 Feature flagging is a powerful tool, and because it's so powerful, you sometimes need to practice caution. The ability to have complete control over your production environment comes at the cost of the potential to make mistakes in production. Change requests were introduced in version 4.19.0 to alleviate this fear. Change requests allow you to group changes together and apply them to production at the same time, instead of applying changes directly to production. This allows you to make multiple changes to feature toggles and their configuration and status (on/off) all at once, reducing the risk of errors in production.
 
 Our goal is developer effeciency, but we also recognize that we have users and customers in highly regulated industries, governed by law and strict requirements. Therefore, we have added a capability to change requests that will allow you to enforce the _4 eyes principle_.

 ### Circumventing change requests
 
 In the event that you need API access to directly turn something off without going through the change request procedure, you can leverage the skip change request permission. The holder of this permission can bypass the change request procedure and directly change the feature toggle configuration, depending on the other permissions they have. The skip change request permission is only valid for circumventing the change request flow, you still need to explicitly grant the user the permissions for the actions you'd like to perform. IE: Changing a toggle status in an environment, or adding a strategy to a toggle in an environment.
