Huge update to developer UX and accuracy of the cross-origin method. There's a new module called entity_iframe_resize which has 0 configuration and "Just Works" to do initial and post-load updating of frame sizes to match between domains. This method uses window.PostMessage and Event mutators in order to dynamically resize parent windows whenever child content changes size. This is a dramatic improvement over previous methods as far as sizing accuracy and window'ed content and now change shape and accurately communicate this with parent windows securely.
This release has support for secure cross domain iframe based requests as well as some general bug fixes. It largely hasn't changed in dev much in awhile so moving this to RC phase. Watch https://www.youtube.com/watch?v=1frtEY5vDyk&feature=youtu.be to see how the cross-domain capabilities can be applied.
Views integration for embed code and link as fields that can be added to any entity type (respects admin settings associated to what types and bundles can be used as an iframe)
API / Documentation updated to reflect views integration as well as flexibility added to iframe embed properties.
You'll probably need to clear your cache for the views integration to be picked up if you are doing a file replacement upgrade. If not, it'll just work when enabled.
