Change Log
==========

0.5.0a
------
- Added new edge detection events (interrupt handling)
  - Added add_event_detect()
  - Added remove_event_detect()
  - Added add_event_callback()
  - Added wait_for_edge()
- Removed old experimental event functions
  - Removed set_rising_event()
  - Removed set_falling_event()
  - Removed set_high_event()
  - Removed set_low_event()
- Changed event_detected() for new edge detection functionality
- input() now returns 0/LOW == False or 1/HIGH == True (integers) instead of False or True (booleans).
- Fix error on repeated import (issue 3)
- Change SetupException to a RuntimeError so it can be caught on import (issue 25, Chris Hager <chris@linuxuser.at>)

- Added set_rising_event()
- Added set_falling_event()
- Added set_high_event()
- Added set_low_event()
- Added event_detected()
