0.1.0.10

    * Added hear primitive as one-shot counterpart to call.  While handle
    may be generally useful for many applications as it fully encapsulates repeated
    handling of incoming requests, hear adds the ability to wait for a single
    incoming request. Hear also returns a function of type Reply suitable for sending
    a single response to the caller. Being more low-level in nature, some applications
    find direct use of hear more flexible than the higher-level handle construct.

    * Fixed a mistake in 0.1.0.9 where RPCs where supposed to have unique identifiers
    for matching up a call with a response.  The value was never computed, when it
    should have been a random value for every call, so that responses could be matched
    with their originating request.  Now using Data.UUID.V4 to generate unique identifiers
    for each request; dependency added in cabal.

    * Unit tests on OS X 10.9 unreliable again, with both ghc 7.6.3 and ghc 7.8.1 (rc1)

    * Unit tests passing on Ubuntu 12.04 LTS AMD64 ghc 7.6.3

    * Unit tests passing on FP Complete with 7.8 preview compiler

0.1.0.9

    * Added HelloWorld example, and updated code sample in documentation to reflect
      working with the current API

    * Early implementation of synchronous RPCs on top of endpoints, with basic unit tests.
      Both single and group RPCs are implemented, as are calls with definite and indefinite
      waits for responses.

    * Removed dependency on network-simple

    * Improved documentation throughout.

0.1.0.8

 * Enabled selective out of order mesage reception, by using a Mailbox, an extension of STM's
   TQueues that extracts the next message from the queue that matches a supplied selection
   function regardless of message order in the queue.

   With selective out of order message reception, endpoints can approximate the
   Erlang-style of message delivery and composing applications that must handle multiple
   message types becomes simpler. If an application needs to handle multiple message types,
   it can choose to run separate separate message pumps concurrently, each handling different
   types of messages. Each message pump can operate independently of one another.

 * Fixed issue #2 and other interim bugs all resulting from multiple name bindings that resolve
   the same underlying address.  Now, bound sockets are reused (with reference counting) so 
   that if there are multiple bindings to the same address only 1 socket is created and user.

 * Unit tests passing on Mac OS X again, mostly due to correct management of sockets and 
   appropriate reuse.
 
0.1.0.7

  * First inclusion of changelog in package
  
0.1.0.6

 * Added simple implementation of transport for UDP
 * Verified build & unit tests on Linux Ubuntu 13.10 with GHC 7.6.3
 * Verified build & unit tests on pre-release GHC 7.8 on FP Complete's platform
 * Mac OS X 10.9 is unreliable for unit tests, do to non-deterministic socket bind failures
