Jest 30.0.4 represents a subtle yet notable update in the popular JavaScript testing framework. While the core description remains consistent—"Delightful JavaScript Testing"—a closer look reveals key differences from version 30.0.3. Primarily, the dependencies jest-cli and @jest/core are bumped to version 30.0.4, potentially incorporating bug fixes, performance improvements, or new features within the command-line interface and core testing engine. @jest/types and import-local remain the same.
Developers should investigate the changelogs for jest-cli and @jest/core 30.0.4 to understand the precise nature of these updates. The peer dependency on node-notifier remains unchanged, suggesting no alterations regarding desktop notifications for test results.
Both versions retain the MIT license and point to the same GitHub repository, ensuring continued open-source access and community involvement. The dist object highlights identical file counts and unpacked sizes, indicating that code base size is the same for both versions, so the changes are under the hood.
Perhaps the most significant change developers will notice is the release date: Jest 30.0.4 was released on July 2nd, 2025, later than Jest 30.0.3, released on June 25th, 2025.This recent release suggests a focus on addressing issues identified in the earlier 30.0.3 version and incorporating the change in related @jest/core and jest-cli packages. For those seeking the latest enhancements and bug fixes, upgrading to Jest 30.0.4 is advisable.
