 # Changelog
 
-**2.2.0 - 25/10/2017**
+**Unreleased**
+* Updated `create_dot_transition()`to improve the display of timed & non-timed transitions
+* Added `id` member to `State` struct
+* Updated [fsm_graph.ino](https://github.com/LennartHennigs/arduino-fsm/blob/master/examples/fsm_graph/fsm_graph.ino) example to explain naming
+* Updated `make_transition()` as suggested in [#22(https://github.com/jonblack/arduino-fsm/issues/22)] and [#35](https://github.com/jonblack/arduino-fsm/issues/35)
 
+
+**2.3.0 - 01/04/2018 (L. Hennigs)**
+* Added `get_dot_definition()` function to FSM to get the FSM graph in [.dot syntax](http://graphs.grevian.org/example)
+* Added `get_current_state()` function to FSM
+* Added `on_transition()` function to FSM
+* States now need to be named, transitions can be named - names are needed for graph generation
+* Added webserver example to show a autogenerated FSM graph
+* Added `CallbackFunction` struct
+* Added `ESP8266` as a possible target architecture in `library.properties`
+* Fixed `light_switch` example
+* Fixed `timed_switchoff` example
+* Updated `keywords.txt`
+
+
+**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
