Jest CLI version 27.2.5 is a minor update to the popular JavaScript testing framework, building upon the solid foundation of 27.2.4. Both versions aim to provide a delightful testing experience for developers, but the newer iteration includes key updates in its dependent packages. Core dependencies like @jest/core, @jest/types, jest-util, jest-config, @jest/test-result and @jest/test-utils have been bumped from version 27.2.4 to 27.2.5, suggesting potential bug fixes, performance improvements, or feature enhancements within these core modules. While the other dependencies like exit, chalk, yargs, prompts, graceful-fs, and import-local remain the same, the updates to the core modules are central.
Developers considering upgrading should specifically investigate the changelogs of @jest/core, @jest/types, jest-util, jest-config, @jest/test-result and @jest/test-utils to understand the precise nature of the changes, especially if they've encountered issues or require specific functionality addressed in the updates. Both versions support the same peer dependencies for node-notifier, providing consistent notification support. Although the unpacked size in 27.2.5 is slightly smaller, this difference is negligible. The newer version was released on October 8, 2021, offering developers the latest bug fixes and refinements that the Jest team addressed since the earlier 27.2.4 release on September 29, 2021.
