            "type": "vcs",
            "url": "https://github.com/laravel-shift/laravel-websockets.git"
        }
    ]
}

Then update your dependency constraint to reference this branch:

    }
}

[what-the-diff]

• Update PHP version from 8.0 to 8.1
• Update Doctrine DBAL package from 2.9 to 3.5
• Remove Guzzle PSR7 1.* and replace with 2.* (minor update)
• 5, 6: Upgrade Laravel packages for broadcasting/console/http/queueing/routing support
  from 9.* to 10.* versions (major upgrade). This is a breaking change as the major release of laravel has changed its API in some places so we need an extra step here which will be covered later on when we run our tests locally before pushing this code up into production! We also have updated Pusher's php server library too but that should not cause any issues since it was only a minor bump in their version number anyway... :)
