Prism OnNavigatingTo no longer fires

We have been using Prism.Unity.Forms (version 7.1.0.431) with Xamarin.Forms for several months with good results. We currently tried to upgrade to (version 7.2.0.1367),which introduced a major change in behavior. It appears that the OnNavigatingTo event, which we use throughout out our app, no longer fires after the update. I was able to reproduce this behavior with a simple sample app. Is this a known bug/issue?

Short answer: yes. There were some breaking changes regarding Navigation in the latest Prim Release:

After numerous user survey's and interviews it became apparent that the intent of INavigatingAware had been become unclear and that users were actually overwhelmingly asking for a breaking change. INavigatingAware is no longer supported. For those who may be using OnNavigatingTo with INavigationAware this will be most impactful as a behavior change as INavigatingAware has been removed from INavigationAware meaning that it will no longer be called. For those who have implemented INavigatingAware directly you will see a build error. The impact should be minimal by simply renaming all instances of INavigatingAware to Initialize.
