This is a patch release of Drupal 8 and is ready for use on production sites. Learn more about Drupal 8.
If you are upgrading to this release from 8.7.x, read the Drupal 8.8.0 release notes before upgrading to this release.
This is the final normal bugfix release of 8.8.x. Further bugfixes will be available in 8.9.0 and 9.0.0, also released today. Drupal 8.8.x will receive security coverage until December 2, 2020 when Drupal 9.1.x is released.
If you are running Drupal 8.7.x or earlier, you should update to Drupal 8.8.7 immediately in order to have the latest critical bug and security fixes applied. Sites that wish to receive regular bug fixes should plan to update to Drupal 8.9 in the near future and may consider preparing their site for Drupal 9.
If you are starting a new Drupal project, start with 9.0 for forward compatibility with later releases.
Important update information
Drupal now shows a more user-friendly warning when a site tries to upgrade to a new version without having run required intermediate database updates first.
If you see 'Unsupported schema version' when attempting to run updates, you should:
- Back up your site and codebase.
- Locate an older version of the contributed module which contains the updates you missed.
- Downgrade the module to that version in your code base, and attempt to run updates again.
When this error is shown, it will now also prevent any updates from proceeding, so may make a persistent issue on an existing site more obvious.
Ideally, you should always attempt updates of contributed modules and core on a backup of your site (such as a local development environment) prior to running them on production.
The Views configuration fixes applied as post-updates in #2846614: Incorrect field name is used in views integration for multi-value base fields are now applied at every Views save in order to resolve an upgrade path issue. The old configurations are now formally deprecated in 9.0.0 and will be removed from 10.0.0. For more information on the changes that introduced this in previous releases, see the related change records:
Drupal 9 updates PHPUnit to PHPUnit 8, which introduces backwards compatibility breaks and new deprecations. In order to provide a continuous upgrade path from Drupal 8 (which uses PHPUnit 6 and 7), we've added forward-compatibility shims to provide backwards compatibility and support the new APIs on older PHPUnit versions, and backported them to 8.8.x. Read the change record on the forward-compatibility shims for more information on the methods you can implement in your PHPUnit tests.
A handful of deprecation errors triggered were not actually classified as deprecation errors, and were being raised as silenced notices instead. E_USER_DEPRECATED were added to each to correct the problem. This means a small number of sites or modules might see deprecation errors in their tests when they did not previously. Only a handful of methods are affected. See #3137713: [D8 only] Update deprecation notices in NodeNewComments constructor and #3138591: [D8 only] Add missing E_USER_DEPRECATED to deprecation notices for the affected APIs.
Dependency update information
The project
composer/installersis no longer pinned indrupal/core-recommended. It may now be upgraded whenever a new version is available, and a Composer-managed site runscomposer update. We are releasing this fix on 8.8.x for Composer 2 forward-compatibility and to mitigate against an unusual composer upgrade path problem See #3134648: [backport, needs scheduling] Don't pin the composer/installers version in drupal/core-recommended for background information on this bug, and #3135247: Composer's "prefer-stable" setting cannot be relied on to produce a stable release for the direction we are taking to prevent future such problems.Earlier this year, Symfony released an advisory for a security vulnerabilities, CVE-2019-18888 Drupal core was not affected by these vulnerabilities, so back in November, we updated Drupal's lock file to provide only the secure version of Symfony to tarball installations.
In this release, the version constraint of
symfony/http-foundationhas been increased to 3.4.35, to ensure Composer-built sites are also secure. Going forward, we may adopt this strategy for other packages where Drupal is not affected by a security issue, or we might add an external dependency that adds constraints for insecure versions of packages.Drupal is now using stable releases for behat/mink (1.8.0) and behat/mink-selenium2-driver (1.4.0). While we wouldn't normally do a minor update to dependencies in a patch release, these were previously pinned to development versions because a critical bug affecting Drupal core had not been resolved in any stable release.
This change will also make it easier to transition sites away from
minimum-stability: "dev", which is no longer recommended. (See #3135247: Composer's "prefer-stable" setting cannot be relied on to produce a stable release from the known issues below for more information on our plans to address future issues withminimum-stability.)All of Drupal's JavaScript development packages have been updated to the latest secure versions. This does not affect production sites.
