### Distributed Data
Configuration properties for controlling sizes of `Gossip` and `DeltaPropagation` messages in Distributed Data
have been reduced. Previous defaults sometimes resulted in messages exceeding max payload size for remote
actor messages.
The new configuration properties are:
```
akka.cluster.distributed-data.max-delta-elements = 500
akka.cluster.distributed-data.delta-crdt.max-delta-size = 50
```
