Maintenance and security release of the Drupal 7 series.
This release fixes highly critical security vulnerabilities. Sites are urged to upgrade immediately after reading the notes below and the security announcement:
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.
As of this release, Drupal strips out several potentially dangerous values from user-provided input. This is unlikely to break sites because the values that are stripped are very rarely used intentionally.
