21.5.1

21.5.1

• New plugin architecture
• New database tables: od_reading_statistics, stirring_rates
• New pio commands: install-plugin, uninstall-plugins
• improvements to continous_cycle dosing automation.
• hardware based PWM available on pins 1 & 3.

v21.5.0

• IR LED now turns off between OD readings. This allows other LEDs to trigger and take readings.
• Removed leader jobs time_series_aggregating and log_aggregating
• logs table in database has more metadata
• New Kalman filter algorithm that includes an acceleration term
• New database table, kalman_filter_outputs, stores the output of the internal Kalman Filter.
• workers report back to leader additional system information including available memory and CPU usage.
• Added new temperature control and temperature automations for this app and to the UI.
• Added undervoltage alerts to logging
• Added initial version of a plugin system
• pio run-always for jobs not tied to an experiment (monitor, watchdog, etc.)
• faster database backup sync between Pioreactors
• Ability to measure your blank vials is available using the pio run od_blank, and in the UI under "Calibrate"
• Smarter algorithm for displaying time series in the UI
• Log table only shows the past 24 hours of events.

v21.3.18

21.3.18

• new dosing automation: continous_cycle. Designed for using the Pioreactor as an inline sensor.
• stirring can now be dynamically adjusted between OD readings, for improved mixing (and hence more oxygen transfer). See settings in UI.
• custom timezone support is added in config.ini
• download_experiment_data is now called export_experiment_data - this has been updated on the UI as well.
• unpausing stirring will return the rate to the previous value, not necessarily the default value.

21.3.3

21.3.3

• fix GPIO mappings
• fix keyboard interrupts in pump actions
• fix race conditions in MQTT disconnects
• fixed a bug where a job's state would change to lost when another job (of the same type) would try to start.
• in ADCReader, changed from windowed moving average to exp. moving average to be more sensitive to recent changes in signal.
• Growth rate calculating is a bit more robust to i) users pausing the job to inspect the vial, and ii) to changing the stirring speed.
• mDNS alias is now configurable via the config.ini, so users could have multiple clusters without domain aliases colliding in the DNS.
• fixed GPIO mappings for PWM Amplifiers
• inventory in config.ini is now called network.inventory
• ui.overview.rename in config.ini is now called ui.rename

21.2.4

21.2.4

• fixed reconnect issues when leader went offline and then online
• pausing dosing_control now pauses sub jobs dosing_automation
• renamed _algorithm to _automation everywhere.
• ADC measurements are now run at exact time intervals (previously there was some drift). The adc job now publishes metadata about it's recording times.
• Improved error handling in od_reading

21.2.3

21.2.3

• The logs table in the database now contains, by default, all the DEBUG and up logs
  from all Pioreactors. It also has a new column to denote the software source of the log. A separate topic is now set up for the logging in the UI.
• pioreactor.local is now the default URL of the PioreactorUI.
• on Pioreactor install, a seed experiment is created so users aren't dropped into a "blank" UI.
• pubsub.subscribe_and_callback can now filter retained messages.
• "algorithms" is now called "automations" throughout
• reduced the number of threads per job
• new topic for raw ADC measurements: pioreactor/<unit>/<experiment>/adc/<channel>
• improved MQTT QOS for important jobs

21.2.2

21.2.2

• pios sync is now pios upgrade.
• pio upgrade requires flags: --app and / or --ui to upgrade the PioreactorApp and PioreactorUI respectively.

21.2.1

21.2.1

• new SQL tables: led_events, led_algorithm_settings
• dosing_algorithm_settings has a new schema: a json blob to represent any editable settings.
• new pio command: pio run led_intensity, ex: pio run led_intensity --channel B intensity 50
• new pio command: pio update will update the software to the latest code on Github (later will be latest released version), and if possible, update the UI code as well.
• new library dependency DAC43608 that supports our LED driver.
• config.ini now has abstracted any RaspberryPi pins: we only refer to the PCB labels now in config.ini
• pio kill can accept multiple jobs, ex: pio kill stirring od_reading
