Core

• Sandbox generator and installer now use the correct 2-0-stable branch of spree_auth_devise
  3179a7a & 759fa34.

• Product requires shipping_category_id on create #3188.

  Jeff Dutil

• No longer set ActiveRecord::Base.include_root_in_json = true during install.
  Originally set to false back in 2011 according to convention. After
  https://groups.google.com/forum/#!topic/spree-user/D9dZQayC4z, it
  was changed. Applications should now decide their own setting for this value.

John Dyer and Sean Schofield

• Revert bump of Rubygems required version which made Spree 2.0.0 unusable on Heroku. 77103dc

  @actven

• Improve performance of Order#payment_required? by not updating the totals every time. #3040 #3086

  Washington Luiz

• Remove after_save callback for stock items backorders processing and
  fixes count on hand updates when there are backordered units #3066

  Washington Luiz

• InventoryUnit#backordered_for_stock_item no longer returns readonly objects
  neither return an ActiveRecored::Association. It returns only an array of
  writable backordered units for a given stock item #3066

  Washington Luiz

• Scope shipping rates as per shipping method display_on #3119
  e.g. Shipping methods set to back_end only should not be displayed on frontend too

  Washington Luiz

• Translation for admin tabs are now located under the spree.admin.tab key. Previously, they were on the top-level, which lead to conflicts when users wanted to override view translations, like this:

en:
  spree:
    orders:
      show:
        thank_you: "Thanks, buddy!"

See #3133 for more information.

• Change order.promotion_credit_exists? api. Now it receives an adjustment
  originator (PromotionAction instance) instead of a promotion. Allowing
  multiple adjustments being created for the same promotion as the current
  PromotionAction / Promotion api suggests #3262

• Washington Luiz *

• CreditCard model now validates that the card is not expired.

  Ryan Bigg

• Payment model will now no longer provide a vague error message for when the source is invalid. Instead, it will provide error messages like "Credit Card Number can't be blank"

  Ryan Bigg

• Calling #destroy on any PaymentMethod, Product, TaxCategory, TaxRate or Variant object will now no longer delete that object. Instead, the deleted_at attribute on that object will be set to the current time. Attempting to find that object again using something such as Spree::Product.find(1) will fail because there is now a default scope to only find non-deleted records on these models. To remove this scope, use Spree::Product.unscoped.find(1). #3321

  Ryan Bigg

• Removed variants_including_master_and_deleted, in favour of using the Paranoia gem. This scope would now be achieved using variants_including_master.with_deleted.

  Ryan Bigg

• You can now find the total amount on hand of a variant by calling Variant#total_on_hand. #3427

  Ruben Ascencio

• Tax categories are now stored on line items. This should make tax calculations slightly faster. #3481

  Ryan Bigg

API

• PUT requests to Checkouts API endpoints now require authorization to alter an order.

  Ryan Bigg

• The Products API endpoint now returns an additional key called shipping_category_id, and also requires shipping_category_id on create.

  Jeff Dutil

• Checkouts API's update action will now correctly process line item attributes (either line_items or line_item_attributes)

  • Ryan Bigg*

• Checkouts API now correctly processes incoming payment data during the payment step.

  Ryan Bigg

• Fix issue where set_current_order before filter would be called when CheckoutsController actions were run, causing the order object to be deleted. #3306

  Ryan Bigg

• An order can no longer transition past the "cart" state without first having a line item. #3312

  Ryan Bigg

• Attributes other than "quantity" and "variant_id" will be added to a line item when creating along with an order. #3404

  Alex Marles & Ryan Bigg

Backend

• Symbolize attachment style keys on ImageSettingController otherwise users
  would get undefined method `processors' for "48x48>":String> since
  paperclip can't handle key strings.

Washington Luiz

• Fix bug where taxonomy URL was incorrect when Spree was mounted at a non-root path 50ac165.

  Washington Luiz

• Fixed issue where selecting an existing user in the customer details step would not associate them with an order.

  Ryan Bigg and dan-ding

Frontend

• Fix issue where "Use Billing Address" checkbox was unticked when certain
  browsers autocompleted the checkout form. #3068 #3085
