drupal 7.81

Maintenance release of the Drupal 7 series. Includes bug fixes and small API/feature improvements only (no major, non-backwards-compatible new functionality).

This release includes various bug fixes and improvements covering diverse areas such as privacy, testing, accessibility, performance and security. The oldest issue marked as fixed in this release was filed in January 2007, four years before D7's first release! Thank you to all contributors for their continued passion, diligence, dedication and good humour.

No changes have been made to robots.txt file in this release, so upgrading custom versions of that file is not necessary.

There are multiple changes in .htaccess, web.config and default.settings.php - please review the notes marked with a * below for details.

Major changes since the last release:

• Permissions-Policy header is added by default to disable a method of browser-based user tracking *
• Drupal 7 testing improvements - new cache and fail-only options
• Backport server configuration code from SA-CORE-2016-003 to Drupal 7 *
