Place the package code inside your Laravel project (e.g. packages/BugFinder/version-upgrade) then add to composer.json autoload (or use path repository).

Run composer dump-autoload then add provider if automatic discovery not available.

Features

Adds routes, controller, service and view for version upgradation.
Merges a version_upgradation menu item into runtime config('generalsettings.settings') so the menu appears without editing files.
Provides an artisan command to permanently inject the menu into config/generalsettings.php:

php artisan version-upgrade:inject-config

Notes

The injection command makes a backup at config/generalsettings.php.bak.version-upgrade before editing.
You should review the changes before committing them.
