Version Details and Security Vulnerabilities

Tailwind CSS version 4.1.6 introduces several notable changes compared to the previous stable version, 4.1.5. Both versions remain committed to providing a utility-first CSS framework designed for rapid UI development, offering developers a streamlined approach to styling web applications. However, the newer version incorporates key updates that may influence a developer's decision to upgrade.

One significant enhancement in 4.1.6 involves the addition of specific development dependencies. Notably, magic-string and @ampproject/remapping appear as new dependencies, suggesting potential improvements or modifications in how Tailwind CSS handles source maps or string manipulation internally. These changes could translate to enhanced debugging capabilities or more efficient processing of CSS during development. The @tailwindcss/oxide dependency has also been updated to version 4.1.6 to keep perfect pace with the core package.

Another key difference lies in the unpacked size of the package. Version 4.1.6 occupies 674,922 bytes when unpacked, a slight increase compared to version 4.1.5's 658,207 bytes. While seemingly minor, this growth could reflect added features, optimizations, or even updated dependencies within the core framework. Finally, a key and important aspect of the package is the releaseDate indicating that both packages have been released in late April and the beginning of May 2025 signaling that, for the purpose of this exercise, we are talking about a package that will be released and the data is not indicative of the current status of the tool itself.
