Jest Environment JSDOM version 30.0.1 is a minor release following version 30.0.0 in the Jest testing framework's JSDOM environment adapter. Both versions maintain the core dependencies that provide the JSDOM environment for running Jest tests within a simulated browser environment. Key dependencies remain consistent, including jsdom for browser emulation, @types/node and @types/jsdom for TypeScript support ensuring compatibility with Node.js and JSDOM's APIs, as well as internal Jest packages like @jest/environment and @jest/environment-jsdom-abstract crucial for the JSDOM environment's functionality. The canvas peer dependency is still present, indicating continued support for environments utilizing Canvas APIs.
The primary difference lies in the release dates, with version 30.0.1 being released on June 18, 2025, a week after version 30.0.0, released on June 10, 2025. From a developer perspective, while the dependency list appears identical, this minor version bump from 30.0.0 to 30.0.1 likely addresses bug fixes, minor improvements, or security patches within the JSDOM environment. Developers upgrading should anticipate increased stability and potentially some performance gains. Crucially, because it's a patch release, no breaking changes are expected. Always consult the official Jest changelog for comprehensive release notes detailing the specific changes incorporated in version 30.0.1 to fully understand its impact on existing test suites.
