Varios Proguard nuevas publican los servicios de Google Play v10.2.6 a v11.0.0 en un proyecto Multidex

He actualizado nuestra aplicación para utilizar la versión más reciente del Android Firebase SDK v11.0.0 ( https://firebase.google.com/support/release-notes/android#20170607 ) y de repente aparecen muchos nuevos errores proguard, FYI Todo estaba funcionando bien antes con proguard.

Antes de:

• ¿Por qué los métodos asíncronos llaman antes en Retrofit 2?
• OkHttpClient tiene un recuento máximo de reintentos
• Certificado de certificado okHTTP cuadrado - error sslSocketFactory
• Caché de datos de respuesta con retrofit2 + okhttp3
• ¿Cómo establezco el tiempo de espera para OkHttpClient?

compile 'com.google.firebase:firebase-messaging:10.2.6' compile 'com.google.android.gms:play-services-vision:10.2.6' 

Después:

 compile 'com.google.firebase:firebase-messaging:11.0.0' compile 'com.google.android.gms:play-services-vision:11.0.0' 

El problema es que no parece ser una simple nueva entrada de proguarda desaparecida, pero parece que se rompió todo, de repente varias otras bibliotecas parecían verse afectadas por este cambio.

Estos son los problemas de Proguard relacionados con el GMS:
