+## Upgrade notes
+
+### v2.0.0
+
+The underlying tool used to generate placeholders has switched from JIMP to Sharp.
+This allows the plugin to handle a greater variety of image formats, while also increasing in speed.
+
+The API remains largely the same so most sites should not need to adjust their config.
+
+- The default values for `maxPlaceholderWidth` and `maxPlaceholderHeight` have been increased from 12 to 25 - this increases the quality of the LQIP without a significant change in filesize
+- `placeholderQuality` has been removed - at the size of the LQIP it didn't make much of a difference to filesize or image quality
+- The default value for `preferNativeLazyLoad` is now `false` - most users install this plugin to generate LQIP and the previous default meant the LQIP weren't visible in modern browsers
