Drupal 8.3.0

7 April 2017

Drupal version 8.3.0 is now available (major release).

Upgrading to Drupal 8.3.0

What's New in Drupal 8.3.0

• Added the Workflows module (experimental) which abstracts transitions and states from Content Moderation into a separate component for reuse by other modules implementing non-publishing workflows.
• Added the Layout Discovery module (experimental) which provides an API for modules or themes to register layouts.
• Added the Field Layout module (experimental) which provides the ability for site builders to rearrange fields on content types, block types, etc. into new regions, for both the form and display, on the same forms provided by the normal field user interface.

• Updated to Twig 1.25.
• Updated to jQuery 2.2.4.
• Updated to CKEditor 4.6.2 (with new Moono-Lisa skin).
• Updated Symfony components to 2.8.18.
• Updated PHPUnit to 4.8.35.
• Applied patch-level updates to the latest versions for all dependencies wherever possible. Minor updates applied for Symfony PSR-7 Bridge and Zend Stdlib, which Drupal does not depend on directly.

• Advance notice: Internet Explore 9 and 10 will no longer supported from 8.4.x, scheduled for October 2017. Microsoft has now ended support for these browsers. Drupal will still support Internet Explorer 11 and its replacement, Edge.

• Updated the BigPipe module from beta to stable.
• Updated the Migrate module from alpha to beta.
• See https://www.drupal.org/core/experimental#versions for more information about the stability levels of experimental modules.

• Can now drag and drop images into image fields in Quick Edit mode.
• Image fields are now limited to only accepting images, so that users on mobile clients are not offered a confusing and non-functional video upload option.
• CKEditor now utilizes the AutoGrow plugin to better take advantage of larger screen sizes.

• Redesigned status report.
• Standardized display of Views overview page to more closely match that of other administrative overview pages.
• Views filter order now matches the table column order below in Content and People overview pages.
• The "Allowed HTML tags" input has been converted to a textarea, which significantly improves the usability of HTML filter configuration.
• Removed the 'disabled' region from block administration.
• Incoming paths are again case-insensitive for routing, similar to earlier major Drupal versions.

• Refactored to use new experimental Workflows module.
• Now supports moderation of non-translatable entity types.
• When reverting a moderated revision, the moderation state is now reverted too.
• Added an API to create and enforce default workflow states and transitions.
• Allow moderation of entity types without bundles, as long as they have revisions.
• Publishes any entity type that implements EntityPublishedInterface, not just Nodes.

• Drupal 7 core node translations are now migrated to Drupal 8.
• Configuration translation support is added to migrations in general and implemented for Drupal 6 user profile fields.

• REST API now supports the registering of users.
• Anonymous REST API performance increased by 60% by utilizing the internal page cache.
• Improved the response bodies and status codes for requests with incorrect request headers or request bodies, in dozens of situations.
• Massive overhaul of the test coverage.
• 403 responses now return reason why access was denied.
• Serialized values for Booleans and integers are now returned as the correct data type, rather than incorrectly typed as strings.

• Optimized class loader detection made more generic to support class loaders other than ApcClassLoader.
• ViewsData and Token info cache now use the default cache bin to prevent APCu memory from being filled too quickly.
• Improve statistics performance by adding a swappable backend.

• Deprecated several routing services in favor of two more unified services.
• Replaced the deprecated Symfony ExecutionContextInterface by subclassing from ConstraintValidator to prepare for an update to Symfony 3.
• EntityPublishedInterface and EntityPublishedTrait have been added to give a generic publishing API, and are being used by Node and Comment entity types.
• Added a collection label to EntityType. This is a plural uppercase label for a collection of entities - e.g. "Workflows".

• Officially adopted short array syntax and updated all of core accordingly.
• PHP CodeSniffer and Drupal Coder have been added as composer dev requirements, so they can be installed automatically with `composer install --dev` rather than requiring separate installation. (Do not use `composer install --dev` for production sites.)
• Most global constants in Drupal 8 have been deprecated in favor of class constants. As a best practice, use appropriate class constants rather than global constants.

• Integrated PHPUnit verbose output in SimpleTest UI.
• Improved backward compatibility with WebTestBase.
• Improved backward compatibility between BrowserTestBase and WebTestBase.
• Many old WebTestBase tests have been moved to BrowserTestBase.
• Expanded automated test coverage for JavaScript.

• composer.json now uses the new official endpoint for modules and themes, packages.drupal.org.
• Custom modules and themes can now be installed to correct locations using composer.
• Added Package.json enabling new JavaScript language features.
