v0.5.5

• New features
  • true and false can now be passed to Gpio.write/2
• Bug fixes
  • Include i2c-dev.h to avoid incompatible version on Raspbian 8. This also
    avoids errors on systems that don't have the header file for whatever
    reason.
  • Include asm/ioctl.h for a MIPS platform that doesn't include it
    automatically.
