Version 28.1.0 introduces updates primarily focused on dependency alignment within the Jest ecosystem. Examining the dependencies reveals upgrades to @jest/expect-utils, jest-matcher-utils, jest-message-util, and jest-util all bumped to version 28.1.0. This suggests a coordinated release addressing potential bugs, performance improvements, and feature enhancements within these related utilities. The jest-get-type remains on version 28.0.2. Developers should note these dependency updates as they might impact the behavior of existing matchers or introduce new possibilities for assertion customization. The unpackedSize has slightly decreased from 142726 to 142630 bytes, indicating a minor optimization.
