-SES config for the notification email processor now supports sending an ARN for the SES identity to use when sending an email after the SES SDK V2 update.
+SES config for the notification email processor now supports utilizing an ARN for the SES identity when sending an email after the SES SDK V2 update.
 
-The `sesConfig.fromArn` field is marked as deprecated in favor of `sesConfig.fromEmailAddressIdentityArn` to match the option name passed during the send email command. Currently both `sesConfig.fromArn` and `sesConfig.fromEmailAddressIdentityArn` will set the `fromEmailAddressIdentityArn` option. The `sesConfig.sourceArn` field is removed since no equivalent option is available in the send email command options. Example using `sesConfig.fromEmailAddressIdentityArn`:

The `sesConfig.sourceArn` field is removed since no equivalent option is available in the send email command options. Setting `sesConfig.sourceArn` will have no effect and log a warning. Example changes:
