High level overview​

This week, the Mithril team released the new distribution 2445.0. This distribution offers stable support for Cardano node v.10.1, the Cardano stake distribution client library, CLI and WASM, and the aggregator's Prometheus endpoint. It also includes bug fixes and performance improvements.

The team also continued implementing the new status route in the aggregator. Additionally, they reorganized the user manual section of the documentation website and started working on the new version of the Protocol Insights dashboard.

Finally, they implemented a new command in the aggregator CLI to generate genesis keypairs and refactored the signer and aggregator's store pruning implementations.

Overview of sprint 74​

Dropping NonP2P network stack​

We are advertising that we will drop the non-p2p network stack. This will happen after the next hard fork. Please comment on the PR if this will be problematic for you. Here's the PR: ouroboros-network#5007.

Node-to-Client versions​

We dropped node-to-client versions earlier than version 16, ouroboros-network#5002.

Mithril Design​

We completed review how to adopt ouroboros-network for Mithril design. We started to experiment with ouroboros-network in that direction.

Next Cardano-Node release​

The next cardano-node release will include the following changes from the networking team:

Typed-Protocols​

The integration of ouroboros-network-0.18, which is using the new typed-protocols-0.3 with ouroboros-consensus, was merged, ouroboros-consensus#1223. Integration with cardano-cli and cardano-api was rebased and handed to the release engineer. Integration with ekg-forward was merged: ekg-forward#35.

Genesis​

The following changes to support Genesis (both creating big ledger peer snapshots & providing them in a topology file)

Connection Manager​

We merged the documentation review of the connection manager, ouroboros-network#5001. We also renamed connection manager methods (as suggested by Neil Davies ([PNSOL])): ouroboros-network#5000.

Outbound Governor​

We started to experiment with using FRP to implement the outbound governor in a way that is both easier to maintain and reason about.
