This release covers everything from the 2017q2 release on 2017-07-02 and has been
tested with avr-gcc v5.4.0 from Atmel and arm-none-eabi-gcc 2017q2 from Arm.
Note, that Arm did not release 6-2017-q3-update for their toolchain this quarter.

Breaking changes:

• MCP2515 revival adds new initialize API

Major features:

• No major features

Major fixes:

• Fix pin remap access (MAPR2 register) for STM32F1 XL Density series
• Fix moving average for negative averages
• Fix printf format string type violations

Known bugs:

• xpcc may generate separate IRQ handlers for shared interrupts. See #88.
• GPIO connect on STM32F1 is still broken. See #178 for discussion.
  The API from MODM will not be backported to xpcc however.
• STM32L0/L4 hardware I2C driver has limitations on restart behaviors. See #255.
• STM32F107 does not compile due to the HAL trying to remap USB. See #268.
• SCons build system emits multiple non-critical warnings. See #286.
• SCons 3.0 was released, however, our build system is not fully compatible. See #293.

New development board targets:

• OLIMEXINO-STM32 as olimexino_stm32
• STM32F051R-DISCO as stm32f0_discovery

New device drivers:

• AD79x8
• LTC298x
• AMSYS5915
• MCP2515 (revived)
