Felgo QML Hot Reload Improvements
QML Hot Reload, as a standalone tool, has received many significant updates over the last few months. With Felgo 4.3.0, we also bring those improvements to the SDK.

Highlights of Qt 6.8 - What’s New?
Felgo 4.3.0 also updates the used Qt version from Qt 6.4.1 to Qt 6.8.3, providing access to all the latest features and improvements of this Qt LTS version.
One of the highlights of Qt 6.8 is the availability of the new FFMPEG QtMultimedia plugin. This provides a unified way to play audio, video, and camera content for your apps.
Note: You can still opt in to use the native Multimedia backend on specific platforms. Refer to the updated documentation for further information.

Qt 6.8 also adds new modules for Qt Graphs for 3D visualization, Qt Quick Effects, improved Qt Quick 3D, and better Qt Quick Controls desktop integration.
Migration Notes:
- Qt 6.8 updates the Windows MSVC compiler from 2019 to 2022. An updated kit is available in the Maintenance Tool.
- AppMap now uses the Qt QtLocation and QtPositioning modules. This changes the way how gestures work. AppMap now includes custom handlers for dragging, flicking, pinching and tapping the map, as well as support for the mouse wheel. To control which gestures are enabled, you can use the new properties pinchEnabled, wheelEnabled, dragEnabled and tapEnabled.
- Felgo projects no longer automatically link QtLocation and QtPositioning. Please refer to the AppMap documentation for instructions on linking modules if you use Maps in your application.
- The MapLibre maps plugin now uses updated plugin parameters.
- With the switch to Qt 6.8, Felgo now links against OpenSSL 3.x instead of OpenSSL 1.1.
Android 15 Support & Cloud Builds
This release updates Felgo to support the latest APIs and Google Play Store requirements for Android 15:
Felgo 4.5.0 uses the Gradle 8.10 plugin and builds against Android-35 by default. This allows apps to be built locally and via Felgo Cloud Builds for the recent Play Store requirements.
After updating the Felgo SDK, create a fresh Android build to use the latest plugins and frameworks in your project.
Felgo Cloud Builds also updates to Felgo 4.3.0 and Android 15. Make sure to migrate your project for Android and iOS according to the migration steps in the changelog!
Speaking of the latest Google Play Store requirements, we will bring an update to Felgo 4.3.1 soon, which includes a Qt 6.8.3 build that is compatible with the 16KB page size requirement that Google enforces beginning of November. In the Google Play Console, there is an option to extend the deadline to the 31st of May 2026. We strongly advise using that option so you have more time to migrate your apps.
Qt Creator 17 Update
Felgo now ships with Qt Creator 17.0.1, which has added many new features and improvements since the last update. Please refer to the official Qt Creator changelogs for more information.

More Features and Improvements
Felgo 4.3.0 includes many more improvements, for example:
- Allows for custom page transitions in a NavigationStack. Use a StackViewDelegate with the NavigationStack::transitionDelegate property.
- Fixes the AppPage::leftBarItem not working with Navigation in drawer mode.
- Fixes an empty NavigationItem::page property of Navigation::currentNavigationItem.
- Fixes the issue where setting Navigation::currentIndex is ignored when initially set.
- SimpleRow::badgeRadius now takes density-independent pixels into account; you may need to adapt your values in your projects with this change.
- and many more.
