+## High-level summary
+
+This week, the Hydra continued work on finishing mainnet compatibility. The
+semi-automated smoke tests and some missing documentation is still preventing
+from calling that fully done. They fixed smaller issues and made a step in the
+Head protocol more robust. Besides development, they met with interested people
+from the community who want to get started collaborating on communication and
+marketing materials.
