mir (0.8.0+14.10.20141010-0ubuntu1) utopic; urgency=medium

  [ Daniel van Vugt ]
  * New upstream release 0.8.0 (https://launchpad.net/mir/+milestone/0.8.0)
    - Enhancements:
      . Less sensitivity to ABI breaks - many headers unused by external
        projects are now hidden and not installed by -dev packaes. If you
        require any headers that are missing, just ask.
      . Touchspots: --enable-touchspots to servers; visually shows touch
        locations (warning: This affects performance LP: #1373692).
      . Client performance reporting: Any Mir client can now get accurate
        performance information (frame rate, render time, buffer lag etc)
        logged to stdout. Just set env MIR_CLIENT_PERF_REPORT=log
      . Further improved touch responsiveness, with less lag and smoother
        scrolling (so long as you don't enable touchspots).
      . Slightly faster builds using precompiled headers.
      . Turn hardware overlays on by default. When in use, this halves the
        CPU usage of a Mir server. Already enabled in unity-system-compositor.
      . More scripting to detect ABI breaks.
      . Improved src/ tree consistency (renamed "src/shared" to "src/common").
      . Improved fatal signal design: Changed from SIGTERM to SIGHUP delivered
        to clients on unexpected server disconnection.
      . Improved library/package design to allow concurrent installations
        of different Mir versions without conflicts.
      . Fd reception code is now common to client and server.
    - ABI summary: Servers need rebuilding, but clients do not;
      . Mirclient ABI unchanged at 8
      . Mircommon ABI bumped to 2
      . Mirplatform ABI bumped to 3
      . Mirserver ABI bumped to 26
    - API changes between Mir 0.7 and 0.8:
      . Lots of headers removed from the public SDK! We have only hidden
        headers not known to be used by any known projects. Please let us
        know if anything is missing - https://bugs.launchpad.net/mir/+filebug
      . graphics::Platform - interface changed significantly.
      . Lots of server API changes to support touchspots.
      . File descriptors now passed as type Fd instead of int32_t.

  intermittent hang in TestClientInput

Bug description:
  Only see once and not reproduced since. I was testing issues with
  concurrent tests and so don't have complete information about this
  occurrence. I have a test instance hung  with the call stack:

  #0  0x00007fc0ec75d66b in pthread_join (threadid=140466456983296, thread_return=0x0) at pthread_join.c:92
  #1  0x00007fc0ebc729e7 in std::thread::join() () from /usr/lib/x86_64-linux-gnu/libstdc++.so.6
  #2  0x00000000006c5f24 in tear_down (this=0x14ace08) at /home/alan/display_server/mir1/tests/acceptance-tests/test_client_input.cpp:101
  #3  (anonymous namespace)::TestClientInput::TearDown (this=0x14ac7a0)
      at /home/alan/display_server/mir1/tests/acceptance-tests/test_client_input.cpp:145

  It looks like this is teardown from
  TestClientInput.multiple_clients_receive_motion_inside_windows as I
  see that start and not finish on the console.
