[ 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)
    . QtMir FTBFS: fatal error: mir/input/input_channel.h: No such file or
      directory (LP: #1365934)
    . [regression] platform-api fails to build against Mir 0.8 (LP: #1368354)
    . Mir FTBFS with gcc 4.9.1-14 (utopic update):
      auto_unblock_thread.h:44:46: error: no matching function for call to
      ‘std::thread::thread(<brace-enclosed initializer list>)’ (LP: #1369389)
    . [regression] Compositing is jerky and stutters during touch events
      (LP: #1372850)
    . unit test fails: AndroidInputReceiverSetup.slow_raw_input_doesnt_cause_
      frameskipping (LP: #1373826)
    . intermittent hang in TestClientInput (LP: #1338612)
    . 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)
    . [regression] symbol lookup error:
      /usr/lib/arm-linux-gnueabihf/libmirserver.so.24: undefined symbol:
      _ZTIN7android7RefBaseE (libmirserver 0.6.1 doesn't work with
      libmircommon 0.7.0) (LP: #1364890)
    . [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
      (LP: #1373809)
    . Intermittent test failures in TestClientCursorAPI.* (LP: #1342567)
    . clang emits lots of warnings about lttng headers (LP: #1348472)
    . [enhancement] Draw input event location (LP: #1323522)
    . demo shell: Keep colours consistent, regardless of the physical pixel
      format of your framebuffer (LP: #1375660)
    . tests: Fix SharedLibraryProber test runs on i386. (LP: #1375829)
    . Touchspots rendered as squares on some devices (LP: #1373698)
    . The headers needed to use features shown in the acceptance tests are
      not published (LP: #1375301)
    . update-all-ABI-sha1sums.sh and install_on_android.sh are no longer
      executable. (LP: #1376547)
    . Fix arm64 package by adding arm64 to the shared library prober test.
      (LP: #1379478)
