Decide what to do next

You have two options:
    1.
    Migrate to the new Storefront UI
    2.
    Stay at the current UI

Migrate to the new Storefront UI

Spree 4.1 comes with a completely new mobile-first ultra-fast Storefront powered by Turbolinks.
To replace your current frontend with the new Spree UI follow these steps:
    1.
    Update Spree Auth Devise to 4.1 in your Gemfile
    1
    gem 'spree_auth_devise', '~> 4.1'
    Copied!
    2.
    In your project root directory run:
    1
    rails g spree:frontend:copy_storefront
    Copied!
    WARNING this will overwrite your current project templates, it's required for the new UI, so if you'll be asked by the generator what to do please choose A to proceed
    3.
    Next, you will need to copy over two files:
    4.
    If you overwrote any spree_frontend controllers you will need to either remove your local copies or move your custom logic to decorators
    5.
    The same goes for helpers
    6.
    You will also need to remove this line:
    1
    //= require spree/frontend/spree_auth
    Copied!
    from vendor/assets/javascripts/spree/frontend.all.js file

Stay at the current UI

If you wish to not move to the new Storefront UI it's still an option. Just proceed with the steps described below.
    1.
    Keep Spree Auth Devise at the version you're currently using
    If you're using Spree Auth Devise gem you need to lock it at 4.0.0 in your Gemfile:
    1
    gem 'spree_auth_devise', '~> 4.0.0'
    Copied!
    2.
    Copy over all views from Spree 4.0
    Copy overviews from: https://github.com/spree/spree/tree/4-0-stable/frontend/app/views to your application views directory: app/views
    WARNING remember to not overwrite your customizations!
    3.
    Copy over all Stylesheets from Spree 4.0
    WARNING remember to not overwrite your customizations!
    4.
    Copy over all JavaScript from Spree 4.0
    WARNING remember to not overwrite your customizations!
