This patch-level release renames the int-io module to serial (but retains the now-deprecated int-io name for the time being), includes a key fix to the CYW43439 driver for the new Raspberry Pi Pico 2 W, and fixes to the parsing of a number of different kinds of numeric literal. It also removes the source code for unsupported Nordic Semiconductor microcontrollers. Note that due to yet-unresolved issues with the USB CDC driver on the RP2350 is it is highly recommended one use the serial console when uploading the CYW43439 firmware, CYW43439 driver, and zeptoIP to the Raspberry Pi Pico 2 W; this can be accessed within full_usb builds by calling serial::serial-console.
