Due to an unanticipated behavior of library updates that were done in the last release, we are rolling back some of the changes, alongside some significant bug fixes for the retrieval protocol which has resulted in a protocol logic change that has necessitated a protocol version bump as to prevent possible downturn of the mixed logic in the network. Node operators are requested to update to the latest version as soon as possible. Nodes which are not updated will not be able to retrieve data from the network.
