+## High level summary
+
+The SRE team continues work on cardano environment improvements and general
+environment maintenance.
+
+Some notable recent changes, updates or improvements include:
+* Cardano explorer is being sunset and will soon be replaced by a new [Cardano
+  Foundation explorer](https://beta.explorer.cardano.org/)
+* IOG mainnet pools are now participating in propagation time reporting using
+  Cardano Foundation's [blockperf
+  tool](https://github.com/cardano-foundation/blockperf)
+* Cardano-parts node nixosConfigurations, node entrypoint and process-compose
+  node jobs now utilize [mithril](https://github.com/input-output-hk/mithril)
+  client automatically on preview and preprod networks for faster
+  synchronization of first start up. Mainnet mithril client use as well as
+  signer modules will be available soon.
