3.5 to 3.6
This guide covers upgrading a 3.5 Spree application, to a 3.6 application.
gem 'spree', '~> 3.6.1'
gem 'spree_auth_devise', '~> 3.3'
gem 'spree_gateway', '~> 3.3'
You can still use paperclip for attachment management by setting
SPREE_USE_PAPERCLIPenvironment variable to
true, but keep in mind that paperclip is DEPRECATED and we will remove paperclip support in Spree 4.0.
You're good to go!
Run your test suite, click around in your application and make sure it's performing as normal. Fix any deprecation warnings you see.
