0.10.0 (Client/Server)

Changed

• Important Possible breaking API change, the original Client has been renamed.

In an attempt to reduce the overhead of managing the project. The original Client has now been revamped to essentially be a synchronous Client over the ClientFuture implementation. The ClientFuture has proven to be a more stable and reliable implementation. It was attempted to make the move seamless, but two new types were introduced, SyncClient and SecureSyncClient, which are both synchronous implementations of the old Client function interfaces. Please read those docs on those new types and the Client trait.

• When EDNS option is present, return only the digest understood matching RRSETs
• All code reformatted with rustfmt
• Important breaking change, all Record and associated types have been migrated to RFC#344 style. get_field() -> field(); field() -> set_field()

Removed
