We're going to change our preview URL for assets from *.amazonaws.com to preview-cdn.scrvt.com on Thursday, 2016-12-08 around 11:00 CET.Existing links will continue to work, meaning that the legacy URLs pointing to *.amazonaws.com won'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.
