* Adopt PSR-2 coding style The Laravel framework adopts the PSR-2 coding style in version 5.1. Laravel apps *should* adopt this coding style as well. Read the [PSR-2 coding style guide][1] for more details and check out [PHPCS][2] to use as a code formatting tool. [1]: https://github.com/php-fig/fig-standards/blob/master/accepted/PSR-2-coding-style-guide.md [2]: https://github.com/squizlabs/PHP_CodeSniffer * Adopt PHP short array syntax Laravel 5 adopted the short array syntax which became available in PHP 5.4. * Remove SelfHandling from Jobs Jobs are self handling by default in Laravel 5.2. * Add new exceptions to `$dontReport` property * Shift core files * Shift Middleware Laravel 5.2 adjusts the `Guard` object used within middleware. In addition, new `can` and `throttles` middleware were added. * Shift Input to Request facade Laravel 5.2 no longer registers the `Input` facade by default. Laravel now prefers using the `Request` facade or the `$request` object within *Controllers* instead. Review the [HTTP Requests][1] documentation for more details. [1]: https://laravel.com/docs/5.2/requests * Shift configuration Laravel 5.2 introduces the `env` app configuration option and removes the `pretend` mail configuration option. In addition, a few of the default `providers` and `aliases` bindings were removed. * Shift Laravel dependencies * Shift cleanup * Updated composer.lock * Updated Middleware to 5.2 * Config update for Laravel 5.2 * [Laravel 5.2] Updated validation strings * Updated auth config * Updated to use middleware groups * Added laravel 5.2 sessions migration
