This release fixes critical security vulnerabilities. Sites are urged to upgrade immediately after reading the notes below and the security announcement:
Drupal core - Critical - Remote Code Execution - SA-CORE-2018-004
No other fixes are included.
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.
