Welcome to Network Canvas 5.0.0

This release includes the following fixes and improvements:

  • Updated the core electron and node versions
  • Fixed an issue where the 'required' validation wasn't correctly working for empty strings
  • Enabled searching across multiple node properties in the large roster interface
  • Fixed skip logic and query building using ego rules. These rules should now operate correctly.
  • Fixed a bug where skip logic would act on a stale version of the network, and give incorrect outcomes.
  • Updated the full screen form setting to default to 'off' on all devices. The option can still be enabled if required.
  • Notarized the app, allowing it to be downloaded and installed on macOS Catalina (10.15.x)

Known Issues

  • Loading CSV formatted data performs poorly, particularly on mobile devices. This operation is CPU intensive, and causes devices to stall, sometimes for multiple seconds.
    • Strategies for mediation: Use alternative data formats, and/or minimise the size of external data files. Use more powerful devices. Use the Name Generator Roster (Large) interface, which performs slightly better.
    • Long term resolution: Parse external data when session starts (potentially to temporary storage), and stream it into memory on stage load.
  • The Name Generator Roster (Search) interface does not work well on devices with software keyboards.
    • Strategies for mediation: Use alternative platforms if this feature is important for your research.
    • Long term resolution: Adjust the styling to better work within the constraints of devices with limited vertical space.
  • Large protocols may cause the app to crash during import on iOS.
    • Strategies for mediation: Do not include large assets in protocols. Avoid using iOS if large assets are essential.
    • Long term resolution: Attempt to implement unzipping within a stream.

This app is part of a free, open-source suite of tools for the collection of social network data developed through the Complex Data Collective, a registered not-for-profit, and funded by the National Institutes of Health (R01 DA042711). Network Canvas is a collaboration between Northwestern University and the University of Oxford managed out of Northwestern’s Institute for Sexual and Gender Minority Health and Wellbeing.
