   This would eventually lead to warning that says: "New inbound substream to PeerId exceeds inbound substream limit. No older substream waiting to be reused."
   See [PR 3152].
 
+- Refactor APIs to be streaming.
+  - Renamed `KademliaEvent::OutboundQueryCompleted` to `KademliaEvent::OutboundQueryProgressed`
+  - Instead of a single event `OutboundQueryCompleted`, there are now multiple events emitted, allowing the user to process them as they come in (via the new `OutboundQueryProgressed`).
+  - `get_providers` and `get_record` do not terminate automatically anymore, the caller needs to call `query.finish()`, on termination conditions.
+  - There is no more automatic caching of records, the user has to manually call `put_record_to` on the `QueryInfo::GetRecord.cache_candiates`.
+  See [PR 2712].
