Publishing apps on custom domains
Retool now supports publishing apps on custom domains. If you self-host Retool (which inherently uses a custom domain) or use a custom domain on a cloud instance, your apps are published to the domain you define in the following format: https://example.retool.com/rr/app/<appName>.
If your organization uses custom domains, previously-published apps should be republished in order to serve them from the appropriate domain.
Apps published on custom domains are subject to an additional set of limitations that are applied because Retool runs your app inside a sandboxed iframe with allow-same-origin disabled.
This change applies only to apps created using the new app builder.
