Release Notes: This is a maintenance release. It includes bugfixes and small API/feature improvements only (no major new functionality); significant new features are only being added to the forthcoming Drupal 8.0 release. No security fixes are included in this release. Besides documentation fixes, no changes have been made to the .htaccess, robots.txt, or settings.php files in this release, so upgrading custom versions of those files is not necessary.
Release Notes: Reverses a patch for validating email addresses with a trailing period, fixes a theme error when using drush, and fixes a locale module upgrade error.
