Breaking API Changes
- finagle-core: Deprecated multi-param legacy tls methods have been removed in c.t.f.param.ServerTransportParams and c.t.f.builder.ServerBuilder. Users should migrate to using the tls(SslServerConfiguration) method instead. ca646bd8

Twitter Server
- Change the /admin/histograms?h=…-style endpoints to return data in the same style as /admin/histograms.json. This should make it easier to use tools to parse data from either endpoint. 92e4dad5
