TigerScale V3 v3.1.0

v3.1.0

The scale now tells you when an update is waiting instead of expecting you to go
looking. When it finds one it asks, once; if you say no it stays quiet for a day.

Added

• The scale checks for updates on its own — shortly after it joins WiFi, then
  every six hours — and asks whether you want to go to the update page. Answering
  No holds the question for 24 hours rather than raising it at the next check.
• A confirmation step before an update starts, with the one thing that matters on
  it: this takes about two minutes, and the power must stay on.
• A full-screen progress ring while the update is written, replacing the thin bar.
  It runs 0-100% once across both the web UI and the firmware instead of
  restarting between them, so the number always means "how far through".
• Six new interface strings, translated into all eight languages.

Fixed

• The update screen described the download and the installation as two phases.
  They are one: the firmware is written to flash as it arrives off the network,
  so the screen now says "Installation" for the whole operation and stops
  implying a wait that does not exist.
• Two comments in the source still claimed over-the-air firmware update was
  impossible on this board. That stopped being true in v3.0.0, when the partition
  table gained its second app slot.

Known issues

• The update prompt appears only from the idle weigh screen. If the scale is in
  the middle of reading a tag it waits, which in practice means the prompt can
  arrive a few seconds after the check that found it.

Updating

Over the air from Settings > Update, or over USB with
bash scripts/flash.sh --fs. Both keep your WiFi credentials, TigerTag session
and calibration.
