* Under development
* New upstream release 0.4.0 (https://launchpad.net/mir/+milestone/0.4.0)
- mirclient ABI bumped to 8. Clients need rebuilding.
. Add surface attribute for visibility.
. Add surface orientation API.
- mirserver ABI bumped to 22. Shells need rebuilding.
. Allow setting the orientation of a server surface.
. Change compositor::Scene to expose compositor::SceneElements instead
of graphics::Renderables.
. Change various input and Surface classes to support the client cursor
API.
. Support unregistering fd handlers in the EventHandlerRegister and
related interfaces (MainLoop).
. server: Change mc::Scene to deal in mc::SceneElements instead of
mg::Renderables.
. Add visibility tracking to mc::SceneElement interface and
implementations.
. Unregister FD Handler from EventHandlerRegister.
. Sending user input events through Surfaces.
. Move InputChannelFactory into DefaultServerConfiguration.
. Ensure default input region is updated when surface is resized. (LP: #1332632)
- android: support alpha blending overlays together in HWC. Bumps
android-headers version requirement from 4.2.2 to 4.4.2. (LP: #1329879)
- android: designate the buffer usage when attempting to access or
update the fence associated with the native buffer. (LP: #1329868)
- Enable client cursor API.
- Enable support for USB touchscreens.
- Various test improvements.
- Ensure the_cursor() is not null. (LP: #1334010)

* New upstream release 0.3.0 (https://launchpad.net/mir/+milestone/0.3.0)
- mirclient ABI unchanged, still at 7. Clients do not need rebuilding.
- mirserver ABI bumped to 21. Shells need rebuilding.
. Divide swap_client_buffers into separate functions.
. Allow buffer swapping even when compositor is turned off or blocked.
(LP: #1308843, 1308844)
. Wire the cursor client API through the session mediator to the surface
observer.
. Generate destination alpha for alpha enabled display buffers.
. Named threads.
. Support for prompt sessions :
https://wiki.ubuntu.com/Security/TrustStoreAndSessions.
- mirscreencast screenshots now produce images with correct color instead
of transparency.
- Rename bind_to_texture->gl_bind_to_texture.
- Refinements in test infrastructure.
- Phablet: allow disabling the overlays via a command line switch.
- Unify the DisplayBuffer interface's optimization functions
behind post_renderables_if_optimizable.
- Clean up the DisplayDevice interface so that it doesn't require the
functions are called in any particular order.
- Phablet: graphics: android: preserve buffer ownership for onscreen
overlay layers until the subsequent display posting.
- Allow the platform to register emergency cleanup handlers in order to
restore the graphics system to a sane state when the server fails
abruptly.
- Bugs fixed:
. Mirscreencast outputs translucency instead of shadows, producing
incorrect images. (LP: #1301210)
. JSON formatting. (LP: #1324902)
. Fix input_area_contains to work properly in global coordinates even
when input_rectangles is updated. (LP: #1261647)
. Allow a moment for clients to acquire a buffer. (LP: #1317370)
. Generate correct alpha by changing blending equation to assume
pre-multiplied alpha sources. (LP: #1318852)
. Rework the recomposition messaging so that the DisplayBufferCompositor
is no longer involved. (LP: #1319907)

* New rebuild forced
[ Daniel van Vugt ]
- mirserver ABI bumped to 20. Shells need rebuilding.
. Added default implementation for SceneObserver.
. Surface no longer implements Renderable, but emits one via
. Pass the full renderable list to Renderer::render().
. Graceful handling of exceptions thrown from server threads.
. Clarify size position interfaces in the Surface classes.
. Plumbing for trusted sessions.
. Allow posting and managing custom main-loop actions.
. Timer extension.
. Identify client process when client connects to Mir not when socket
connects.
. Use the ServerActionQueue for display config.
. Recomposition signal moved to the MultiThreadedCompositor.
. Make timer service replaceable.
. Clarify assumptions about how many buffers a client can fill without
blocking.
. Introduce EmergencyCleanup interface.
. New shell controls documented.
- A new testing category, performance test, was introduced. It currently
runs glmark2-es2 and compares the result to a minimum threshold.
- MIR_VERSION_MINOR is tied to MIRSERVER_ABI in the sense that a change
in the former now requires dependent projects that a rebuild is
necessary.
- SwitchingBundle was replaced by BufferQueue.
- Replaced uses of android::sp with std::shared_ptr.
- Client cursor API infrastructure.
- Enabled eglSwapInternal(0).
- Make texture caching algorithm reuseable.
- Add a DPI surface attribute.
- Exclude arm64 from build.

(LP: #1315302)
. [regression] Enabling SwitchingBundleTest
DISABLED_synchronous_clients_only_get_two_real_buffers now crashes with
