 ## [0.12.0] - 2025-11-11
 
 This release adds `KademliaEvent::PutRecordSuccess` & `KademliaEvent::AddProviderSuccess` events to Kademlia, allowing to track whether publishing a record or a provider was successfull. While `PutRecordSuccess` was present in the previous versions of litep2p, it was actually never emitted. Note that `AddProviderSuccess` and `QueryFailed` are also generated during automatic provider refresh, so those may be emitted for `QueryId`s not known to the client code.
