commerce 7.x-1.4

Drupal Commerce now depends on Drupal >= 7.15.

Drupal Commerce 1.4 is a maintenance release incorporating 87 patches from 40 contributors around the world. These patches add a variety of new features to the core of Drupal Commerce and make it more performant and suited to international usage. The release notes summarize some of the main changes in the new version and includes a full changelog for the curious.

New features

The Add to Cart form and checkout form have both seen improvements. Most notable on the checkout form is the new setting to allow copying of fields from one customer profile to another. This feature was a part of the Commerce Shipping module but was moved to core and designed to work server side across multiple checkout pages and even between customer profile types that may have different fields. The Account information checkout pane was also updated to support e-mail address verification through double entry.

We included a variety of Views integration improvements, including adding a missing handler, updating area handlers for Views 3.5, supporting redirect destinations on our entity operation links, and adding a node filter to only show product display nodes.

Finally, we added a few features to make it simpler for site builders to build product pricing rules. Foremost among these is a new Price comparison condition that supports multi-currency price comparisons and accepts input in major currency unit decimal values instead of minor unit integer values (i.e. compare in Dollars or Euros instead of Cents). We also added a read only computed property allowing you to use the generic Data comparison condition against these major unit decimal values.

Performance

The primary performance improvements involve lowering Drupal Commerce's memory footprint. We reduced the number of times we build the full array of entity information and reduced the number of Rules loaded into memory during tax calculation.

Previously, the Cart module duplicated some queries during shopping cart order loading, so a small static cache was moved earlier in the cart loading process to stop them.

Finally, some operations (like creating a new product type or deleting a tax rate) require menu items to be rebuilt, but instead of doing so immediately (and potentially multiple times on a single page request), we are delaying the rebuild by using the 'menu_rebuild_needed' variable instead of directly calling menu_rebuild(). Contributed modules that followed Drupal Commerce's lead in directly calling menu_rebuild() should also be updated to use this variable instead.

Internationalization

With every new release, Drupal Commerce becomes better suited for use in more countries - thanks especially to the contributions of community members from these countries doing testing and providing valuable feedback. Drupal Commerce 1.4 includes currency format updates and RTL support in our CSS files. To improve product translation and management, plach contributed a fresh integration to the latest development in the Entity Translation module, and OnkelTem ensured the product language property is properly exposed to the Entity API and Rules.

Additionally, we found a need for 0% VAT rates to actually be applied and displayed in some instances, so the tax calculation code and inline documentation has been updated accordingly. Developers building sites requiring VAT should check out the Commerce European Union VAT module for additional assistance in getting taxes right.

Notable bug fixes

Two bug fixes deserve special mention for the amount of discussion they've generated. The first is a long standing incompatibility with the Display Suite module caused by the fact that both modules depend on hook_entity_info_alter(). Sites using Display Suite to add view modes to product display node types were not finding the related view modes in the product type settings, because Drupal Commerce's implementation of the hook was being invoked first. To fix this, we're taking advantage of Drupal 7's hook_module_implements_alter() to ensure that commerce_product_reference_entity_info_alter() will be called last when that hook is invoked to solve the incompatibility.

Additionally, we have implemented a fix to prevent the payment checkout pane from being submitted if there are errors elsewhere on the page. The checkout form was designed to validate and submit checkout pane forms independently, but there are cases where checkout pane submission should be dependent on the validation and submission of other panes on the form. As an immediate fix to the most pressing use case, we added a check to the payment checkout pane to prevent it from attempting payment if there are any form errors on the page. This will prevent duplicate payment attempts when the payment checkout pane is used on a single page checkout form.

Updating from previous versions

When updating to Drupal Commerce 1.4, remember to run update.php. There are a few schema updates that must be performed to accommodate a minor API change - entity IDs and revision IDs will default to NULL both in code and in the database.

Sites that have customized the checkout form through form alteration or theming may also need to accommodate a minor update to the way error messages are displayed. Instead of appearing above checkout panes, error messages related to the contents of a checkout pane will now be displayed inside the checkout pane's fieldset or container div.

Finally, as part of the update to our Entity Translation integration, Drupal Commerce 1.4 depends on Drupal >= 7.15. For reference, Drupal 7.16 was a security release, so sites have good reason to update Drupal core regardless.
