New Features

• finagle-zipkin-core: Record zipkin.sampling_rate annotation to track sampling rate at trace roots. 2269eb6b

• finagle-core: Added variant of c.t.f.Address.ServiceFactory.apply that does not require specifying c.t.f.Addr.Metadata and defaults to c.t.f.Addr.Metadata.empty. 11971f0f

• finagle-core: Added variant of c.t.f.Name.bound which takes a c.t.f.Service as a parameter. Tying a Name directly to a Service can be extremely useful for testing the functionality of a Finagle client. 1422ffd5

• finagle-mux: Added variant of c.t.f.mux.Request.apply and c.t.f.mux.Requests.make which takes only the body of the Request (in the form of c.t.io.Buf) as a parameter. This is useful for when the path value of a Request is not used by the server (e.g. testing). 3ca46304

Runtime Behavior Changes

• finagle-memcached: The log level of messages pertaining to whether a Memcached client is using the older non-partitioned or the newer partitioned version has been lowered. These messages are no longer written at an 'info' level. 4bce560a
