Version 8.21.0 of @typescript-eslint/eslint-plugin brings incremental improvements over the previous stable release, 8.20.0. The core functionalities remain consistent, focusing on providing ESLint rules specifically designed for TypeScript codebases. The primary distinction lies in the updated dependencies, particularly within the @typescript-eslint ecosystem. Dependencies like @typescript-eslint/utils, @typescript-eslint/type-utils, @typescript-eslint/visitor-keys, and @typescript-eslint/scope-manager have all been bumped from version 8.20.0 to 8.21.0. Similarly, the development dependencies @typescript-eslint/rule-tester and @typescript-eslint/rule-schema-to-typescript-types also saw version updates.
These updates usually signify bug fixes, performance enhancements, and potentially new features within those specific utility packages, enhancing the reliability and capabilities of the core ESLint plugin. Developers should note these updates, as they might indirectly influence the behavior of certain linting rules or their interaction with the TypeScript compiler. Package maintainers benefit from the newest features and bugfixes, ensuring smoother workflows and a better tooling experience. The peer dependencies remain the same, indicating no breaking changes in terms of supported ESLint or TypeScript versions, allowing a seamless upgrade from previous versions. Considering the small difference in unpacked size, it's reasonable to assume that most of the changes are located within the updated dependencies.
