22.6.0

22.6.0

• You can now edit the config.ini without having to boot a Pioreactor. By adding a file called config.ini to the boot folder when the SD card is interested in a computer, the /boot/config.ini will be merged with the Pioreactor's config.ini. This is useful for changing settings before ever starting up your Pioreactor for the first time. See below.
• config.ini is now the place where the local-access-point's SSID and passphrase are stored.
• new pio command on leader: pio discover-workers returns a list of workers on the network (may be a superset of inventory in the config.ini)
• new pios command on leader: pios reboot. Reboots all active workers in the cluster.
• self-test tests run in parallel
• Adding NOTICE log level, which will appear in the UI.
• New schemas for kalman_filter_outputs and od_blanks tables in the db.

22.4.3

22.4.3

• table led_events is renamed to led_change_events
• automation events returned from execute are published to MQTT under the published setting latest_event
• new tables led_automation_events, dosing_automation_events, temperature_automation_events
• pioreactor.automation.events.Event renamed to pioreactor.automation.events.AutomationEvent. The have a second kwarg that accepts a dict of data (must be json-serializable).
• new leader command pios reboot: reboot RPis on the network, optionally specific ones with --unit flag.
• new CLI tool: pio log -m <message> which will post a message to the pioreactors logs (everywhere). Example: this is used internally after systemd finish to log to our system.

22.4.2

22.4.2

• Added ability to add callbacks to ODReader. See add_pre_read_callback and add_post_read_callback.
• Fix bug associated with user changes.
• pio logs no longer uses MQTT. Also, it now prints their entire log file.
• BETA: testing shipping with access-point capabilities. See docs.

22.4.1

22.4.1

• Fix bug associated with user changes.

22.4.0

22.4.0

• store more experiment metadata, like strain and media, in the database.
• adding temporary labels of Pioreactors into the database in pioreactor_unit_labels table
• renaming some tables, alt_media_fraction -> alt_media_fractions, ir_led_intensity -> ir_led_intensities
• pumps now throw a CalibrationError exception if their calibration is not defined.
• default user is no longer pi. It is now pioreactor. Any coded paths like /home/pi/ should be updated to home/pioreactor/.
• new image metadata file added to home/pioreactor/.pioreactor/.image_metadata

22.3.0

22.3.0

• fixed memory leak in MQTT connections
• better clean up after a job disconnects
• If the temperature of the heating PCB gets too high, the automation switches to Silent (previously it did not switch at all.)
• "datatype" field in published_settings is now used to cast before being given to set_* methods.
• Internally, the repo uses the msgspec library for complex MQTT message validation. This also introduces the pioreactor.structs module which details the structure of the messages.
• Name change: DosingAutomation -> DosingAutomationJob, TemperatureAutomation -> TemperatureAutomationJob, LEDAutomation -> LEDAutomationJob.
• New json-encoded datatype for changing automations over MQTT: see pioreactor.struct.Automation
• pio run led_intensity has new API: use the flags, ex: --A 10.0, to set the intensities on different channels.
• pioreactor.actions.led_intensity has a new API that accepts the desired state as a dict.
• pump actions are now under pioreactor.actions.pump instead of their own files.

22.2.0

22.2.0

• Added more error codes for the ADC, network issues, and high temperature
• Reduce chance of running multiple growth_rate_calculating jobs
• Custom exceptions thrown in the Python software.
• New checks for HAT being present, and Heating PCB being present, before a job is run (if required in the job).
• QOL improvements to stirring calibration
• Calibrations now store the data locally, alongside the calibration results, in the local storage.
• New API in DosingController to add custom pumps
• Some job_names are disallowed to avoid MQTT conflicts
• ADCReader now will estimate the local AC hertz to get a better OD reading signal.
• Custom Python exceptions were introduced.
• pioreactor.hardware_mappings is renamed to pioreactor.hardware
• New is_HAT_present and is_heating_pcb_present functions
• ErrorCodes is gone - use global variables in error_codes
• Adding logic for 180° sensor to growth_rate_calculating
• Pumps now have a state broadcast to MQTT, and thus can be "disconnected" over MQTT.
• Improved the response time of stopping pumps from the web UI.

22.1.0

• improved temperature-recording frequency (10m to 4m)
• removed the PWM's DC maximum on the heating output.
• New pioreactor.version.hardware_verion which reads from the HAT's EEPROM which version
  of board is being used.
• removed PD channels 3 & 4.
• angle column in od_readings_raw table in database is now an integer.

21.12.1

• Regression based temperature inference by @CamDavidsonPilon in #219
• Test out better handling of SSH disconnects by @CamDavidsonPilon in #223
• Hardware version by @CamDavidsonPilon in #226

Full Changelog: 21.12.0...21.12.1

21.12.0

21.12.0

• pid_stable automation renamed to stable
• jobs can now publish to pioreactor/<unit>/+/monitor/flicker_led_with_error_code/<error code>
  to have the LED flash a specific error code.
• fixed errors raised when not able to connect to leader's MQTT
• improvements to error handling in monitor job.
• replaced turn_off_leds_temporarily with the more useful and more general change_leds_intensities_temporarily
• UX improvements to the pump_calibration action
• improving *-Controller jobs:
  • automation is now a dict attribute (json in MQTT)
  • automation_name is a new published_setting, with string. This is what is read from the UI.
  • CLI has a slightly changed API to pick the automation
• pio_jobs_running renamed to pio_processes_running
