There were a few changes needed:
* Plugins are now specified through `plugin:` config keyword.
* All plugin gems need to be specified explicitly in Gemfile since they
are no longer dependencies of plugins already specified explicitly.
* All plugin gems need to be updated in other to use the new APIs.
* One cop was renamed.
* New offenses safe to correct were corrected directly with `bundle exec
rubocop -a`.
* New offenses unsafe to correct were added to the TODO configuration
with `bundle exec rubocop --auto-gen-config --auto-gen-only-exclude
--exclude-limit 1400 --no-auto-gen-timestamp`.
The old Paperclip configuration was very clever and easy to use but it
was also a complicated implementation building on the complicated Spree
preference system.
I simplified this with Active Storage, storing simple references to blob
ids and default URLs as backup.
Fixes:
Spree::Preferences::Preferable persisted preferables requires a valid id but returns default values
Failure/Error:
