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*)
