Mir 0.20 has landed in both Xenial and vivid-overlay


  o Allow screencasting to create a virtual output (for Miracast)
  o Separate the protocol version number from the client API version
     macros. They're not meant to be related concepts.
  o Add UBSanitizer to the list of build types.
  o logging: Human readable timestamps in DumbConsoleLogger.
  o examples: AdorningDisplayBufferCompositor::composite() no long
     ignores output boundaries and occlusions.
  o examples: Add -a <app name> option to eglapps.
  o common, client: a more flexible way to probe modules: once we've
     found a good current platform we don't even try to load an older one.
  o Fix build and test run with CMAKE_BUILD_TYPE=ThreadSanitizer.
  o Add MIR_USE_LD_GOLD build option.

Bug fixes:

  o unity-system-compositor crashed with std::runtime_error in
    mir::compositor::CompositingFunctor::wait_until_started() from
    usc::MirScreen::set_screen_power_mode (mir_power_mode_on)
    (LP: #1528384)
  o Phone not usable while a call comes in - followed by "restart"
    (LP: #1532607)
  o ui freezes when simultaneously moving mouse & plug/unplug hdmi
    (LP: #1538632)
  o Mir fails to build on xenial today: android_graphic_buffer_allocator.h
    fatal error: hardware/hardware.h: No such file or directory
    (LP: #1539338)
  o [mali] egl_demo_client_flicker has graphics corruption on android
    (LP: #1517205)
  o [testsfail] Intermittent failure in
    TestClientCursorAPI.cursor_passed_through_nested_server (LP: #1525003)
  o [android] External monitor slows rendering (LP: #1532202)
  o Display::create_gl_context may create context with incorrect attributes
    (LP: #1539268)
  o unity-system-compositor locked up in __libc_do_syscall() (LP: #1543594)
  o NestedServer.client_sees_set_scaling_factor intermittent failure
    (LP: #1537798)
  o [android] External monitor slows rendering - part 2 (LP: #1535894)
  o scene: make sure not to set the swapinterval to 0 when an independent
    stream is created. The default should be 1 (like the stream created as
    part of surface creation).
  o Track the displays plugged state to avoid reporting configurations in
    case they are unplugged (LP #1531503).
  o mouse pointer support on emulator is broken (LP: #1517597).
  o move an android-only test that ended up in tests/unit-tests/graphics.
    (LP: #1546676)
