A developer revived wasp-os, the MicroPython-based OS for the PineTime smartwatch, by porting it to mainline, up-to-date MicroPython instead of its old 2019 fork. The work required three pull requests merged upstream into MicroPython, targeted for version 1.30. Build tooling now uses uv, Bluetooth flashing uses bleak and dropped from over eight minutes to about three and a half, and free RAM at boot rose from 7.1 KB to 12.4 KB. New additions include a Dutch watch face, an 8-bit style clock, and a 'Guido' app showing a blocky portrait of Guido van Rossum with Python and MicroPython logos. The code is available on a GitHub fork branch.
