Core compatibility: 8.x
Release type: Bug fixes, New features

Release notes

This is a minor version (feature release) of Drupal 8 and is ready for use on production sites. See the CHANGELOG.txt for a summary of changes and improvements since the last minor release. Learn more about Drupal 8 and the Drupal 8 release cycle.

This minor release provides new improvements and functionality without breaking backward compatibility (BC) for public APIs. Note that there may be changes in internal APIs and experimental modules that require updates to contributed and custom modules and themes per Drupal core's backwards compatibility and experimental module policies. Note that both policies have been updated for the 8.1.x release.

Note that 8.1.0 is the first stable release to use Composer for packaging its third-party dependencies. If your site is installed from a Drupal git repository, you must now run composer install to create the third-party vendor directory. There is no change for sites installed from packaged releases (from tar or zip archives, normal Drush installation, etc.). See the change record on the Composer change for more detail.

New stable features

The following new stable features have been added to Drupal 8.1.0:

API and developer improvements

Drupal 8.1.0 includes numerous improvements for the entity system. Modules requiring Drupal 8.1.0 or later can take advantage of these backwards-compatible API improvements:

Other API and developer improvements in 8.1.0:

See the Drupal core change records for additional information on API changes. Translators should take note of a handful of minor string changes since the last release.

Experimental modules

The following modules are considered experimental for this release. Experimental modules are provided with Drupal core for testing purposes, but are not yet fully supported.

Migrate, Migrate Drupal, and Migrate Drupal UI (alpha stability)
This release now provides an alpha-stability user interface for Drupal core migrations! Use these modules to migrate Drupal 6 or 7 sites onto Drupal 8. See the user guide on migrating from Drupal 6 or 7 to Drupal 8 for more information.
Always back up your data before performing a migration, and be sure to take note of the outstanding issues below:
  • The Drupal 6 to Drupal 8 migration should be considered alpha stability, but may be suitable for upgrading many existing Drupal 6 sites with careful testing.
  • The Drupal 7 to Drupal 8 migration is incomplete, but is suitable for developers who would like to help improve the migration, and can be used to test upgrades especially for simple Drupal 7 sites.
  • Issues tagged Migrate critical are blockers for these modules being considered stable. In particular, the user interface does not yet support incremental migrations.
  • Drush support is still only available in the Migrate Upgrade contributed module, but the core UI now replaces the contributed module UI, and using the contributed module together with core may have unexpected results until it is updated.
  • Note that the module for the user interface has been renamed to "Migrate Drupal UI" since RC1. You will need to enable all three modules to perform a migration.
  • BigPipe (alpha stability)
    Provides an advanced implementation of Facebook's BigPipe page rendering strategy, leading to greatly improved perceived performance for pages with dynamic, personalized, or uncacheable content. See the BigPipe handbook page.

    If you previously installed the BigPipe contributed module, you must uninstall and remove it before upgrading from Drupal 8.0.x to 8.1.x.

    Inline Form Errors (alpha stability)
    This provides a proof-of-concept for showing form errors inline. It has not changed significantly from 8.0.0. Be aware that this module has outstanding issues, some of which are significant.

    Third-party library updates

    Changed coding standards

    Drupal 8.1.0 has adopted the following coding standards changes:

    Important bug fixes

    The following important issues are resolved in 8.1.0 (in addition to the dozens of other fixes listed at the end of this post):

    Known issues

    There are no known regressions in this release.

    The following issues may affect people running Drupal 8.1.0 on specific hosting environments:

    • There is not yet per-commit testing for MySQL 5.7.9 or MariaDB 10.1.8 (both released October 2015), but there are no known issues with them. We intend to add per-commit testing on one of these databases in the future.
    • Particular Apache configurations may have issues with serving public file assets. Issue: #2619250: Disabling -MultiViews in .htaccess can cause 500 errors
