Hi, I would like to know the github name of "armin K". I don't find him and
would like to read the changes made to touchpad acceleration and Weston.ini
Thanks

> Wayland Changes
>
> We don't have a lot of Wayland side changes this time. I see that as
> good news and as sign that the wayland side is slowing down and
> maturing. I feel like the core protocol code is generally useful and
> stable and does what we need. What we did do this cycle:
>
> - More pixel formats for wl_shm (Tomeu Vizoso). We can now create
> RGB565 (and many more) shm surfaces and a compositor can indicate
> which ones it supports.
>
> - Doc work (Peter Hutterer, Bryce Harrington, Aaron Faanes). Much
> work on the doc build system from Peter and general wording and
> grammer improvements all around.
>
> - Multi resource support (Rob Bradford). Rob added support for
> dealing with lsits of resources which the weston side
> multi-resource fix builds on.
>
> - Support for language bindings (Jason Ekstrand). After a long time
> and many detours into fixing other parts of Wayland and Weston,
> Jason finally landed the language binding support. This feature
> lets you bind a higher level language to libwayland-client/server
> by providing custom dispatch functions.
>
> - Release requests for wl_pointer, wl_keyboard and wl_touch (Rob
> Bradford). We don't have a way for a client to deregister its
> interest in receiving input events, we just drop them on the client
> side when the client destroys the proxy. With the release
> requests, we now have a way to stop the server from sending them in
> the first place.
>
> - Install the wayland.xml protocol defintion (Jason Ekstrand). We
> now install the core Wayland XML protocol definition in a public
> location. Language bindings can parse this to generate code or
> bind dynamically. This also introduces a well known protocol
> directory where other projects can install protocol files.
>
> - Very few bug fixes in this release. There was only a couple of
> actual bug fixes this time around, which again is a sign that core
> wayland is settling down.
>
>
> Weston changes.
>
> - HW accelerated screen capture using libva Shift-Mod-SPACE Q (Ander
> Conselvan de Oliveira). This adds realtime h.264 screen capture to
> Weston using libva. This new feature can capture and encode weston
> screen contents and write to disk with negligible CPU or GPU
> overhead on recent Intel chips. We may switch away from libva and
> use gstreamer in the future, which will let us support more codecs
> and hardware. For now, libva is the only way to get to the
> high-performance, zero-copy encoding path that we want. Another
> future direction for this is network astreaming instead of just
> writing to disk, but this basic recording feature wil be the base
> for that work.
>
> - libhybris support (Adrian Negreanu). Adrian added support for
> using libhybris with the fbdev backend. This means that it's
> possible to use weston with Android EGL/GLES2 drivers, provided
> that you have the right device, drivers and kernel.
>
> - Multi-resource input events (Rob Bradford and Neil Roberts). We
> had a limitation that only the first pointer, keyboard or touch
> resource from a client would receive events, since we only tracked
> one resource as part of the input focus tracking. It should be
> possible to get multiple wl_pointer etc resources and receive
> events on all of them so that different subsystems can have their
> own resource for receiving events. With Rob and Neils patches this
> now works, which enables toolkit integration such as WebKitGTK+ and
> Clutter-GTK+.
>
> - Better touch support: better support in clients (Rusty Lynch and
> Brian Lovin), critical bug fixes in the evdev touch code (Neil Roberts).
>
> - XWM: better fullscreen support, support for drag-and-drop from X to
> wayland (other direction coming next). (Kristian Høgsberg)
>
> - weston-launch: modified behavior, now two modes of
> operation: run from a vt after logging in or run from an init
> script with -u. setup and restore tty in weston-launch, handle vt
> switch and drop/set master in weston-launch (Kristian Høgsberg).
>
> - Support for RGB565 client buffers in gl and pixman renderers
> (Tomeu Vizoso).
>
> - New WL_OUTPUT udev attribute for matching touch screen input
> devices to their outputs. (krh)
>
> - We have a new configure summary from Armin K and a few new
> configure options:
>
> --with-cairo=image/gl/glesv2
>
> This gives better control over which cairo-gl flavor
> to use. We used to auto-detect or just fall back to
> image, but there was never a good way to request
> cairo-image if any cairo-gl was available or to
> request GL over GLES2. (Rob Bradford)
>
> --enable-demo-clients
>
> Install all the demo clients. Normally we only
> install weston-terminal and weston-info, but with this
> option it's now possible to install all clients (Armin k)
>
> - New weston.ini options:
>
> [touchpad]
> constant_accel_factor=...
> min_accel_factor=...
> max_accel_factor=...
>
> These options lets us control touchpad acceleration
> (Armin K).
>
> [xwayland]
> path=...
>
> This option lets us specific a different path to the
> xwayland server to use (Maksim Melnikau).
>
> - New weston command line options:
>
> --shell=shell.so
>
> Override the shell module choice from weston.ini. A
> useful option for briefly testing a different shell
> (Jason Ekstrand).
>
> - weston-terminal: Better support for wide (CJK) characters (Peng
> Wu). Resizing fixed, warms my heart (José Bollo).

>
> Known Issues
>
> We're shipping the 1.3.0 release with a number of known issues. I
> expect we'll do a 1.3.1 release within a couple of week to try to fix
> as many of these as possible. This is Arties list from the RC2 test
> report:
>
> - weston-launch grew a drm dep again, pull Tomeus fix.
>
> - Fix desktop-shell resizing the right way. I reverted Hardenings
> patch for output resize in desktop-shell to avoid regressing output
> rotation, but we need to fix it the right way.
>
> - Rapid VT-switching causes hang
> <https://bugs.freedesktop.org/show_bug.cgi?id=69764>
>
> - Multiple mouse cursors on a single seat with multi-seat setup:
> <https://bugs.freedesktop.org/show_bug.cgi?id=69778>
>
> - Weston SEGV on hot-unplugged output:
> <https://bugs.freedesktop.org/show_bug.cgi?id=69777>
>
> - Weston-calibrator always uses "primary" output; bad for
> multi-display calibration:
> <https://bugs.freedesktop.org/show_bug.cgi?id=69780>
>
> - Zoom and Touch don't play nice with each other:
> <https://bugs.freedesktop.org/show_bug.cgi?id=68620>
>
> - Weston SEGV - Text input protocol post to dying resource:
> <https://bugs.freedesktop.org/show_bug.cgi?id=69490>
>
> - Weston-terminal corrupt rendering when output transformed at 90 or 270:
> <https://bugs.freedesktop.org/show_bug.cgi?id=70250>
>
> with a couple of bugs outside wayland and weston that still affects
> key weston features:
>
> - Composite Bypass non-functional:
> <https://bugs.freedesktop.org/show_bug.cgi?id=69437>
>
> - LibVA Capture hangs Weston on Sandy Bridge platforms:
> <https://bugs.freedesktop.org/show_bug.cgi?id=69330>

> Ideally we'll be able to address many of the issues above, in

> desktop-shell resizing and the output unplug bugs before doing 1.3.1.

> Plans for 1.4
>
> We're going to try something new for 1.4 - we'll do an alpha release a
> month before the scheduled release. I'm looking at Jan 15, 2014 as
> the release date for 1.4.0, and we'll do an alpha release on Dec 16.
> The motivation here is to get a snapshot out a bit earlier so we can
> start testing earlier and hopefully uncover bugs earlier. In the 1.3
> cycle we did RC1 a week before the expected release date and ended up
> with a lot of bugs and no time to fix them. For 1.4 the hope is that
> the alpha release will let us discover those bugs while we still have
> month to fix them. After the alpha we'll start to slow down
> development, but there'll still be room for pulling in minor or
> low-risk features. We'll start the RCs on Jan 2, at which point we'll
> go into bug fix only mode.
>
> Here's my (probably incomplete) list of features that I think we can
> do for 1.4:
>
> - Moving subsurface and input methods into wayland.
>
> - Jasons decorations work.
>
> - Jasons surface/view split.
>
> - logind changes from David.
>
> - Output cloning
>
> - wl_shm buffer truncate exploit fix from Neil
>
> - eglSwapInterval(0) (Neil)
>
> - Nested wl_buffer pass-through (Neil)
>
> - Touch grabs to enable touch-to-focus (Neil)
>
> - Default pointer grab patch from Giulio
>
> - Use gstreamer or libva helper library instead of direct
> libva use for weston encoding.
>
> - wl_subsurface scaling.
