* **New Features**
* Added Material Design symbol fonts and LVGL font aliases for launcher, status bar, and shared UI icons.
* **Style**
* Migrated app icons across the UI to the new symbol font system.
* Updated launcher button sizing, font styling, recoloring and icon text color for consistency.
* Default text/icon font macros set for consistent sizing across the UI.
* **Documentation**
* Updated third‑party notices to include Material Design Icons links.
* **New Features**
* Added a standalone LVGL module and enabled LVGL support in the simulator for richer local UI testing.
* **Refactor**
* HAL and LVGL split into distinct modules; startup and device attach/detach flows reorganized for clearer lifecycle management.
* Public APIs tightened with clearer nullability/documentation.
* **Bug Fixes**
* More consistent LVGL start/stop and device attach/detach behavior for improved stability.
* **New Features**
* Time and delay utilities added (ticks, ms, µs); SD card now uses an expansion-header CS pin; HTTP downloads warn when run on the GUI task and yield to avoid blocking.
* **Bug Fixes / Reliability**
* Many hard-crash paths converted to guarded checks to reduce abrupt termination and improve stability.
* **Tests**
* Unit tests added to validate time and delay accuracy.
* **Chores**
* License header and build/macro updates.
- `TT_LOG_*` macros are replaced by `Logger` via `#include<Tactility/Logger.h>`
- Changed default timezone to Europe/Amsterdam
- Fix for logic bug in unPhone hardware
- Fix for init/deinit in DRV2605 driver
- Other fixes
- Removed optimization that broke unPhone (disabled the moving of heap-related functions to flash)
- Refactor `Ili934xDisplay` to use `EspLcdSpiDisplay` as base class
- Update `St7789Display` for changes to `EspLcdDisplayV2` related to ILI934x driver
- Updated all board driver implementations for ILI934x driver changes
- Simplified board configurations:
- All boards now have a `Configuration.cpp`
- All board config's headers are removed
- Removed `Boards.h`
- Fix for untar-ing large files
- Increase main task stack size to avoid stackoverflow when downloading apps in App Hub
- Reduce SPI frequency for ST7789 displays (according to spec)
- Added `AppHub` app
- Added `AppHubDetails` app
- Added `cJSON` dependency
- Renamed `AppSim` module to `FirmwareSim`
- Added extra `tt::app::alertdialg::start()`
- Renamed `addApp()`, `removeApp()`, `findAppById()` and `getApps()` to `addAppManifest()`, `removeAppManifest()`, `findAppManifestById()` and `getAppManifests()`
- Added `tt::lvgl::toolbar_clear_actions()`
- Added `tt::network::EspHttpClient` as a thread-safe wrapper around `esp_http_client`
- Added `tt::network::http::download()` to download files
- Added `tt::network::ntp::isSynced()`
- When time is synced, the timestamp is stored in NVS flash. On boot, it is restored. This helps SSL connections when doing a quick reset: when WiFi reconnects, the user doesn't have to wait for NTP sync before SSL works.
- Added `tt::json::Reader` as a `cJSON` wrapper
- Added `int64_t` support for `Preferences`
- Added `int64_t` support for `Bundle`
- Added dependencies: `cJSON`, `esp-tls`
- When time is synced via NTP, disable time sync.
- Added docs to 'tt::file::` functions
- Added `tt::string::join()` that works with `std::vector<const char*>`
- Fixed `tt::file::getLastPathSegment()` for the scenario when a path was passed with only a single segment
- Set `CONFIG_ESP_MAIN_TASK_STACK_SIZE=5120` (from about 3k) for all boards
- Set `CONFIG_MBEDTLS_SSL_PROTO_TLS1_3=y` for all boards
