Major Changes

• #​13049 2ed4bd9 Thanks @​florian-lefebvre! - Deprecates the integration

  Tailwind CSS now offers a Vite plugin which is the preferred way to use Tailwind 4 in Astro. Please uninstall @astrojs/tailwind and follow the Tailwind documentation for manual installation.

  This updated major version is only provided as a convenience for existing projects until they are able to migrate to the new plugin. It offers no additional functionality and is no longer recommended, but may continue to be used in your projects until it is removed entirely.
