Known issues

There are no known critical issues with this release. Search the issue queue for all known issues.

The following issues may affect people running Drupal 8.0.0 on specific hosting environments:

• Installs on php-fpm environments may see fatal errors on enabling modules, due to #2572293: Do not rebuild router in kernel.terminate.
• While PHP 7 does not yet have a stable release, Drupal 8.0.x is now tested on every commit with PHP 5.5, 5.6 and 7 with a 100% pass rate, so should support PHP 7’s first stable release once it is available.
• There is not yet per-commit testing for MySQL 5.7.9 or MariaDB 10.1.8 (both released October 2015), but a minor incompatibility issue was fixed since RC4, and there are no known issues with them otherwise. We intend to add per-commit testing on one of these databases soon.
• Particular Apache configurations may have issues with serving public file assets. Issue: #2619250: Remove symlinks option from .htaccess

Changes since 8.0.0-rc4

A small number of minor backward-compatibility breaks have been introduced since RC4 to resolve two major bugs before release:

• Views no longer uses fields on base tables when they also exists on the data table to resolve a promient bug in the Views UI. This update requires module-provided default views to be re-exported.
• A new ContentEntityStorageInterface and hook_entity_field_values_init() and hook_entity_translation_create() have been added to replace cases where hook_entity_create() was used for cases other than creating new entities. hook_entity_create() is no longer called in those cases. This prevents unintended data issues from being introduced by modules written on monolingual sites.

As of 8.0.0, we will be following semantic versioning for future releases. Patch releases should not contain any API additions or deprecations. Minor versions may add new deprecations with backwards compatibility layers or change code marked @internal. See draft documentation for the Drupal 8 backwards compatibility policy and
the policy on Allowed changed during the Drupal 8 release.
