*****************************************************************************
*** 2.5.0 ***
- FIX: Fixed various minor documentation errors and fixed ADC maximum
frequency limit in STM32F2/F4 ADC drivers (bug 3484942)(backported
to 2.4.1).
- NEW: Updated debug plugin 1.0.8 (backported to 2.4.0).
- NEW: Added more accurate UBRR calculation in AVR serial driver (backported
to 2.4.0).
