 * (1/17/2018) The `create_domain` command provided by this plugin does not currently update an existing Custom Domain's configuration. Instead, it only supports updating the Route 53 record pointing to the Custom Domain. For example, one must delete and recreate a Custom Domain to migrate it from regional to edge or vice versa, or to modify the certificate.
 * (8/22/2018) Creating a custom domain creates a CloudFront Distribution behind the scenes for fronting your API Gateway. This CloudFront Distribution is managed by AWS and cannot be viewed/managed by you. This is not a bug, but a quirk of how the Custom Domain feature works in API Gateway.
 * (2/12/2019) Users who upgraded from 2.x.x to version 3.0.4 (now unpublished) and then reverted back to 2.x.x will be unable to deploy because of a bug that will be fixed in 3.1.0. The workaround is to delete the basepath mapping manually, which will let them successfully revert back to 2.x.x.
-* (1/20/2022) Using `route53Profile` option requires having hosted zone for the domain in this profile and ACM certificate in the main profile (where functions are deployed).
