The manual page's description of HSAuthoritativeDir does not specify:
what hidden service descriptor versions such a directory will authoritate,
Version 0 descriptors only.
what versions of Tor produce such descriptors, or
what versions of Tor consume such descriptors.
See the Changelog for 0.2.2.1-alpha:
- Hidden services no longer publish version 0 descriptors, and clients do not request or use version 0 descriptors. However, the old hidden service authorities still accept and serve version 0 descriptors when contacted by older hidden services/clients.
That means 0.2.1.x versions and older produce and consume these descriptors.
It should specify all of those facts (until we're ready to stop documenting the HSAuthoritativeDir option and/or remove it from the Tor sources).
