- `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)
