 ### Minification
 
-You can opt-in to using the Next.js compiler for minification. This is 7x faster than Terser.
+Next.js' swc compiler is used for minification by default since v13. This is 7x faster than Terser.
+
+If Terser is still needed for any reason this can be configured.
 
 ```js
 // next.config.js
 
 module.exports = {
-  swcMinify: true,
+  swcMinify: false,
 }
 ```
 
-If you have feedback about `swcMinify`, please share it on the [feedback discussion](https://github.com/vercel/next.js/discussions/30237).
