v4.0.0-rc.1

next-mdx-remote has been upgraded to use MDX v2 under the hood, which comes with improved performance and a whole list of other enhancements. Due to the improved code generated from MDX, we've also been able to remove our usage of esbuild. If you're using Next v12, no changes should be required to upgrade! Users on Next v11.1 might need to set experimental: { esmExternals: true } in next.config.js.

Note that some of the underlying changes in MDX v2 may require you to adjust some of your MDX content or custom components.

Take it for a spin and let us know if you run into any issues. 🙏

$ npm install next-mdx-remote@next
