-For any addons you might have upgraded, please double-check if they have an upgrade guide. For example:
-- Xx package has the upgrade guide here;
-- Yy package has the upgrade guide here;
+**backpack/file-manager** Using the File Manager package? Most of the views that weren't in use  were removed, and the dependencies were bumped. If you didn't do any customization you should delete the `resources/views/vendor/elfinder` (`rm -rf resources/views/vendor/elfinder`) folder. 
+No need to publish any views anymore if you are not customizing them. If you were, publish the new view files (`php artisan vendor:publish --provider="Backpack\FileManager\FileManagerServiceProvider" --tag="elfinder-views"`). Then apply your customization on the new files, now located at: `resources/views/vendor/backpack/filemanager/`
+
+Additional the `browse` and `browse_multiple` **fields/columns** are now part of this package. If you previously made any modifications to this fields/columns you should publish the new views (`php artisan vendor:publish --provider="Backpack\FileManager\FileManagerServiceProvider" --tag="filemanger-fields"` and `php artisan vendor:publish --provider="Backpack\FileManager\FileManagerServiceProvider" --tag="filemanager-columns"`), and carry over the modifications from the old files to this new files.
