Fly System
● Laravel 9 has migrated from fly system version 1 to fly system version 3.
● Fly system is the library that provides all file manipulation methods by the storage in laravel.
● In late 2020, the fly system was rewritten from the ground up to bring several new features and use some of the language features of php7.
● Laravel 9, we have tried to make the upgrade as seamless as possible. But, some changes may be required within your application.
● You need a version 3 of the aws f3 adapter and sftp adapter. If you use them in your application.
● If you do not want to overwrite you will need to check manually for the file’s existence before performing any of the mentioned operations. Also attempting to read from a file that doesn't exist now returns null; it used to throw an exception in laravel 8.

Swift Mailer to Symphony Trailer
● In laravel 9 is the transition from swift mailer to symphony trailer.
● well swift mailer is no longer maintained as of december 2021.
● Laravel has been relying on it for all its mail sending capabilities.
● Mainly you will need to replace some of your application dependencies to be able to send mail.
● Also some of the methods have been renamed, most of these methods are low level methods.
● which used to interact with symfony mailer and previously swift mailer.
Q Flash Command
● Laravel 9 failed job database, table, stores, information about your failed queue drops. This table can become quite large and eat a lot of space we have seen that reports several times.
● So, periodically cleaning up the table is a smart move.
● Laravel already has a php arts and q flush command that will delete all the entries in the table.
● But it makes more sense to delete only the old entries not the entire table
● And for that reason laravel 9 comes with a new hours option on the q flash command.
● That option can be used to configure the number of hours to return to keep failed job data in the database.

Collision
● Back in April, Laravel 8.37 came with anonymous migration support.
● which solves an issue when migration classes name collision.
● The problem happens when many migrations have the same class name. Then You try to migrate the database from scratch.
● The solution was to use anonymous classes instead of named classes
● In Laravel 9 the migration stops now using anonymous classes by default.
● When you run php and make migration the class created will be an anonymous class.
● Now you can create migrations without worrying about collisions with older migrations with the same name.
Guzzle http Client
● Most new users know that laravel ships with an expressive http client that’s spelled around the guzzle http client.
● In guzzle, if the request you are trying to make doesn’t receive a response the process will completely freeze.
● If the request was made from inside a cue job the worker will freeze and won’t even respond to the timeout signal.
● To deal with issues the http client and laravel 9 will have a default timeout of 30 seconds.
● This time out will force guzzle to stop waiting for a response.
● Throw an exception that you can handle by the laravel exception handler like all others.
● Forcing a timeout like this will ensure that workers skip the job that has a stuck gaza request.
● If you want to override this default behaviour you can use the timeout method on the client before sending any request.
● In this example here the client will wait for 60 seconds before throwing at an exception.
● In all cases we don’t recommend disabling this default timeout.
● As it may cause serious issues for your applications running in production especially to your q drops.
● You may now use the controller method to define the common controller.
● For at the routes within the group using the controller method of the route facade.
● This method accepts the name of the controller class then when defining the routes inside the group.
● You only need to provide the controller method that they invoke.
● Another addition in laravel 9 is the ability to use and route binding.
● Php 8.1 added support for enumerations.
● An enumeration or an innum for short is an enumerated type that has a fixed number of possible values.
