Version Details and Security Vulnerabilities

Lint-staged is a popular npm package that streamlines the process of running linters on files staged in Git, ensuring code quality and consistency before commits. Version 12.1.1 improves subtly over version 12.1.0. The core functionalities remain the same: lint-staged leverages tools like ESLint, Prettier, and others, selectively applying them only to files that you're about to commit. This prevents unnecessary linting of the entire codebase, resulting in faster feedback loops and a cleaner Git history.

Both versions listed here share the same dependencies, including yaml, debug, execa, listr2, enquirer, and other widely-used packages for configuration, debugging, task management, and command-line interaction. The devDependencies for testing and development, such as jest, husky, and various ESLint plugins, are identical too.

The major differences are the release date and the unpacked size of the packages which could hint to internal code optimizations and bug fixes. Version 12.1.1 was released shortly after 12.1.0. Both versions have same file count that being 25. While both 12.1.0 and 12.1.1 are stable releases the latter might include certain improvements and bug fixes. Developers should always use the latest version to benefit from the most up-to-date features and improvements. Always asses depending on the urgency of the update.
