+## Overview of [sprint 74][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][ouroboros-mithril] 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)
+
+* [`cardano-api`: **Added a new query for a snapshot of big ledger peers**][cardano-api#521]
+* [`cardano-cli`: **Query a node for a snapshot of big ledger peers**][cardano-cli#727]
+* [`cardano-node`: **Support for big ledger peer snapshot in the topology file**][cardano-node#5787]
+
+### 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.
