+### High-level summary
+
+The last few weeks have seen us finialising a copule of things; notably our
+experiments into running Hydra with a custom ledger (to support, for example,
+    a custom plutus script operation you may be interested in). We have almost
+wrapped up incremental commits; just finishing the spec changes. We will then
+focus on a release, and some features that users have been wanting for a while
+around memory usage and resilience.
+
