Changelog

2.2.0 - 25/10/2017

• Add on_state() handler to states
• New run_machine() method to invoke machine execution (includes a check_timed_transitions() call)
• New timed_switchoff.ino example sketch to ilustrate new on_state() and run_machine() funcionality
• Corrections:
  • make_transition() correctly initialices timed transitions start milliseconds (make_transition() is now a fsm method)
  • Initial state on_enter() handler is now correctly executed on fsm first run
  • Removed Serial.println(now); trace in Fsm.cpp
  • Correct initialization of m_num_timed_transitions

2.1.0 - 21/11/2015

• Add timed transitions

2.0.0 - 03/09/2015

• Remove AUTHORS files: too much hassle to maintain
• Add library.properties
• Add keywords.txt
• Remove name attribute from state
• Use int for transition event instead of string

1.0.0 - 24/12/2013

• Initial release.
