Today SF has just pushed Summer18 (api version 43) to our sandboxes.
And now when our CI process is trying to validate code from branch against empty SF org, it throws bunch of same error messages for each master-Detail field we have in our schema:
Test only deployment cannot insert a new Master-Detail field
Does it mean that in Summer18 we cannot validate code against empty org anymore? Should it already be deployed with some code?
Currently we are using same set of empty orgs to validate different branches, sometimes they even contain inconsistent changes, i.e. permanently deploying to an org is not an option.
Any help/advice would be appreciated

We ran into the same issue and SF support came back with following, its a bummer that validation for codebase which has new master-detail cannot be done anymore.
"We've received multiple cases regarding the same issue; R&D has confirmed that this this error is 'Working as Designed' in the Summer 18 release. The error is only thrown in a check-only deployment, there is no change to regular deployments, so a "proper" deployment should have no issue, unless there is a legitimate error. This check-only error is specific to new Master Detail field. "
