2.0.0

• Keypress now has a listener class that must be instantiated. The functions that were previously in the global window.keypress object are now public methods of the window.keypress.Listener class.
• Each instance of a Keypress listener can be bound to a DOM element by passing in the element to the listener's constructor.
• Combos now default to being ordered (the property is now called is_unordered and is false by default).
• Combos' handlers preventDefault unless the handler returns true.
• The "combo" public method is now called "simple_combo".
• The basic combo helpers for simple, counting and sequence combos no longer have a third prevent_default optional parameter.
• Debugging console logs can be enabled by setting keypress.debug to true.
• All key event callbacks send a third argument specifying whether the event is firing again automatically because the key has remained pressed down.

1.0.9

• Fix escape key bug. Issue #17.
• Fix unregister bug. Issue #24.

1.0.8

• Ensure that on_release is called for all combos, not just counting combos.
• Fix bug that was causing is_ordered to be ignored.
• Fixed an edge case for a counting combo's count not being reset.
• Improve how key events are bound

1.0.7

• Fixed combo matching to prevent performance issues as more keys are pressed.

1.0.6

• Fixed a bug with exclusive combos not properly excluding each other in some cases.
• Feature added to allow for combos that do not fire if unrelated keys are also pressed ("is_solitary" boolean).

TODO

• Put negative edge in sequences.
• See if we can do away with keyup_fired and count properties.
