Changelog and Upgrade Instructions
==================================

## 0.2.x to 0.3.x

Major changes:

  * The `Shell::EV_*` constants have been renamed to `Shell::EVT_*`.
  * The `configure` method has been removed. If you really need to
    extend the `Shell` class, use the constructor to configure your
    shell (see *examples/timers.php*)
  * Events are now dispatched using the *NoccyLabs/TinyEvent* library.
    The main difference here is in how the event object received. The
    shell instance is now passed in the object, and you can provide any
    userdata to be passed on to the handler when you add the listener.
  * The event `Shell::EVT_BAD_COMMAND` will be fired if a command can
    not be found, assuming `Context->execute()` does not accept the
    command. (see *examples/commandevents.php*)

New features:

  * Tasks can now be added and removed from the shell. Tasks will receive
    a call to their `update()` method once per main loop, until they are
    removed or return false from the `isValid()` method. Tasks need to
    implement the `TaskInterface` interface. (see *examples/tasks.php*)
