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.
- Moved WiFi logic from `TactilityKernel/` to `wifi-module`
- Created commandline app to control Wi-Fi
- Update `tactility.py` to v6.1.0 so it can be executed directly
DTS modules (device modules) often have a single source file with an empty `struct Module`.
The module's yaml file now allows a `dts-only` boolean to be set, so the source file becomes optional.
`devicetree.yaml` is renamed everywhere to `module.yaml`
app-module
- Apps now have support for:
- environment variables (inherit from parent app)
- current workdir
- window size (when running in terminal)
- Add type aliases like `AppId` and `PackageId`
- Remove data duplication between ledger and app instance records: create `AppManifestSet`
- `AppManifest` usage safety improved: pass by value where needed, or use `AppId` instead of a manifest.
Terminal and shell
- Moved shell commands into coreutils-module as proper apps.
- Refine stack size for terminal and shell because apps now run with their own task and stack (including in-memory apps)
Platform
- Fix for listing root dir on ESP32: wrap posix directory functions and wire in file systems.
- Moved all platform-specific file system init code to platform subprojects
Other
- Fix for screenshot capture (issue with paths)
- Fixes for coreutils app correctness
- Memory optimizations (use more PSRAM where possible) in various locations such as app-module, shell and terminal.
- `ls` and `help` commands now use terminal width and show columns of data by default
- Created fs helpers at `TactilityKernel/include/tactility/filesystem/fs.h` (partially ported from `ShellFs`)
app-module:
- Implement `AppStartContext` to reduce amount of `app_start_` and `app_exec` functions: replace them with `app_start_with_context()`
- Add support for environment variables when starting apps
- Implement support for environment variables for apps
graphics-module:
- Add this new module
- Move font-module code into this module
- Implement pixel_buffer
apps:
- Terminal app: reduce memory usage by only buffering a single row of characters, and try to buffer in IRAM when possible. Implement new pixel_buffer.
- App List: Mark apps as favourite to pin them on top. Use touch or press "x" key.
- App List: Add toolbar button that shows alert dialog with info about using favourites
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
USB Audio Class (UAC) output
Audio codec re-binding
Keyboard / Bluetooth HID
HID Consumer Control (media keys)
Symbol exports
Other fixes
IMU-based screen auto-rotate

- 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.

- Fixes for app stdio
- Removed TactilityC, moved its symbols to existing modules and several new ones (pthread-module, c-symbols-module, cpp-symbols-module, posix-symbols-module, freertos-module).
