This release is the official introduction of zeptoIP, zeptoforth's IPv4 stack for the Raspberry Pi Pico W. Note that it is not included in any official binaries due to intellectual property reasons (specifically the non-free-ness of the CYW43439 firmware needed for the Raspberry Pi Pico W), but BUILDING_AND_USING_ZEPTOIP.md includes directions for building zeptoIP and its associated CYW43439 driver. The firmware is mirrored here.
