Jest 29.4.1 represents a minor update to the popular JavaScript testing framework, building upon the foundation established by version 29.4.0. While both versions share the same core description of "Delightful JavaScript Testing," and maintain identical dependencies on core Jest components like jest-cli, @jest/core, and @jest/types, as well as the import-local utility, developers should notice subtle but important improvements in the newer release.
Key highlights for developers considering the upgrade include an updated release date, with version 29.4.1 being published on January 26, 2023, after version 29.4.0 that was released on January 24, 2023. Both shared the same devDependencies for Typescript support using tsd-lite and @tsd/typescript, and same peerDependencies with node-notifier and same license terms under the MIT license. Similarly, the source code repository remains consistent between versions, hosted on GitHub under the Facebook organization.
In terms of differences at the package level, the dist object differs in the tarball link that reflects the new version. While boasting an equal number of files and unpacked size, indicating no significant additions or removals of code, these point releases usually include bug fixes and minor enhancements that improve stability, performance and overall developer experience, without introducing breaking changes. Developers are encouraged to review the changelog for detailed information of what was fixed in version 29.4.1 to determine if the update applies to their specific testing needs.
