Release Notes
6.0.16.1746: Nov 10 2017
PlasticProtocol (the super optimized protocol we are using as default since 6.0 and also supported by latest 5.0 and 5.4) is now capable of doing "retries".
What does it mean? You are sending a replication package to a remote server, connection is killed (you change network or whatever), Plastic will try to reconnect instead of just aborting the operation.
This has been supported in Remoting (the other protocol we have, which we want to deprecate soon) for years.
