We're going to change our preview URL for assets from
preview-cdn.scrvt.com on Thursday, 2016-12-08 around 11:00 CET.
*.amazonaws.comwon't expire prematurely.
The change will be done automatically in our backend. No SDK upgrade is necessary.
If you are using your own CDN and have hardcoded the old preview URL in the
Scrivito::BinaryRewrite callback, you might need to adapt it.
