Version Details and Security Vulnerabilities

Tailwind CSS saw a minor version bump from 3.1.0 to 3.1.1 on June 9th, 2022, within hours of each other, indicating the second version was probably a hotfix. Both versions maintain the same core dependencies, peer dependencies, and development dependencies. This means the underlying PostCSS engine, build tools like esbuild and SWC, linting and formatting tools such as ESLint and Prettier, and testing frameworks like Jest remain consistent between the two releases. Developers can expect no breaking changes in these areas when upgrading.

The core functionality and utilities offered by Tailwind CSS remain unchanged, meaning the developer experience related to building user interfaces should be identical. The descriptions of the packages are also identical, which means that both versions include the same utility-first CSS framework for rapidly building custom user interfaces.

The only observable differences lie in the dist object, specifically the unpackedSize. Tailwind CSS 3.1.1 has a slightly larger unpacked size (4353655 bytes) compared to 3.1.0 (4351805 bytes). Also, the release date has a difference of around 11 hours. This suggests that version 3.1.1 likely contains minor bug fixes, performance improvements, or documentation updates that contribute to the small size difference, without altering the API or introducing new features. For developers, upgrading from 3.1.0 to 3.1.1 is recommended but not strictly necessary unless they are experiencing specific issues addressed by the hotfix. They can expect a smooth and seamless transition.
