Jest version 27.0.3 represents a minor update in the popular JavaScript testing framework, following closely on the heels of version 27.0.2. The core description remains consistent: "Delightful JavaScript Testing," underscoring Jest's commitment to providing a positive developer experience. The most immediate difference lies in the version numbers of the direct dependencies, with jest-cli and @jest/core both updated to ^27.0.3, aligning them with the primary Jest version. This suggests bug fixes, performance improvements, or new features within the command-line interface and core testing engine. The import-local dependency remains at ^3.0.2 indicating no required change for how Jest handles local installations for projects. The peer dependencies listed of node-notifier do not show changes.
The dist object reveals that both versions seemingly have similiar packed and unpacked sizes, and the same file count. One significant difference between the versions is the release dates. Version 27.0.3 was released on May 29, 2021, at 17:48:11.901Z, a few hours after version 27.0.2, released on the same day at 12:08:19.844Z. This points to a very rapid patch release, likely addressing a critical bug or issue discovered shortly after the initial 27.0.2 release. Developers should upgrade to 27.0.3 to ensure they are running the most stable and up-to-date version, benefiting from any fixes implemented in this quick patch. The update should be fairly seamless.
