+- The `presets` feature had unexpected behavior where a preset config without its own `presets` key would not extend the default config. ([#2662](https://github.com/tailwindlabs/tailwindcss/pull/2662))
+
+  If you were depending on this unexpected behavior, just add `presets: []` to your own preset to exclude the default configuration.
