+Adds a new, optional `kernel` configuration option to select a resize algorithm in the Sharp image service
+
+By default, Sharp resizes images with the `lanczos3` kernel. This new config option allows you to set the default resizing algorithm to any resizing option supported by [Sharp](https://sharp.pixelplumbing.com/api-resize/#resize) (e.g. `linear`, `mks2021`).
+
+Kernel selection can produce quite noticeable differences depending on various characteristics of the source image - especially drawn art - so changing the kernel gives you more control over the appearance of images on your site:
+
+```js
+export default defineConfig({
+  image: {
+    service: {
+      entrypoint: 'astro/assets/services/sharp',
+      config: {
+        kernel: "mks2021"
+      }
+  }
+})
+```
+
+This selection will apply to all images on your site, and is not yet configurable on a per-image basis. For more information, see [Sharps documentation on resizing images](https://sharp.pixelplumbing.com/api-resize/#resize).
