3.3.0

• The Status page has a Water tank entry. The pod reports its tank sensor on
  every status read, and that reading only ever showed on the temperature page
  while the tank was low. A low tank now counts as needing attention, which
  also lights the dot on the Status tab, and the entry shows when the tank went
  low. A change has to hold for about 30 seconds before it counts, so water
  moving during priming does not register.

• Raw sensor recordings are kept for 14 days instead of 36 hours, and Settings
  can set anywhere from 2 days to 2 months. The recordings take about 0.4 GB a
  day. If the data partition drops below 2 GB free, the oldest recordings are
  removed first.

• The server and the biometrics stream now run with memory limits, and their
  processes are the first the system stops if memory runs out. The pod's
  heating and cooling firmware shares about 1.9 GB of memory with them, so a
  runaway analysis job should not be able to take memory it needs. The limits
  are installed by this update and apply from the next time each service
  starts. Reverting to stock removes them.

• Settings no longer links to community chat or donation pages. Nightstand is
  maintained independently of the projects it builds on; for help, open an
  issue on this repository.

• The guides were checked against the current code and corrected where they
  had drifted, most of all the API reference.
