* Trait `PhpSchool\CliMenu\MenuItem\SelectableTrait` was removed. Copy the old code into your menu item

if you need it.

* Methods `PhpSchool\CliMenu\Builder\CliMenuBuilder#setUnselectedMarker()` & `PhpSchool\CliMenu\Builder\CliMenuBuilder#setSelectedMarker()` were removed.

Customise markers on the individual item styles:

```php

<?php

use PhpSchool\CliMenu\Builder\CliMenuBuilder;

use PhpSchool\CliMenu\Style\SelectableStyle;

$menu = (new CliMenuBuilder)

->modifySelectableStyle(function (SelectableStyle $style) {

$style->setUnselectedMarker('❅ ')

->setSelectedMarker('✏ ')

// disable unselected marker

->setUnselectedMarker('')

;

})

->build();

```

* Method getStyle() was added to interface PhpSchool\CliMenu\MenuItem\MenuItemInterface. Items must now implement this

method. For selectable items use `\PhpSchool\CliMenu\Style\SelectableStyle` or a subclass of. For static items use

`\PhpSchool\CliMenu\Style\DefaultStyle` or a subclass of.

* `PhpSchool\CliMenu\MenuStyle` marker methods have been removed. If you were using these directly. Operate on the item

style object instead.
