    • GPIO
      • Add support for character device GPIOs.
      • Remove support for preserve direction from GPIO constructor.
      • Add retry loop to direction write after export to accommodate delayed udev permission rule application for sysfs GPIOs.
      • Unexport GPIO line on close for sysfs GPIOs.
      • Fix handling of timeout=None with sysfs GPIO poll().
      • Add devpath property.
    • PWM
      • Fix chip and channel argument names in PWM constructor and documentation.
      • Add retry loop to PWM open after export to accommodate delayed creation of sysfs files by kernel driver.
      • Unexport PWM channel on close.
      • Add nanosecond period_ns and duty_cycle_ns properties.
      • Add devpath property.
    • LED
      • Raise LookupError instead of ValueError if LED name is not found during open.
      • Add devpath property.
    • Fix exception handling for Python 2 with ioctl() operations in Serial, SPI, and I2C modules.
