The first stop on our Laravel 6 tour is lazy collections, contributed by Joseph Silber. This is easily one of my favorite additions to Laravel 6. While a traditional Collection wraps an array, a LazyCollection leverages generators to significantly reduce memory consumption issues, while still offering the same elegant chaining that you've become accustomed to.

The new default error page in Laravel 6 is something special. Contributed by the teams behind Spatie and Beyond Code, Ignition is a gorgeous and extensible error screen.

When installing a fresh Laravel 6 application, you'll notice that the login and registration scaffolding, as well as the Vue/jQuery/Bootstrap boilerplate in your app.js file have been extracted to a new Composer package: laravel/ui. This helps to clean up the default install, while allowing the package to be versioned separately from the framework.

Laravel 6 ships with improved support for Eloquent subqueries, thanks to a few PRs from Jonathan Reinink. You may now add subqueries by using the new addSelect() method, or by passing a closure to the orderBy() and from() methods of the query builder. I'll show you how in this lesson.
