This patch level release fixes an issue where transmission would sometimes halt with the USB CDC console (particularly when flushing the console), fixes pio::sm-addr! on the RP2040 (which previously did not actually work), and provides means to disable trapping of control-C and control-T on the U(S)ART and/or USB CDC consoles by setting uart-special-enabled and usb-special-enabled (which are set to true by default).
