The v4.0.0 release is on GitHub, and you can read the full release announcement that dives deep into everything new.
The documentation has been updated for v4, including an upgrade guide for going from v3 to v4. Start a new project by following the getting started docs or in the browser with Tailwind Play.
I noticed that the upgrade guide includes an upgrade tool that does the heavy lifting for you, such as migrating your configuration file to CSS and upgrading dependencies. ❤️
Congratulations to the Tailwind team and community, which have worked hard to get to this point!
