Along with several other changes, such as renaming caddyhttp.ServerRoute to caddyhttp.Route, exporting some types that were not exported before, and tweaking the caddytls TLS values to be more consistent. Notably, we also now disable automatic cert management for names which already have a cert (manually) loaded into the cache. These names no longer need to be specified in the "skip_certificates" field of the automatic HTTPS config, because they will be skipped automatically.
