+## [0.26.4] - 2026-09-28
+
+### Fixed
+- Bank transfer orders were never marked placed. `BankTransferPaymentDriver::pay()` had
+  dead code after an early `return` and never dispatched `PaymentDeferred`, so nothing
+  ever set `Order::placed_at` or fired `OrderPlaced` — no order confirmation email, no
+  stock decrement, the order missing from the customer's order history, and checkout
+  erroring out instead of showing the confirmation page. `pay()` now dispatches
+  `PaymentDeferred` the same way `CashOnDeliveryPaymentDriver::pay()` does.
+- `MarkOrderPlacedOnDeferredPayment` now skips
+  `OrderPaymentResolutionService::resolveDeferredPayment()` for a bank transfer order
+  (`OrderStatusFlow::isBankTransfer()`), so it correctly stays at `awaiting_payment` /
+  unpaid until staff mark it paid, instead of being advanced past that status the moment
+  checkout completes.
