- DEVICE_ are generated from targets.json file, device.h deprecated
- Callback replaces FunctionPointer to provide std like interface
- mbed HAL API docs improvements
- toolchain - prexif attributes with MBED_
- add new attributes - packed, weak, forcedinline, align
- target.json - contains targets definitions
- ST - L1XX - Cube update to 1.5
- SPI clock selection fix (clock from APB domain)
- F7 - Cube update v1.4.0
- L0 - baudrate init fix
- L1 - Cube update v1.5
- F3 - baudrate init fix, 3 targets CAN support
