Note: Test this before going to production. Verify the jquery version being used. If you are using jquery version 1.8 and older, recommend either updating to jquery 1.10 which could cause issues with your other dependencies OR sticking to an older release such as 7.x-1.49. #2113725: Using jQuery Validation Plugin version 1.11.1 or later
This release updates the target of the polyfill from polyfill.io to polyfill-fastly.io. The polyfill.io library has been sold to a chinese company named Funnull that is not considered trustworthy. We believe this poses a grave security threat and the library is now considered unsafe. For more information, see the issue at https://www.drupal.org/project/quicklink/issues/3456671.
