   - support for `prop:` directive to set the value of the containing node to the nativeView of the current node e.g `<gridLayout prop:mainContent>` for sideDrawer

 ### Changes
   - Refactored property name normalization to cache based on object prototype so we aren't walking all defined properties every time we get or set.
+  - Use the new 'scoped styles' boolean parameter when calling addCss if we don't detect any :global() styles. This should improve perf.
+  
 
 ## [0.5.3]
   - Add support for itemTemplateSelector closes [#86](https://github.com/halfnelson/svelte-native/issues/86)
