+
+### Main achievements
+
+In addition to ongoing general maintenance and support of cardano environments,
+some highlights of SRE achievements for this quarter include:
+
+* Cardano-parts started offering regular
+  [releases](https://github.com/input-output-hk/cardano-parts/releases) to ease
+  the process of upgrading rather than only PR merges with migration notes.
+
+* All IOE cardano-parts supported node environments, including preview,
+  preprod, sanchonet, mainnet were upgraded through various cardano-node releases
+  including `10.0.0-pre`, `10.1.0-pre`, `10.1.1`, `10.1.2`, and finally into
+  `10.1.3` by the end of December.
+
+* All environments were migrated from deprecated grafana agent to grafana alloy.
+
+* Sanchonet environment was re-spun twice; once for cardano-node
+  `10.0.0-pre` and once for a community scheduled PV11 hardfork test.
+
+* Preview and preprod networks were successfully forked into Conway era, Plomin
+  protocol version `10.0`.
+
+* Private and shelley-qa chains were retired after fulfilling their intended
+  goal.
+
+* Remaining cardano-world legacy resources were retired, replaced by
+  cardano-playground.
+
+Details of this and other SRE work can be found in the biweekly SRE reports.
+
+### Next steps
+
+* Switch to the new cardano-node tracing system as default and retire use of
+  the legacy tracing system, including dashboards, alerts, cardano-tracer and
+  cardano-node nixos service updates as well as container image required changes.
+
+* Continue cardano-parts and operations improvements.
