   @hanm Yes, the forward and backward compatible are being handled properly based on the
following 2 scenarios during upgrading/downgrading:
   
   1. Leader old, follower new, read digest will throw EOF but being caught and ignored
   2. Leader new, follower old, the extra digest fields are not being read, which doesn't
matter
   
   We also have tests covered these cases.
