New Features

• finagle-core: Introduce Dtab.limited, which is a process-local Dtab that will NOT be remotely broadcast for any protocol, where Dtab.local will be broadcast for propagation on supported protocols. For path name resolution, the Dtab.local will take precedence over the Dtab.limited, if the same path is defined in both, and both take precedence over the Dtab.base. The existing Dtab.local request propagation behavior remains unchanged. 2e06c669
• finagle-core: Add descriptions to RequestDraining, PrepFactory, PrepConn, and protoTracing modules in StackClient. Add descriptions to preparer and protoTracing modules in StackServer. 1ea1a3eb

Breaking API Changes

• finagle-memcached: Ketama Partitioned Client has been removed and the Partition Aware Memcached Client has been made the default. As part of this change, com.twitter.finagle.memcached.UsePartitioningMemcachedClient toggle has been removed, and it no longer applies. 2628b84b

Runtime Behavior Changes

• finagle-core: Broadcast context keys lookups are now case insensitive. This change is backwards compatible as the marshalled key id is unchanged. Although enabled by default, this change will be temporarily sitting behind a toggle, com.twitter.finagle.context.MarshalledContextLookupId that can be used to turn off this change. 69c29093

Deprecations

• finagle-core: The ServerBuilder pattern has been deprecated. Use the stack server pattern instead. 386171ad
