Jest version 30.1.2 represents a minor update to the popular JavaScript testing framework, building upon the foundation laid by version 30.1.1. Both versions share the same core description: "Delightful JavaScript Testing," indicating a continued commitment to providing a positive developer experience. The dependency structure remains largely consistent, with both versions relying on jest-cli, @jest/core, @jest/types, and import-local. Notably, @jest/types remains at version 30.0.5 in both releases, suggesting that the type definitions haven't undergone modification between these versions. The peer dependencies specification for node-notifier also remains unchanged, allowing compatibility with a range of node-notifier versions.
A key difference lies in the version of jest-cli and @jest/core that jest depends on. Version 30.1.2 depends on jest-cli@30.1.2 and @jest/core@30.1.2 while version 30.1.1 depends on jest-cli@30.1.1 and @jest/core@30.1.1, indicating updates of these core packages between the two jest releases.
The crucial element distinguishing these versions is the releaseDate. Version 30.1.2 was released on "2025-09-01", while version 30.1.1 was released on "2025-08-27", confirming the latest release. For developers using Jest, upgrading to 30.1.2 likely incorporates bug fixes and incremental improvements within the Jest core and CLI. While the visible changes might seem subtle from a high level, checking the changelogs for jest-cli and @jest/core between these versions is highly recommended to understand the precise nature of the updates and any potential impact on testing workflows.
