Version Details and Security Vulnerabilities

Jest 30.0.2 represents a minor update to the popular JavaScript testing framework, building upon the solid foundation of version 30.0.1. Both versions maintain the core promise of "Delightful JavaScript Testing" and share fundamental characteristics. They include identical dependencies for core functionalities like command-line interface (jest-cli), testing core (@jest/core), type definitions (@jest/types), and local package import handling (import-local). The peer dependencies, specifying compatible versions of node-notifier, also remain consistent. This ensures developers upgrading will likely avoid dependency conflicts. The licensing (MIT) and repository information also remain unchanged, preserving origin and open-source nature.

However, a key difference lies in the @jest/types dependency. While jest@30.0.1 specifies @jest/types@30.0.1, Jest 30.0.2 bumps to @jest/types@30.0.1, suggesting a potentially important if small fix or enhancement within the type definitions that might offer better type safety or improved developer experience. Furthermore, and very importantly, the releaseDate field signifies that version 30.0.2 was released on 2025-06-19, approximately 12 hours later than version 30.0.1 (2025-06-18). This temporal difference indicates bug fixes, performance improvements or minor feature additions incorporated in 30.0.2 that weren't present in 30.0.1. Developers should prioritize upgrading to Jest 30.0.2 to benefit from these latest improvements and fixes, enhancing overall testing reliability and efficiency. Finally, both versions have the same fileCount and unpackedSize in their dist details.
