+## High level summary
+
+The SRE team continues work on Cardano environment improvements and general maintenance.
+
+Some notable recent changes, updates or improvements include:
+
+* All environments have been upgraded to cardano-node `9.2.0`.
+
+* All IOE run cardano-parts clusters (ie: sanchonet, preview, preprod, etc
+  testnets, mainnet and network-team clusters) have been upgraded to support
+  ipv4/ipv6 dual stack operations. This includes each cardano network's
+  respective public access or backbone DNS, now offering AAAA records for ipv6
+  connections.
+
+## Repository Work
+
+### Cardano-parts
+* Sets cardano-node to `9.2.0`. Adds ipv6 tf, module and recipe support for
+  ipv4/ipv6 dual stack operations. Updates alerts and dashboards for the new
+  tracing system to reflect metrics name changes and legacy metric prefix
+  normalization. Adds misc fixes and improvements. More detail is available in
+  the PR description:
+  [cardano-parts-pull-48](https://github.com/input-output-hk/cardano-parts/pull/48)
+
+### Cardano-playground
+* Deploys cardano-node to `9.2.0`. Converts all relevant cluster resources and
+  machines to ipv4/6 dual-stack operations. Updates alerts and dashboards for
+  the new tracing system to reflect metrics name changes and legacy metric
+  prefix normalization. More detail is available in the PR description:
+  [cardano-playground-pull-32](https://github.com/input-output-hk/cardano-playground/pull/32)
+
+### Cardano-mainnet
+* Deploys cardano-node to `9.2.0`. Converts all relevant cluster resources and
+  machines to ipv4/6 dual-stack operations. Adds new bootstrap scaling machine
+  startup and shutdown recipes. Updates alerts and dashboards for the new
+  tracing system to reflect metrics name changes and legacy metric prefix
+  normalization. More detail is available in the PR description:
+  [cardano-mainnet-pull-22](https://github.com/input-output-hk/cardano-mainnet/pull/22)
+
+### Ouroborous-network-ops
+* Deploys cardano-node to `9.2.0`. Converts all relevant cluster resources and
+  machines to ipv4/6 dual-stack operations. Updates alerts and dashboards for
+  the new tracing system to reflect metrics name changes and legacy metric
+  prefix normalization. More detail is available in the PR description:
