Robot Stack Version 8.1.0

8.1.0 (2024-10-09)

Welcome to the v8.1.0 release of the Opentrons App!

There are no new features in the Opentrons App in v8.1.0, but it is required for updating the robot software to support the latest production version of Flex robots.

Bug Fixes

• Prevented Flex from showing the first-run screen when powering on a robot that's already set up.
  • • app: get back unboxingFlow path update function (#16411) (4bca02a)

Python Protocol API v2 - 2.20 Documentation

Welcome to the v8.0.0 release of the Opentrons App!

New Features

• Recover from errors during a protocol run on Flex. If certain types of errors occur, you will have the option to manually correct the error and resume your protocol. Follow detailed recovery instructions on the touchscreen or in the app.
• Perform quick transfers on Flex. Set up a new quick transfer directly on the touchscreen, specifying a tip rack and up to two labware for pipetting — no protocol file or coding required! You can save and reuse up to 20 quick transfers on a particular Flex robot.
• Use CSV files as runtime parameters. When setting up a protocol in the app, choose any file on your computer. Or on Flex, select from files already stored on the robot or on an attached USB drive. See the Python API documentation for more information on adding CSV capability to your protocols.

Improved Features

• Run protocols using the latest version of the Python API (2.20), which adds more partial tip pickup configurations (Flex and OT-2 GEN2 pipettes) and the ability to detect whether a well contains liquid (Flex pipettes only).
• Tap or click on any labware on the deck map to see adapters and modules that are stacked below it.
• Lists of liquids now separately show the total volume and per-well volume (when it is the same in each well containing that liquid).
• Improved instructions for what to do when a Flex protocol completes or is canceled with liquid-filled tips attached to the pipette.

Known Issues

• Stored labware offsets can't be applied to protocols that require selecting a CSV file as a runtime parameter value. Write the protocol in such a way that it passes analysis with or without the CSV file, or run Labware Position Check after confirming parameter values.
• Error recovery can't perform partial tip pickup, because it doesn't account for the pipette nozzle configuration of 8- and 96-channel pipettes. If a recovery step requires partial tip pickup, cancel the protocol instead.
• Downloading robot logs via USB may take up to 2 minutes on macOS, and may fail entirely on Windows. Use an Ethernet or Wi-Fi connection to download logs if needed.

Welcome to the v8.0.0 release of the Opentrons robot software!

New Features

• Create, store, and run quick transfers on Flex.
• Define and use CSV runtime parameters in Python protocols.
• Detect the presence or absence of liquid in a well (Flex pipettes only), and continue or pause the protocol based on the result.
• Automatically pause Flex protocol runs when detecting overpressure, allowing for error recovery and run resumption.

Improved Features

• Provides more partial tip pickup configurations. All multi-channel pipettes now support single and partial column pickup, and the Flex 96-channel pipette now supports row pickup.
• Improves homing behavior when a Flex protocol completes or is canceled with liquid-filled tips attached to the pipette.

Known Issues

• During single-tip or partial-column pickup with a multi-channel pipette, tips in adjacent columns may cling to empty nozzles. Pick up tips row by row, rather than column by column, to avoid this.
• Protocol analysis and opentrons_simulate do not raise an error when a protocol tries to detect liquid with a pipette nozzle configuration that doesn't contain a pressure sensor (single-tip pickup with A12 or H1). Avoid using the A12 and H1 nozzles for single-tip pickup if you need to detect liquid presence within wells.
• opentrons_simulate describes motion to wells only with respect to the primary channel, regardless of the current pipette nozzle configuration.
