@@ -27,6 +27,7 @@
 - changed: WalletConnect Connect button pinned to the bottom of Confirm Connection
 - fixed: A send whose funds are not spendable yet says so instead of reporting a network error
 - fixed: A swap retried after a failure fetches a fresh quote instead of failing with a "closed proxy" error
+- fixed: WalletConnect Bitcoin message signing returns a BIP-322 signature when the dapp requests `bip322`
 - fixed: Auto-login starting two competing accounts when both `YOLO_PASSWORD` and `YOLO_PIN` are set, and attempting a login when either is set to an empty string.
 - fixed: Auto-login never running on a device with no accounts, since the welcome carousel took priority over the login scene that owns it.
 - fixed: USDC.e shown as USDC in the Optimism Tarot staking pools
