ArcGIS Enterprise 12.0 picks up new features from ArcGIS Experience Builder in ArcGIS Online June 2025 update. Key highlights include support for Arcade expressions, new GeoBIM widgets, and batch attribute editing. Additionally, the Emergency Response Guide (ERG) web tool offers the same functionality as the ERG widget in ArcGIS Web AppBuilder. For more information, check out the following blogs.

Does the Edit widget honor 24-hour time format now?

JoeHayes

This is great. One thing, can you add the ability to edit true curves to the Editor Widget. That would be super great! It's a real sticking point with our staff data contributors. Thanks!

Jianxia

@Joshua-Young, support for 24-hour time format is planned for Q1 2026 in ArcGIS Online and ArcGIS Enterprise 12.1 in May 2026.

For the "Save App State". When a user adds layers via "add data", will those layers be included in the new App State?

Jianxia

@TimDe_Muynck , When you add data on the fly, their state will be saved as well. Additionally, if you want to automatically display these runtime layers on the map in the next session, you should use the message action to add them to the map other than data action where users must manually click the Add to map button to see them on the map.
