----------------------------------------
was (Author: ignitetcbot):
The available evidence describes a discovery/metastorage serialization
migration that may affect node interoperability; release-note impact requires
maintainer review.

> Following DTO implements {{Serializable}}:
> # {{DistributedMetaStorageJoiningNodeData}}
> # {{DistributedMetaStorageClusterNodeData}}
> They are transferred in {{DiscoveryDataBag}} ({{DiscoveryDataPacket}}) and
> should be transfromed to a {{Message}}.
> Some important tips:
> # Implementation of {{Serializable}} should be removed if possible. (If not
> stored somewhere in MetaStorage, or in PDS).
> # If it is difficult to transform to {{Message}}, message-clone DTO can be
> added, eg. {{QueryIndexMessage}}.
> # Keep in mind {{#writeObject}} / {{#readObject}} and {{#readExternal}} /
> {{#writeExternal}} methods, if any.
