Version 4.5.0 of the Opentrons App and OT-2 Software is focused on quality-of-life improvements and fixes.

Technical change log

Opentrons App

New Features

  • Protocol uploads have been made substantially faster! (See OT-2 section below for more details.)

Bug Fixes

  • Fixed issues with the run timer reading 00:00 in the middle of a paused protocol (#7740)

OT-2 Software

New Features

  • The OT-2 now uses a faster analysis method on protocol upload
    • Thanks to everyone who beta tested this feature over the last few months!
    • You may revert to the old analysis method with the Use Older Protocol Analysis Method in your OT-2's advanced settings
    • If you encounter any issues (e.g. protocol run errors not caught during upload) please reach out to Opentrons Support or open an issue in GitHub so we can continue to improve this feature

Bug Fixes

  • Fixed a regression that prevented use of OT-2 Modules in Jupyter notebook (#8009)
  • Fixed an uncaught import error on macOS and Windows (#8154, thanks to Maksim Rakitin for the fix!)
  • Fixed a crash caused by invalid calibration data (#7962)

Known Issues

In 4.5.0 and previous releases, the OT-2 will only use TLS 1.0 for WPA2 Enterprise association. Some RADIUS servers have disabled this version of TLS; it must be enabled to connect the OT-2 to a RADIUS-secured network.
