Jest 27.4.2 represents a minor update to the popular JavaScript testing framework, building upon the foundation laid by version 27.4.1. While the core description remains consistent – "Delightful JavaScript Testing" – indicating no fundamental shift in the library's purpose, subtle changes exist under the hood. The primary distinction lies in the version bumps of its core dependencies, notably jest-cli and @jest/core, both moving from 27.4.1 to 27.4.2. These updates likely include bug fixes, performance improvements, and potentially minor feature enhancements within the command-line interface and the core testing engine. Developers should consult the changelogs for jest-cli and @jest/core specifically to understand the precise nature of these changes.
Both versions maintain identical peer dependencies, requiring node-notifier within the ranges of ^8.0.1, ^9.0.0, or ^10.0.0. This suggests consistent compatibility with notification systems. The import-local dependency also remains unchanged at version ^3.0.2, indicating no alterations to local module resolution. The package structure remains consistent with both having the same file count of 6 and unpacked size of 4740, meaning the update is likely focused on internal improvements rather than large feature additions. Furthermore, the release dates confirm that 27.4.2 was published shortly after 27.4.1, which might suggest a quick fix or a small set of improvements addressing immediate concerns reported in the older version.
