There doesn't seem to be a good resource online describing the issues with protocol buffers and deterministic serialization (or lack thereof). This is a collection of links on the subject.

Protocol Buffers v3.0.0. release notes:

The deterministic serialization is, however, NOT canonical across languages; it is also unstable across different builds with schema changes due to unknown fields.

Maps documentation:

Wire format ordering and map iteration ordering of map values is undefined, so you cannot rely on your map items being in a particular order.
