The u-prefixed module aliases (ujson, ucollections, ubinascii, usocket, ustruct, ussl) are gone, and urequests is now just a shim over requests.
Follow badgeware's ci/micropython.sh pattern: pin MicroPython and pimoroni-pico, own the board definition in board/, cache the prepare and build steps. CI previously downloaded a prebuilt pimoroni-enviro .uf2 from pimoroni-pico releases, tying Enviro's MicroPython version to that repo's release cadence. board/ copies PICO_W_ENVIRO and micropython-enviro.cmake at the pinned SHA. dir2uf2 v0.1.0 reads the filesystem offset and size from the firmware's binary info instead of hardcoding them, and emits the filesystem-only and combined .uf2 in one pass.
Add ci/python.sh and ci/ruff.toml following the badgeware pattern, and fix the findings: mostly whitespace, quote style, redundant f-strings and comma imports. Substantive ones are 'is None' / 'not x' for '== None' / '== False', exception chaining on the wifi connect failures, and hasattr in config_defaults. Exclude enviro/mqttsimple.py as a vendored copy of umqtt.simple.
mkdir_safe compares against errno.EEXIST without importing errno, so the EEXIST path raised NameError instead of ignoring the existing directory - which is every reading after the first, once readings/ or uploads/ exists.
upload_readings iterated os.ilistdir("uploads") while os.remove'ing entries
from it, which can make littlefs skip or repeat entries mid-walk. os.listdir
reads the whole listing up front.
ssl.wrap_socket treats a str cert as a filename and only inline data as bytes, so passing the file's contents as a str made it try to open the PEM body as a path.
Reported version was still 0.0.10 three releases on. Closes #198.
DEVICES was a string, so ${DEVICES[0]} expanded to the whole list and the
unquoted -z test failed outright with more than one device attached. mpremote
also writes EEXIST to stderr, so the 'already exists' check never matched.
pimoroni-pico's modules_py/modules_py runs genversion.sh with the build dir as cwd, so git describe finds nothing and the frozen version.py comes out empty. Write it from the pinned checkouts in ci_genversion instead, matching badgeware.
phew dropped phew.ntp; the Pico MicroPython build freezes ntptime instead. Switch sync_clock_from_ntp to ntptime, raise its 1 second socket timeout to the 10 phew.ntp used, and set the pico RTC here rather than relying on phew.ntp.fetch() doing it as a side effect. Drop the stale note about provisioning pages failing to load after a reset - that was phew sharing one headers dict across every Response. Pinned to phew ci/picks, which carries mergeable upstream PRs on top of main; move to phew main once they land.

The name suggests it sets the C++ exception flags, but pico_cxx_options already sets all four by default and pico_runtime links it, so those are redundant. The -specs=nano.specs it adds to the link is the whole effect. Measured on enviro, against the 1200K region: with nano.specs 1165444 B 94.84% __verbose_terminate_handler 1181584 B 96.16% neither 1223764 B 99.59% 42KB of the 58KB is the C++ demangler, reachable only through libsupc++'s verbose terminate handler - overriding that handler is the conventional fix and recovers it without touching libc. The remaining 16KB is newlib-nano's smaller malloc and friends, which is an orthogonal decision. Ten pimoroni board module files include this, so it applies to all of them.
