  - Workers now have a webserver on them. This is one of the largest architectural changes to Pioreactor, and lays the foundation for better plugin and calibration management, plus future features.
  - APIs that initiate a background task either return with the result, or return a task id that be be looked up at `/api/task_status/`.
  - previous actions that would involve SSHing from leader to a worker are replaced by web requests.
- - We no longer recommend the Raspberry Pi Zero (the original Zero, not the Zero 2.).
+ - We no longer recommend the Raspberry Pi Zero (the original Zero, not the Zero 2.) since supporting a web server + pioreactor functions is too much for a single core.
+ - Better MQTT re-connection logic.
