  [ Daniel van Vugt ]
  * New upstream release 0.16.0 (https://launchpad.net/mir/+milestone/0.16.0)
    - ABI summary: Only servers and graphics drivers need rebuilding;
      . Mirclient ABI unchanged at 9
      . Mirserver ABI bumped to 34
      . Mircommon ABI unchanged at 5
      . Mirplatform ABI bumped to 10
      . Mirprotobuf ABI bumped to 2
      . Mirplatformgraphics ABI bumped to 5
      . Mirclientplatform ABI unchanged at 3
    - Enhancements:
      . Significantly shortened buffer holding time for system compositors
        should yield higher/smoother frame rates.
      . Progress on new buffer semantics work.
      . Mir-on-x platform refinements, including support for guest platform,
        key combinations, rotation, display window size.
      . Enhanced cross-compilation, including multi-distro, and multi-arch
        support.
      . Added message auth code to make_event functions. Older implementations
        are now marked as deprecated.
      . Added EventBuilder for input platforms to use to construct events.
      . Improved logging.
      . Added protobuf versioning support.
      . Support for the NATIVE_WINDOW_CONSUMER_USAGE_BITS query.
      . Added utilities to detect the capabilities of an input device.
      . Initial refactoring to support renderers other than GL.

Title:
  [regression] Intermittent test failure
  BufferQueue/WithThreeOrMoreBuffers.queue_size_scales_with_client_performance

Status in Mir:
  Fix Committed

  Fix Released

Bug description:
  CI run failure in this branch:
  https://code.launchpad.net/~brandontschaefer/mir/msg-auth-code-field-added/+merge/268383

  Though this branch doesnt touch anything around those parts, so most
  likely a separate intermittent failure.

  Value of: buffers_acquired.size()
  Expected: is equal to 2
  Actual: 3 (of type unsigned long)
  [ FAILED ] BufferQueue/WithThreeOrMoreBuffers.queue_size_scales_with_client_performance/0, where GetParam() = 3 (405 ms)
