  • Transport reconnections will not be compelled. Symfony Mailer will automatically try to reconnect.
  • Symfony Mailer will require you to explain the applicable options directly within the configuration if they are supported.
  • Codes conditional on missing methods replaced by SwiftMailer in the Laravel version 8 should now be updated with their comparable Symfony Mailer counterparts.

Accessors and mutators permit you to configure Eloquent attributes when fetching them from a model or fixing their value. For example, you want to use the Laravel encrypter to encrypt data while it is stored in the database, and then automatically decrypt the attribute when you access it on an Eloquent model.

In Laravel 9 applications, you can now use Illuminate\Database\Eloquent\Casts\\Attribute to describe accessors and mutators. This is a method to maintain a model prefix. You will now get and fix attributes using this method, in addition, determining assessors will cache object values like in custom cast classes.

This accustomed requires services like Algolia or MeiliSearch, but now you’ll eff yourself if you’re using MySQL or PostgreSQL. With Laravel Scout, you’ll be able to use the model’s toArray() method to look at the database. This new search method doesn’t require traditional indexing as you needed with Algolia.

6. Blade string rendering

Laravel 9 now provides the ability to render a blade string into its HTML equivalent. The render method validates the blade template string and also an optional data array to be used by the template.
