drupal 8.8.0-rc1

This is a release candidate for the next minor version (feature release) of Drupal 8. Release candidates are not supported for production sites, but they are intended for widespread testing in preparation for the upcoming stable release. More information on release candidates.

This minor release candidate provides new improvements and functionality without breaking backward compatibility (BC) for public APIs. 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.

Minor releases may include string changes and additions. Translators can review the latest translation status on localize.drupal.org.

• 8.8.0-alpha1 release notes
• 8.8.0-beta1 release notes

People planning to update to this release should take note of the following important issues:

• All Symfony dependencies have been updated to version 3.4.35.
• 8.8.0-beta1 removed the internal path subscriber and path processor services, which caused an incompatibility with the Pathauto and Subpathauto modules. The services are added back added back for BC in 8.8.0-rc1, which resolves the regression.
• 8.8.0-alpha1 introduced the experimental Claro administrative theme, which uses PostCSS to compile versions of its CSS compatible with all of Drupal 8.8's supported browsers. In that release, the unprocessed CSS was in a src subdirectory, but this subdirectory was in the same directory as the compiled CSS. 8.8.0-rc1 simplifies this directory structure so that the sources and compiled CSS are in the same directory.
