+
+### Main achievements
+
+In addition to ongoing general maintenance and support of cardano environments,
+main SRE achievements for this quarter include:
+
+* All cardano release environments, including preview, preprod, mainnet legacy
+  and mainnet new clusters were upgraded through cardano-node releases of
+  8.7.3, 8.9.0 and finally into 8.9.1 by the end of March
+
+* All cardano pre-release environments, including sanchonet, private chain, and
+  shelley-qa clusters were upgraded through cardano-node releases of 8.7.3,
+  8.8.0-pre, 8.8.1-pre, 8.9.0 and finally into 8.9.1 by the end of March
+
+* Sanchonet and private chain environments were both re-spun once each during
+  this quarter to support new pre-release versions of cardano-node in the Conway era
+
+* Cardano-parts added a cardano-db-sync process-compose stack for each
+  environment
+
+* Cardano-parts added a cardano-node process-compose stack for each environment
+
+* Cardano-parts added enhancements for topology related nixos modules and
+  functions to accomodate new bootstrapPeer functionality, new topology
+  attributes and increased complexity network deployments.
+
+* Cardano-parts added support for mithril signers integrated with block
+  producers and a mithril-signer-verifier service for monitoring
+
+* Sanchonet, preview, preprod and mainnet IOG block producers are now signing
+  mithril certificates
+
+* Cardano-parts added support for mithril clients in nixos cardano-node systemd
+  service, process-compose job stacks and nix cardano-node entrypoint, all of
+  which also require any mithril snapshot to be signed by a trusted IOG pool
+  prior to use
+
+* Cardano-parts added ip integration tooling, so that similar to other deployer
+  tools like nixops, nixosConfigurations possess ip information which can be
+  used in module configuration
+
+* Cardano-db-sync snapshots server migration from legacy mainnet cluster to new
+  mainnet cluster with a rewrite of the snapshot service was completed
+
+* Cardano metadata server migration to Cardano Foundation was completed
+
+* BlockPerf, a cardano-node performance monitoring tool, was integrated into the
+  new mainnet cluster relays
+
+* Cardano-node bootstrapPeer functionality was added with node 8.9.x, requiring
+  effort to align nixos service module code between cardano-node nixos
+  services, iohk-nix topology generation, cardano-ops legacy code, and
+  cardano-parts module compatibility as well as feature test under various edge
+  cases
+
+* Cardano-playground added govtool backend support for private chain voltaire
+  testing team
+
+### Next steps
+
+* Add support for the new cardano-node metrics system
+
+* Add IPv6 cardano-parts support
+
+* Extend govtool frontend and backend to a process-compose stack
+
+* Adapt network spin-up tooling for the new create-testnet-data cardano-cli command
+
+* Continue cardano-parts and operations improvements
