v3.6.24

• Updated dependencies for compatibility with Node.js 4.
• Changes the default for peer selection: now uses a heap to choose peers for outbound requests. This can be configured with the choosePeerWithHeap TChannel option.
• Addresses a problem in lazy relay, which would read the response flags instead of the response code, confusing stats.
• Adds support for tryConnect() on peers, with back-off.
• Ensures a minimum number of connections for each peer. The intent is to eventually support a connections count goal.
• Fixes a bug in the HTTP argument scheme regarding the Content-Length header.
• Removes the special cases for the "self" peer. These interfaces have been removed. External usage of these private interfaces is not expected.
• Numerous performance improvements, particularly using object pooling and lazy buffer slicing.

Hyperbahn:

• Adds a Hyperbahn::discover method to the Hyperbahn client, suitable for querying available peers for a given service.
• Now emits stats for error frames produced and forwarded.

Thrift:

• Relaxes the constraint that application exeptions in the Thrift arg scheme must be instances of the JavaScript Error base type.
• The Thrift argument scheme instance now exposes a getServiceEndpoints method for introspecting methods.
• ThriftRW upgraded to version 3.4.3, capturing fixes for lists of lists, and maps with integer keys, and adds support for the i8 alias for the byte type.
