drupal 8.2.6

This is a patch release of Drupal 8 and is ready for use on production sites. Learn more about Drupal 8.

This is also the final scheduled patch release of the 8.2.x series aside from critical or security fixes. The next stable release planned for Drupal 8 will be the Drupal 8.3.0 minor release, which is scheduled for April 5, 2017. Sites should plan to update to 8.3.0 once it is released in order to continue receiving bug and security fixes. An alpha release is available for testing.

This release only contains bug fixes, along with documentation and testing improvements. Translators should take note of a handful of minor string changes since the last release.

The following important issues are resolved in 8.2.6 (in addition to the dozens of other fixes listed at the end of this post):

• Stale dependencies passed to onDependencyRemoval() result in data loss on uninstallation
• Update Symfony components to ~2.8.16 This update was necessary in order to make Drupal 8 compatible with PHP 7.1.
• New JavaScript test methods have been added
• Additionally, the following test failures have been resolved:
  • Postgres fail in Drupal\Tests\path\Kernel\Migrate\d6\MigrateUrlAliasTest
  • Random test failure in DateRangeFieldTest
  • Random fail in CopyFileTest
  • Random Test Failure with "failed to open stream" for temporary://.htaccess
  • Intermittent test fails in LocaleUpdateTest::testUpdateImportSourceRemote()
  • UpdatePathTestBase tests randomly failing

Update instructions

Beginning with 8.2.3, packaged Drupal releases no longer contain development PHP libraries. See Drupal 8 will no longer include dev dependencies in release packages for more information.

Known issues

There are no known regressions in this release.

A recently discovered data loss issue affects this release:

• Bulk operation actions might not act on the selected items

Drupal 8 currently has a number of known issues related to incorrect tracking of file usage, which can result in files being unexpectedly deleted from a site. Site owners experiencing unexplained file loss should consider setting "Delete orphaned files" to "Never" on /admin/config/media/file-system until these issues are resolved, and note the following issues:

• #2801777: Give users the option to prevent Drupal from automatically marking unused files as temporary
• #2708411: File usage not incremented when adding new translation
• #1239558: Deleting a node with revisions does not release file usage
• #2666700: User profile images unexpectedly deleted
• #2810355: Images lost when changing node language

The following issues may affect people running this release on specific hosting environments:

• Windows/IIS environments may encounter site errors due to #2606772: Long Twig cache directories can cause failures on some filesystems
• Particular Apache configurations may have issues with serving public file assets. Issue: #2619250: Disabling -MultiViews in .htaccess can cause 500 errors
