The next release of ArcGIS AppStudio is version 5.0, and as always, the AppStudio team wants to make sure this is a stable and quality release for our users. This release includes some major underlying changes to AppStudio, the most significant is support for Qt 5.15 and ArcGIS Runtime SDK for Qt 100.10, including the new and better Qt toolkit for the ArcGIS Runtime SDK. There is a possibility that this update will introduce breaking changes for your current AppStudio apps.
We have released an early (beta) version of AppStudio 5.0 on the Esri Early Adopter Community website (EAC). We ask that you test your current AppStudio apps with the beta version of 5.0 so the development team can identify and address any issues you find. Please, let us know what you encounter by submitting an issue on the EAC website.
