4.5 to 4.6

This guide covers upgrading a 4.5 Spree application to Spree 4.6.
If you're on an older version than 4.5 please follow previous upgrade guides and perform those upgrades incrementally, e.g.
This is the safest and recommended method.

Update Gemfile

gem 'spree', '>= 4.6.0'
Update all other spree gems used in your application to 4.6.0 or version compatible with 4.6:
gem 'spree_sample', '~> 4.6.0'
gem 'spree_emails', '~> 4.6.0'
gem 'spree_frontend', '>= 4.6.0'
gem 'spree_backend', '>= 4.6.0'
gem 'spree_gateway', '~> 3.10'
gem 'spree_auth_devise', '>= 4.5.0'
gem 'spree_i18n', '~> 5.1'

(Optional) Remove spree_globalize

If your application used the spree_globalize extension, you can remove it from your Gemfile, as translations are now supported out-of-the-box with the Mobility gem.
We've configured Mobility to use a strategy that uses a separate table to store translations, just like how spree_globalize did. This means, you won't need to make any changes to the database structure or migrate data.
During the upgrade process, you may need to review your custom queries that rely on translations, as there are minor differences in how Mobility handles them. Spree 4.6 includes a few built-in concerns to make it easier to work with translatable models.

Update gems

bundle update

Install missing migrations

bin/rake railties:install:migrations

Run migrations

bin/rails db:migrate
Note: If you didn't use spree_globalize before, this will install migrations that move some columns from spree_products, spree_taxons, to dedicated translation tables -> spree_products_translations, spree_taxons_translations etc.
If you're using raw SQL queries (either in the application code, or running in external tools), you may need to review the new structure and update your queries accordingly.

Run Additional Commands for Frontend

If using Spree Frontend, run the following additional commands to get everything set up correctly with the updated gems:
bin/rails javascript:install:esbuild
bin/rails turbo:install
bin/rails g spree:frontend:install
yarn build
And that's a wrap!
🎉
