Expect version 30.1.2 represents a minor update over its predecessor, 30.1.1, within the Jest testing framework ecosystem. The key differentiators lie primarily in dependency updates. Version 30.1.2 upgrades @jest/expect-utils and jest-matcher-utils to version 30.1.2, while version 30.1.1 uses @jest/expect-utils with 30.1.1 and jest-matcher-utils with 30.1.1. @jest/test-utils also sees an update, moving to version 30.1.2 from 30.1.1.
These changes highlight a commitment to maintaining consistent versions and bug fixes within the related packages. Developers upgrading to 30.1.2 can expect potential improvements in matcher utilities and helper functions used for creating custom matchers. Given the scope of changes, any improvements would primarily revolve around internal workings that contribute to increased efficiency or improved stability of the ecosystem rather than any significant change in functionalities.
The release date difference of a few days suggests that these updates are likely related to addressing small issues or refining existing features. Both versions share the same core dependencies such as 'jest-mock', 'jest-util', '@jest/get-type' and 'jest-message-util', suggesting a focus on stability and incremental enhancements. Developers already using previous versions of the expect should find the transition to this version smooth with no expected breaking changes.
