drupal 8.6.15

Maintenance and security release of the Drupal 8 series.

This release fixes security vulnerabilities. Sites are urged to upgrade immediately after reading the notes below and the security announcement:

• Drupal core - Third Party Libraries - SA-CORE-2019-005
• Drupal core - Third Party Libraries - SA-CORE-2019-006

No other fixes are included.

Sites on 8.5.x or earlier should update immediately to Drupal 8.5.15 instead, and plan to update to the latest 8.6.x release before May 1, 2019 (when Drupal 8.7.0 is scheduled for release and 8.5.x security coverage ends).

Important update information

• update.php must be run after updating to ensure changes from the patch take effect.

• No changes have been made to the .htaccess, web.config, robots.txt or default settings.php files in this release, so upgrading custom versions of those files is not necessary if your site is already on the previous release.
