Version Details and Security Vulnerabilities

Eslint-plugin-jest is a valuable tool for developers using Jest, providing ESLint rules to ensure best practices and consistent code quality in their Jest tests. Version 22.1.3 introduces a key update in its development dependencies, specifically upgrading eslint-plugin-eslint-plugin from version 1.4.0 to version 2.0.0. This upgrade suggests improvements or new features in the tooling used to develop and maintain the ESLint plugin itself, potentially leading to more robust and reliable rules for developers leveraging the package. Other development dependencies like jest, husky, eslint, prettier and tooling for commit linting and staged file linting remain consistent between versions 22.1.2 and 22.1.3.

While the core functionality and peer dependencies (eslint: >=5) remain the same, the updated eslint-plugin-eslint-plugin likely reflects enhancements behind the scenes, potentially influencing the quality and accuracy of the linting rules applied to Jest test files. Developers who contribute back to the project might see more benefits from this tooling update. For developers primarily concerned with *using* the ESLint plugin, the practical impact of this specific dependency update in the short term may not be immediately apparent, but over time can result in even better reliability and accuracy for the plugin. The updated version was released on January 9, 2019 indicating continued maintenance and updates to the package.
