- Added POSIX desktop support for SDK builds, application packaging, and integration testing.
- Added POSIX filesystem partitions and improved application path handling.
- Added simulator support for loading and running applications dynamically.
- Improved simulator task stack handling and display startup reliability.
- Improved simulator display scaling, resizing, high-DPI support, and pointer accuracy.
- Fixed LVGL timers and input polling on POSIX. (fixes simulator with Linux on some Intel graphics platforms)
- Standardized data paths across platforms.
- Logging now works via separate task: this allows apps to write to log without it affecting their stdout (for apps that output text as relevant date for other apps, like the File Selection app)
- Fixes for app stdio
Implement file IO for applications to facilitate text input/output capturing.
Apps can now launch apps and:
- Read their stdio output
- Write to their stdio input
- Apps can specify task stack depth and preferred memory placement in their manifests.
- App identifiers are validated against length and character requirements.
- Crash diagnostics now show the crash cause, reason, fault address, call stack, and program-counter details, with logs saved for review.
- App closing is more consistent across built-in screens. There's now a dedicated function, and the old _emit() function is made private.
- Crash diagnostics no longer display a QR code without a call stack.
- Improved memory allocation for unrestricted requests.
Event handling:
- Added unified event handling for application, system, and Wi‑Fi events.
- Updated all apps to reflect event handling changes
Wi-Fi:
- Refactored event handling from listener interface to task & event group.
- Added direct Wi‑Fi radio controls and improved event subscriptions.
- Wi‑Fi screens now refresh asynchronously and handle unavailable devices more gracefully.
- Enabled Wi‑Fi by default on in dts files, but radio on/off is still done by code. The main reason was reliable event subscription and consistent devicetree states.
- Improved Wi‑Fi shutdown cleanup and radio-state handling.
Other:
- Renamed the Kernel Display app to Display.
- Auto-select widgets in Launcher and apps with toolbars on devices without touch.
- Improved USB HID input reliability, cleanup
- Updated PSRAM settings to improve boot stability on supported devices.
- Prevented duplicate Wi-Fi event subscriptions during screen rebuilds.
- Updated docs
- Fixes in WifiManage and WifiConnect
- Reduced main task stack size
- Moved USB HID stack size to PSRAM when available
- app_manager_find_manifest() now returns a copy instead of a pointer
