+## High-level overview of [sprint 54][sprint-54]
+
+
+In this sprint, we merged the bootstrap peers (aka weak genesis) changes to
+the `ouroboros-network` repository ([ouroboros-network#4615]).  We continued
+working on integration & testing it using an early development version of
+`cardano-node` ([cardano-node#5485]).
+
+[Andrew Westberg] ([DripDropz]) noticed and fixed a mistake in the cddl spec which resulted in
+misleading documentation; [ouroboros-network#4790]. The Handshake protocol flag
+should be called `initiatorOnlyDiffusionMode`.  Library authors providing
+connectivity with other nodes via the `node-to-node` protocol are advised to review
+their implementation.
+
+We continued working on the `tx-submission` decision logic;
+[ouroboros-network#3311].
+
+[Karl Knutsson] ([CF]) implemented:
+
+* a debugging feature which dumps outbound governor state on the `SIGUSR1` event
+  (supported on *POSIX* compatible OSes); [ouroboros-network#4730], [ouroboros-network#4789].
+* limited the rate at which one can discover nodes through peer sharing;
+  [ouroboros-network#4778].
+
+## Open Source Contributions
+
+### IOSim
+
+We released a new version of [io-sim to Hackage][io-sim-1.4.0.0]:
+* [Sebastian Nagel] (IOG) fixed a bug in the `flushTQueue` implementation; [io-sim#135]
+* We fixed the underflow error in `threadDelay` in the `si-timers` library
+  ([io-sim#129]) reported by [Nick Frisby] (Tweag)
+
+### NoThunks
+
+We released a new version of [nothunks to Hackage][nothunks-0.2.0.0]:
+* `wherefrom` support; [nothunks#46]
+* added `Solo` instance; [nothunks#45]
+* added instances for `Monoid` and `Semigroup` newtype wrappers; [nothunks#43]
+
+## Low-level summary
+
+* We started using the `ImportQualifiedPost` extension, hence a large
+  (autogenerated) syntax change; [ouroboros-network#4715].
+* Code cleanup; [ouroboros-network#4792]
