3.20.0

Robot Software and Opentrons App 3.20.0

v2.4.2

Patches two bugs in App:

1. Flask server correctly parses WellSeries containing WellSeries, so as not to duplicate containers in calibration
2. App-shell calls BrowserWindow.loadURL() within a setTimeout() to hopefully avoid trouble with Chromium not actually sending that request to Flask

v2.4.1

New Feature

Run with USB cable disconnected (requires latest v2.0.0 Smoothie firmware). If the "Run Job" button is pressed in the UI with a SHIFT-CLICK, the protocol will be converted to a .gcode file, then uploaded to the Smoothieboard to be run independent of any connected computer.

Bug Fix

To avoid any garbage data received during fast movements, driver.wait_for_arrival() will swallow any bad data.

Also adds more logging to app-shell to help determine why Windows users experience a white screen on app open.

2.4.0

• Support via Intercom
• User identitiy
• Motor driver to use latest Smoothie firmware
• In-app analytics
