+## Overview of [sprint 85][sprint-85]
+
+### High-level overview
+
+#### Node Diversity Workshop
+
+  We participated in the Node Diversity workshop held in Paris by Tweag / Modus
+  Create.  We had a chance to talk with [amaru] and [goroboros] developers.
+
+  We were in particular interested in testing approach for the [amaru] node,
+  which is described in a recent [series of blog posts][stavena].
+
+#### Tx-Submission
+
+We continued working on `tx-submission`.  We're analysing a test failure which prevents us from merging the PR.
+
+#### Mithril
+
+Armando Santos (Well-Typed) open a draft PR in which he's been working on
+implementation of the DMQ Node, see [ouroboros-network#5109]. Armando also
+wrote an update to the [CIP#137] proposal.
+
+#### Performance Imrpovements
+
+* We are reviewing [PR][ouroboros-network#5104] with inbound governor
+  performance improvements.
