 * Move `<script>` tags to end of <body> to enable 'loading' UI to be inserted into the boilerplate #6375
 
-* Includes fix for apps on Galaxy that use a CDN. The fix ensures the CDN won't cache broken js/css resources during an app upgrade.
+* Adds WebAppInternals.setBundledJsCssUrlRewriteHook allowing apps to supply a hook function that can create a dynamic bundledJsCssPrefix at runtime. This is useful if you're using a CDN by giving you a way to ensure the CDN won't cache broken js/css resources during an app upgrade.
