From the Tempest point of view, there is no difference between deprecated vs non-deprecated APIs, we keep testing it until those are not removed. For example, you can still run Tempest for Cinder v2 APIs.

Sorry for the delay. To my knowledge, no one on the Swift team has added or deprecated any Tempest tests. Some more specific details about recent

The new object versioning APIs affect both Swift and S3 access. For more information about the new Swift versioning API, see https://docs.openstack.org/swift/latest/middleware.html#object-versioning. 
For more information about the S3 versioning API, see https://docs.aws.amazon.com/AmazonS3/latest/dev/Versioning.html; we've reproduced the S3 behaviors as faithfully as we could and any differences should be reported as bugs.

I don't know what expectations Tempest has around ETags; it may be that no changes are warranted even if the service defaults to RFC-compliant ETags. At any rate, the default ETag quoting behavior is unlikely to change in the near future (measured in years).

I'm not sure that USR1 signal handling would really be in-scope for Tempest. I was under the impression that Tempest was performing blackbox testing (and so would not deal with service management issues), though I'd welcome any corrections in my understanding.

Along the same lines, swift-ring-builder seems out of scope as well.

The auto_create_account_prefix change should not change any client-facing behaviors; rather, it simply moved a config option to a more suitable location.
