Maintenance release of the Drupal 7 series.
This release includes a single bug fix to address a regression with drag-and-drop behavior that was introduced in Drupal 7.51 (and persisted in Drupal 7.52) for certain web browsers and certain jQuery versions.
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.
Known issues:
There are no known regressions in this release.
