Scrub all changes to Protobuf files since last release to verify that they have "Added in 1.4.0" comment for new fields. #487
Description
For example, this PR appears not to have such comments on new fields that it added: fee499a
It would be good to do something like this and go through every change to the .proto files since the last release to verify whether all new fields are marked as new in 1.4.0, if they are.
