ODK Collect v2026.1 Beta: real-time geo constraints, guidance hints shown by default, offline Entities from repeats

We are now targeting the first week of February for release. We have changed the release version to v2026.1 to reflect this change in timeline. There are still a few unknowns but we are getting close. Thanks to everyone for the great feedback.

ODK Collect v2026.1.0-beta.0 is now available :sparkles:

You can now try offline Entity updates and creation from repeat! You can use these sample forms:

This beta also provides partial support for continuous constraint evaluation for geotrace and geoshape. You can try it by adding incremental=true to the parameters column of a geotrace or geoshape question in XLSForm. You can also use this sample form to try out what we have so far.

There is still work to do on this functionality:

  • Once the constraint is violated, it will not be possible to add points until the violation is fixed
  • It will not be possible to save a trace/shape until there are no constraint violations
  • Invalid traces/shapes will be shown in red, valid traces/shapes will be shown in blue
  • Vertex markers will be increased in size so they can be moved more easily
  • More information on how to fix the issue will be available from the constraint error message
  • Dragging vertices in Mapbox will be fixed
