Version 4.4.0 of the Opentrons App and OT-2 Software is a release focused on stability and behind-the-scenes improvements to our software.

Technical change log

Opentrons App

This is a quiet release on the app front as we make some behind-the-scenes improvements to how the app is built, so we don't have any changes to report here.

OT-2 Software

New Features

  • Triggering a move_to to a labware will now count the labware as "used" in the protocol, allowing it to show up in the calibration list (#7812)
  • Various documentation and error message improvements

Bug Fixes

  • A new Protocol API version was added - 2.11 - to ensure that liquid handling commands like aspirate and dispense will rejected if the source or destination labware is a tip rack (thanks to @andeecode for reporting #7552!)
  • The robot's built-in HTTP server now sends the correct headers for CORS (thanks to Benedict Diederich for reporting #7599!)
  • Added guards to prevent resumptions from a delay overriding higher priority pauses (#7773)
  • Fixed several memory leaks in module handling that could lead to spurious error logs and other issues (#7641 and #7690)

Known Issues

In 4.4.0 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.
