Upgrade Guide

• Livewire's before/afterDomUpdate hook has been conformed to the new standard for registering hooks.

// Before
window.livewire.beforeDomUpdate(() => {})
window.livewire.afterDomUpdate(() => {})

// After
window.livewire.hook('beforeDomUpdate', ({ html }) => {})
window.livewire.hook('afterDomUpdate', () => {})

Release Notes

Added

• Allow "single-value" event listeners:
  protected $listeners = ['open' => 'open']; can now be shortened to: protected $listeners = ['open'];
• Ability to update the query string from public property data changes:

class Foo extends Component
{
    public $foo = 'bar';

    // This makes it so that ?foo=X will be updated in the query string everything the property value changes.
    protected $updatesQueryString = ['foo'];

    public function mount()
    {
        // You can easily set the initial value of a property from the query string like you would in a controller.
        $this->foo = request()->query('foo', $this->foo);
        ...
