Project: 
Introduced in branch: 
9.2.x
Introduced in version: 
9.2.0-beta1
Description: 

By default, a new Permissions-Policy: interest-cohort=() header is now present. This header is added in response to the implementation of Federated Learning of Cohorts (FLoC), which is a way to gather user data without cookies, regardless of whether a website loads any tracking scripts. As of April 2021, Google's Chrome browser is the only major web browser to implement FLoC.

To disable this header, a new Drupal setting, block_interest_cohort, can be set to FALSE in your settings.php.

Impacts: 
Site builders, administrators, editors
