Version Details and Security Vulnerabilities

Jest Runtime version 30.0.4 represents a minor update over its predecessor, version 30.0.3. Key differences are primarily focused on internal dependency updates within the Jest ecosystem, aiming for improved consistency and potentially bug fixes. Notably, @jest/environment, @jest/fake-timers, @jest/globals, @jest/test-result, and @jest/transform have been bumped from version 30.0.2 or 30.0.3 to 30.0.4. jest-snapshot receives an upgrade from 30.0.3 to 30.0.4 as well. Whilst @jest/source-map was updated from 30.0.1 to 30.0.1 it remains unchanged in this latest version, developers using source maps should not be impacted. jest-haste-map, jest-message-util, jest-mock, and jest-util remain at version 30.0.2 and jest-regex-util and @jest/types remains at version 30.0.1. jest-environment-node was updated from version 30.0.2 to 30.0.4 accordingly with @jest/test-utils updating from 30.0.3 to 30.0.4. glob, chalk, slash, strip-bom, @types/node, graceful-fs and cjs-module-lexer as dependencies retain their previous versions. The package size remains identical at 91649 unpacked size and 6 in fileCount. The releaseDate shifted from June 25th, 2025 to July 2nd, 2025. Because of these internal dependecy updates, developers relying on specific behaviors or bug fixes within these core Jest modules might find upgrading to 30.0.4 beneficial. Otherwise, the changes might not necessitate an immediate upgrade for many users, unless they aim for the freshest and most stable point release across their Jest dependencies.
