[ 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:

      simultaneously any more (LP: #1293944)

    . Some mali drivers crash after repeatedly creating/destroying the mir
      compositor threads (LP: #1362841)
