+
+### `cardano-node` release: `10.0`
+
+We have been working on the `cardano-node-10.0` release.
+
+* [Removed versions older than NodeToNodeV_12][ouroboros-network#4985]
+* [Introduced NodeToNodeV_14][ouroboros-network#4986]
+
+### Tx-Submission
+
+We have been running an experimental build of `cardano-node` with new
+`tx-sumbission` logic [ouroboros-network#3311].  Some performance bottlenecks have been found by Karl
+Knutsson ([CF]), but not deadlocks or race conditions.
+* [Send TraceTxSubmissionProcessed for the new TX submission][ouroboros-network#4978]
+* [Let the thread which fetched a TX add it to the mempool][ouroboros-network#4984]
+
+### Preparations for removal of Non-P2P network code
+
+In order to prepare for removal of the network stack we addressed two issues:
+
+* expose `Mux` API for `node-to-client`s, so that they have more control over
+  how mini-protocols are running (e.g. implement ones own mini-protocol restart
+  policy) [ouroboros-network#3231], [ouroboros-network#4979]
+* reimplement `cardano-client` without using non-p2p network code (e.g. the
+  [subscribtion worker]), [ouroboros-network#4979]
+
+On the way we also addressed a few technical debt items:
+* removed `Network.Mux.Compat` interface: [ouroboros-network#4974]
+* [Clean-up Network.Mux.Channel][ouroboros-network#4336]
+* [Add bearer name][ouroboros-network#3472]
+
+### Documentation
+
+We updated the documentation of the peer-sharing mini-protocol:
+[ouroboros-network#4981], [ouroboros-network#4983].
+
+We updated the `SECURITY.md` file according to the IntersectMBO's
+Open-Source Committee guidance, [ouroboros-network#4986].
+
+### io-sim
+
+* [Distinct TVarIds for various TVar roles][io-sim#177]
+* Reviewed PRs contributed by Javier Sagredo ([IOG], Consensus Team):
+  * [Implement MonadLabelledMVar][io-sim#176]
+  * [Improve show of ScheduleMod][io-sim#175]
+  * [Attach label to TVars mentioned in Effects][io-sim#174]
+  * [Make takeMVar exception safe][io-sim#182]
