+
+### Main achievements
+
+In addition to ongoing general maintenance and support of cardano environments,
+some highlights of SRE achievements for this quarter include:
+
+* All IOE cardano-parts supported node environments, including preview,
+preprod, and mainnet were upgraded to cardano-node release `10.5.1`
+with various additional pre-release candidate versions tested.
+
+* Changes required for the new tracing system to become the default tracing
+system have been largely implemented in cardano-node, including various
+scripts, nixos services, and OCI container updates.  Similar changes supporting
+the new tracing system have been also implemented elsewhere, such as the
+[iohk-nix](https://github.com/input-output-hk/iohk-nix) configuration repo,
+[blockperf](https://github.com/cardano-foundation/blockperf) monitoring tool,
+and nixos based
+[cardano-parts](https://github.com/input-output-hk/cardano-parts) node cluster
+tooling stack, allowing for the upcoming cardano-node `10.6.x` release later
+this year to default to the new tracing system.
+
+* With the exception of a few canary machine deployments, all IOE testnet and
+mainnet cardano-node infrastructure are now running using the new tracing
+system.
+
+* Cardano-node release binaries have been cleaned up and OCI containers now
+include the snapshot-converter binary.
+
+* [Adawallet](https://github.com/input-output-hk/adawallet) and the
+[cardano-airgap](https://github.com/IntersectMBO/cardano-airgap) image were
+feature upgraded to be compatible with operations required for the Midnight
+Glacier Airdrop, including cardano-signer signing and native token UTxO
+handling.
+
+* The devx-ci cluster has been expanded to include Oakhost Darwin build capacity.
+
+Details for this and many other SRE work items can be found in the biweekly SRE
+reports.
