Expect versions 29.0.0 and 28.1.3, both exporting the expect function integral to Jest testing, showcase subtle but noteworthy differences for developers. Version 29.0.0, released on August 25, 2022, includes updated dependencies compared to version 28.1.3, which was released on July 13, 2022. Specifically, dependencies like jest-util, jest-get-type, jest-message-util, @jest/expect-utils, and jest-matcher-utils have been bumped to version 29.0.0 to align with the Jest ecosystem's latest advancements. In contrast, version 28.1.3 relies on earlier versions of these packages, such as jest-get-type at 28.0.2 and the others at 28.1.3.
While the core functionality remains consistent, developers upgrading to v29.0.0 benefit from the newest features, bug fixes, and performance improvements incorporated within the Jest ecosystem. The increased file count in v29.0.0's distribution (21 files versus 13 in v28.1.3) and slightly larger unpacked size (161208 bytes versus 142708 bytes) hint at internal enhancements or the addition of new functionalities within its dependency tree, although these are implementation details and don't reflect directly on the usage for external developers. For optimal compatibility and access to the cutting-edge testing experience, Jest users are encouraged to update to expect version 29.0.0.
