+### Cardano-parts
+* Migrates to grafana alloy from grafana agent.  Drops deprecated
+  cardano-node service features and iohk-nix legacy mainnet relay filtering.
+  Fixes cardano-parts jobs for cardano-cli breaking change compatibility. More
+  detail is available in the release notes:
+  [cardano-parts-release-v2024-10-22](https://github.com/input-output-hk/cardano-parts/releases/tag/v2024-10-22)
+
+### Cardano-playground
+* Migrates to grafana alloy for metrics collection, rotates sanchonet kes,
+  fixes latest govtool develop nix packaging and nginx deployment and deploys
+  to sanchonet.  More detail is available in the PR description:
+  [cardano-playground-pull-34](https://github.com/input-output-hk/cardano-playground/pull/34)
+
+### Cardano-mainnet
