They fell victim to the same tooling slip that ate the cover subject: the v7 changelog sits at the very top of the cover body, above the title, instead of next to the older ones. Short version: patch 5 now stops the transmitter (MODE1 TxDisabl) instead of draining the FIFO, patch 8 gates the teardown before any wait and adds three race fixes from the v6 review bot, and patch 9 takes the port lock through the uart_port API and restarts a write deferred by the reconfigure gate as a fresh envelope. A v8, if one is needed, will have the cover in the usual shape. Sorry for the mess. Tapio
