 ### Upcoming
 
 #### Highlights
- - 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 cluster management, plus future features.
-   - As an example, in your browser, you can enter the url: http://some_worker.local/unit_api/jobs/running to see a list of jobs running on a worker.

    - Note: there is no interactive user interface for workers, just an API
    - Previous actions that would involve SSHing from leader to a worker are replaced by web requests.
-   - 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/`.
 
 #### Bug fixes
  - fixed an issue where a calibrated OD reading would be mapped to max OD signal if it was too low.
@@ -16,6 +15,7 @@
  - 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.
  - `watchdog` is neutered. It used to try to "wake-up" a job, but this was flaky and causing more problems than it solved.
  - removed python library dependency `sh`
+ - 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/`.
 
 #### Enhancements
  - Better MQTT re-connection logic.
