+- Token deposits and withdraws: Allow full withdraw or full borrow repays
+  even when the oracle is stale (#646, #675)
+
+  Stale oracles are a problem for Mango because the risk engine can then no
+  longer safely determine if a user action is safe or not. Before, a stale oracle
+  would completely block interactions with an account until the oracle got
+  updated again.
+
+  This change allows some actions even while an oracle is stale:
+
+  - Users with deposits in a token with a stale oracle can now withdraw tokens
+    as long as their account health provided by tokens with non-stale oracles
+    remains positive.
+  - Users with borrows of a token with a stale oracle can now repay the borrows
+    (unless they were being liquidated at the time).
+
+  These actions can be used to unblock an account by removing the offending token
+  from its balance sheet.
+
+- Expiring delegate: Accounts can now have a short-term delegate (#663)
+
+  This might allow users to temporarily delegate to an in-memory key, so they
+  can trade without having to re-approve every transaction on their wallet.
+
+- Flash loan: Start allowing Mango instructions after flash_loan_end (#681)
+
+  Liquidators may be interested in performing actions in the same transaction
+  as a flash loan swap.
+
+- Flash loan swaps: The DAO can now charge a fee (#660)
+
+  The DAO can now configure a fee on flash loan based swaps. Previously flash
+  loans that did not use more than the user's deposits were free.
+
+- Stop loss: Respect net borrow limits and change low-health completion (#677)
+- Stop loss: Store helpful UI fields (#654, #667)
+- Stop loss: Fees are configured by-token instead of globally (#659)
+- Stop loss: Avoid expensive health cache for expired orders (#682)
+- Account creation: Add account_create_v2 instruction (#680)
+- Token register: Revamp API for simpler use from governance (#665)
+- Token register untrusted: Adjust default oracle staleness (#678)
+- Fix typo in name of admin_token_withdraw_fees instruction (#655)
