Jest CLI version 27.0.1 represents a minor update following version 27.0.0, both serving as command-line interfaces for the popular JavaScript testing framework, Jest. This update primarily refines the core functionalities and dependencies for improved stability and performance. Key differences lie in the updated dependency versions. Notably, @jest/core, @jest/types, jest-config, jest-util, @jest/test-result, and jest-validate are all bumped to version 27.0.1 from previous iterations like 27.0.0 or pre-release "next" versions.
Developers upgrading from 27.0.0 should anticipate subtle enhancements and bug fixes within these core modules. This release ensures better compatibility and integration across Jest's ecosystem. The jest-util update from a next version to the stable 27.0.1 is particularly significant, indicating a finalized and tested utility set. Besides these dependency adjustments, the fundamental purpose of jest-cli remains consistent: facilitating test execution, configuration management, and result reporting within Jest projects. The published size differs slightly with a minor reduction in unpackedSize for the new release. Both versions maintain the same peer dependencies, development dependencies, license, and repository.
