- External apps can opt into automatic cleanup when they exit, including tracked tasks, threads, files, directories, and memory.
- App-relative file paths resolve against the app’s working directory, with `.` and `..` normalized.
- The shell identifies ELF binaries that cannot be executed instead of treating them as scripts.
- Shared icon fonts now offer distinct default and large sizes, with updated icons across the interface.
- ESP32 apps can load additional ELF formats when address mirroring is enabled.
- Terminal colors render clearly on monochrome displays, and toolbar buttons have cleaner styling.
- GPS settings safely refresh their device list when their window is hidden or its widgets are destroyed.
**Fonts**
Dynamically load text and icon fonts when the device boots.
Font bitdepth depends on whether the device is an ESP32 one and whether it has external RAM available.
When no external RAM is available on ESP32, only small and medium font variants are generated; large font variants refer to the medium size ones.
Implemented Appearance settings app for changing font and font size.
**Other changes**
- Added keyboard shortcuts to delete or rename files in directory views.
- Improved app-grid tile sizing to provide more room for labels.
- Reduced the default LED strip brightness.
Graphics & rendering
- Implement `binfont-module` to generate bitmap fonts on the device itself
- Remove lodepng support from LVGL library and create `Modules/lodepng-module` to make the feature re-usable in non-LVGL apps too. Add binding functions for LVGL support.
- Implement large icons for boot screen (Tactility and USB logos)
- Remove unused asset files in `Data/`
Boot
- Split up `Tactility.cpp` and its `run()` function into various `Init*.cpp` files.
- Re-implement `Boot.cpp` app as non-LVGL app
- Boot app now has a `BootSequence.cpp` for the init code.
- LVGL is now started when the Boot app finishes
- Move more init logic into Boot app
BLE
- Don't allocate scan result buffers unless BLE is on
- Allocate scan results in external memory if possible
UX & UI
- USB Settings app: remove border from the button container
- Implement double size icon assets in `lvgl-module`
- `AppList` and `Settings` app now show a paginated grid of icons
- T-Lora Pager gets a larger font to improve readability (14 -> 16 pixels)
- Improve default widget selection in several apps (`PowerOff`, `AlertDialog`, `AppList`, `Settings`, `Boot`)
- USB HID LVGL device is now only created when necessary. And the code is called in a safer way.
- Renamed “Region & Language” to “Locale.”
- The terminal toolbar is shown only when pointer input is available.
Features:
- Implemented terminal app based on BreezyBox
- Implemented shell based on BreezyBox
- Added font-module with fixed-width fonts
Improvements:
- Improved application standard-output and error-output routing, including dynamically loaded applications.
- Updated shared icons and Material Symbols mappings.
- Other improvements & fixes
- Standardized keyboard input using Unicode-based key codes across supported devices and the simulator. Keyboards don't emit `LV_KEY_*` anymore.
- Refactored lilygo encoder driver into a reusable GPIO rotary encoder driver (see `Drivers/gpio-encoder-module/`). Added more features to the config file.
- Improved LVGL keyboard device management, including duplicate prevention and reliable reconnects.
- LVGL file mutex now registers with lvgl start/stop
- Improved LVGL startup/shutdown stability and memory allocation reliability.
- Increased simulator LVGL memory capacity and improved USB device-class handling.
- And Tab5 keyboard improvements
- Usb host keyboard improvements
- Symbols
- Requires the device.py change from CL-32 PR but that only affects visuals and not build breaking
- Fix BluetoothSettings app not updating when toggling on Bluetooth on
- Fix BluetoothSettings app crash when closing while scanning
- Fix BluetoothSettings app crash when turning BT off while scanning
- WebServer doesn't save config anymore as a side-effect of reading the config
- Add missing license headers
- Use TactilityKernel's time and delay functions instead of TactilityFreeRtos ones
