 # Overview
 
  ### Team Wins 🎉
- - Successfully tested EFM recovery on testnet
-
+ * Successfully tested EFM recovery on testnet
+ * Completed new TPS loader and run manual test, confirming no performance regression since pre-Crescendo (Sep 3rd).
+ * Completed [Atree refactor to remove technical debt](https://github.com/onflow/atree/issues/464).
+ * Complete work on Bader -> Pebble DB for [Chunk Data pack Pruner](https://github.com/onflow/flow-go/issues/6516).
