#### Accepting multiple changes

If you have multiple changes to accept (and you're sure they ought to be accepted instead of corrected), you can use the `Accept Changes for all Errors` button to speed the process.
This button will cause a Javascript alert dialog to appear asking you to type a reason for accepting the changes, e.g. "Added new API for Gradle 8.x".
