest improvements and ensure compatibility across the Jest ecosystem.
