drupal 8.0.1

This is the first patch release of Drupal 8 and is ready for use on production sites. See the CHANGELOG.txt for an extensive summary of changes and improvements since Drupal 7! Learn more about Drupal 8.

This release only contains bug fixes, as well as documentation and testing improvements.

Known issues

One outstanding critical issue was discovered after the 8.0.0 release but has not been fixed yet. It results in loss of custom configuration translations on multilingual sites under particular circumstances. A fix for this issue will be targeted for a future patch release:

• LocaleConfigManager::updateConfigTranslations() deletes translations if a config object's name happens to match that of a shipped configuration object

The following critical issues were discovered after 8.0.0 but have already been fixed in 8.0.1, as well as dozens of major and minor issues listed below:

• LocaleConfigManager::getTranslatableDefaultConfig() reads config from uninstalled modules
• Configuration of configurable language types reset after module install
• SQL::addWhere not defaulting to "IN" operator when using EntityReferenceView for multiple values
• LocalePluralFormatTest::testPluralEditDateFormatter() is failing randomly

The following issues may affect people running Drupal 8.0.1 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 (expected tomorrow December 3rd).
• 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: Disabling -MultiViews in .htaccess can cause 500 errors
  
• Drupal needs comments in opcache
