Version Details and Security Vulnerabilities

Jest 30.1.0 represents a minor but potentially impactful update to the popular JavaScript testing framework, building upon the foundation laid by version 30.0.5. Both versions share the same core dependencies, including jest-cli, @jest/core, and @jest/types, ensuring a consistent experience for users reliant on Jest's core functionality. The import-local dependency also remains unchanged, suggesting that the way Jest handles local installations hasn't been altered. The peer dependency on node-notifier persists, indicating continued support for desktop notifications related to test runs, compatible across various versions.

The most noticeable difference lies in the version numbers of jest and jest-cli, as well as @jest/core. While @jest/types remains at version 30.0.5, the increment to 30.1.0 suggests bug fixes, minor enhancements, or potentially new features within the core testing framework and command-line interface. Developers should consult the official Jest changelog for detailed specifics on these changes. The releaseDate also changes to reflect the new version date: "2025-08-27T04:51:58.464Z" for version 30.1.0.

For developers, upgrading to Jest 30.1.0 is generally recommended, as minor version bumps often include important improvements and bug fixes that enhance the testing experience. However, it's still crucial to review the changelog for any breaking changes or migration steps, although these are unlikely given the minor version increment. The fileCount and unpackedSize remain consistent between the two versions, that means that no files were deleted or added between the 2 versions.
