Version Details and Security Vulnerabilities

Fs-extra is a powerful Node.js library extending the native fs module with essential file system operations, like recursive directory creation (mkdir -p), file copying (cp -r), and deletion (rm -rf). Versions 4.0.2 and 4.0.3 share the same core functionality and dependencies, building upon the established utilities for robust file system manipulation. Both versions rely on jsonfile for easy JSON file reading and writing, graceful-fs to handle file descriptor exhaustion errors gracefully, and universalify to provide a consistent asynchronous API.

The key difference between versions 4.0.2 and 4.0.3 appears to be a bug fix or minor update, as indicated by the release date difference. Version 4.0.3 was released on December 5, 2017, after version 4.0.2, which was released on September 12, 2017. For developers, upgrading to version 4.0.3 from 4.0.2 is likely a low-risk way to benefit from potential stability improvements and bug fixes. Both versions depend on the same set of devDependencies (klaw, mocha, rimraf..), confirming a similar testing and development environment as well. While the core functionality remains unchanged, the later release of 4.0.3 suggests an iterative improvement, underscoring the importance of staying current with minor version updates for stability and reliability in file system operations.
