---------------
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.
    - Bug fixes:
      . [regression] Mir deb packages with versioned names cannot be installed
        simultaneously any more (LP: #1293944)
      . A frozen client can hang the whole server (LP: #1350207)

      . [regression] Compositing is jerky and stutters during touch events
        (LP: #1372850)

      . TestClientInput.scene_obscure_motion_events_by_stacking fails
        intermittently (LP: #1361757)
      . [regression] First frame is composited as black (even though the client
        has provided a non-black frame) (LP: #1362444)
      . Some mali drivers crash after repeatedly creating/destroying the mir
        compositor threads (LP: #1362841)
      . [android] SIGTERM to server with connected client causes crash
        (LP: #1364637)
      . [regression] acceptance tests fails in
        ServerDisconnect.causes_client_to_terminate_by_default (LP: #1364772)

        /usr/lib/arm-linux-gnueabihf/libmirserver.so.24: undefined symbol:

      . [regression] Mir FTBFS with g++-4.8 [error: ISO C++ forbids casting
        between pointer-to-function and pointer-to-object] (LP: #1366134)
      . Intermittent CI failure in DemoPrivateProtobuf.client_calls_server
        (LP: #1367353)
      . Overly strict libmirplatform* dependencies are blocking CI
        (LP: #1370866)
      . [regression] mir demo servers segfault on shutdown (LP: #1371619)
      . Nested server crashes with SIGSEGV on shutdown in eglDestroyContext()
        (LP: #1372276)
      . [regression] Moving/resizing clients in a nested server is very
        jerky/stuttery (LP: #1372300)
      . [regression] Bypass/overlays are toggling constantly (LP: #1373689)
      . [regression] Mir server uses too much CPU during touch scrolling
