Compaction is now treated as an implementation detail of Storage implementations; Node.Compact() and related functionality have been removed. Ready.Snapshot is now used only for incoming snapshots. A return value has been added to ApplyConfChange to allow applications to track the node information that must be stored in the snapshot. raftpb.Snapshot has been split into Snapshot and SnapshotMetadata, to allow the full snapshot data to be read from disk only when needed. raft.Storage has new methods Snapshot, ApplySnapshot, HardState, and SetHardState. The Snapshot and HardState parameters have been removed from RestartNode() and will now be loaded from Storage instead. The only remaining difference between StartNode and RestartNode is that the former bootstraps an initial list of Peers.
