Laravel 5.8.9 Released

The Laravel team released Laravel 5.8.9 this week, adding opt-in event discovery and the latest fixes and changes in the Laravel 5.8 release.

First, you should check out Taylor’s implementation and discussion around event discovery in PR #28064. Event discovery is an opt-in feature in Laravel 5.8, which means that you must explicitly define the following method in your EventServiceProvider class, returning a Boolean true:

/**
 * Determine if events and listeners should be automatically discovered.
 *
 * @return bool
 */
public function shouldDiscoverEvents()
{
    return true;
}

By default, the base Illuminate EventServiceProvider returns false by default in Laravel 5.8.

If you want to opt-in, you will probably want to cache the event discovery with the new artist event:cache command. The discovery feature uses reflection to determine event listeners/handlers on the fly in development, but caching avoids that overhead in production. You can run this command via a composer script command event or somewhere in your build pipeline.

Taylor Otwell also discussed Event / Listener discovery in his podcast Laravel Snippet #10— you should give his podcast a listen.
