Please read the upgrade guide for Tailwindcss before upgrading to this version of the NYCO Patterns. While most things are the same some utility selectors may have updated from v1 to v2.
All of the core plugins of Tailwindcss are included in this distribution and it is highly recommended, if not required, for you to install and configure PurgeCSS in your project to remove unused utilities. More about optimizing the Tailwindcss build for production can be read about in this guide.
