Expect version 26.4.0 represents a minor update to the popular assertion library used extensively within the Jest testing framework. Both versions, 26.3.0 and 26.4.0, serve the same core purpose: providing the expect function that forms the foundation for writing clear and expressive tests. Developers familiar with Jest will find the expect API unchanged in its fundamental usage.
The key distinction lies in the updated dependencies. Version 26.4.0 upgrades jest-matcher-utils from version 26.3.0 to 26.4.0. While the specific changes within jest-matcher-utils aren't detailed here, this update likely encompasses bug fixes, performance improvements, or potentially new utility functions relevant to custom matchers. For developers directly using jest-matcher-utils to extend expect with custom assertions, this update is the most pertinent. The update likely improves the overall functioning of the assertion of the library so users are encouraged to update to the newest version.
Both versions share identical dependencies and development dependencies, description, type of license, repository and size.
Given the similarities, upgrading from 26.3.0 to 26.4.0 should be a straightforward process with minimal risk of breaking changes, particularly if you're primarily using the standard expect matchers. The updated jest-matcher-utils could offer advantages for those developing custom Jest matchers, while all users will see a benefit to bug fixes and improvements.
