v3.0.0

Compare Source

Tailwind CSS v4 is here and it's time to upgrade tailwind-merge to support it. tailwind-merge v3.0.0 is more accurate than ever and follows the Tailwind CSS spec more closely than in v2. That is thanks to Tailwind CSS v4 being more consistent than ever.

This release drops support for Tailwind CSS v3 and in turn adds support for Tailwind CSS v4. That means you should upgrade to Tailwind CSS v4 and tailwind-merge v3 together. All breaking changes are related to the Tailwind CSS v4 support.

Check out the migration guide and if you have any questions, feel free to create an issue.
