 ::
 
+ 1.17   - add MPV_FORMAT_BYTE_ARRAY
+ --- mpv 0.9.0 will be released ---
+ 1.16   - add mpv_opengl_cb_report_flip()
+        - introduce mpv_opengl_cb_draw() and deprecate mpv_opengl_cb_render()
+ 1.15   - mpv_initialize() will now load config files. This requires setting
+          the "config" and "config-dir" options. In particular, it will load
+          mpv.conf.
+        - minor backwards-compatible change to the "seek" and "screenshot"
+          commands (new flag syntax, old additional args deprecated)
+ --- mpv 0.8.0 is released ---
+ 1.14   - add mpv_wait_async_requests()
+        - the --msg-level option changes its native type from a flat string to
+          a key-value list (setting/reading the option as string still works)
+ 1.13   - add MPV_EVENT_QUEUE_OVERFLOW
+ 1.12   - add class Handle to qthelper.hpp
+        - improve opengl_cb.h API uninitialization behavior, and fix the qml
+          example
+        - add mpv_create_client() function
+ 1.11   - add OpenGL rendering interop API - allows an application to combine
+          its own and mpv's OpenGL rendering
+          Warning: this API is not stable yet - anything in opengl_cb.h might
+                   be changed in completely incompatible ways in minor API bumps
+ --- mpv 0.7.0 is released ---
  1.10   - deprecate/disable everything directly related to script_dispatch
           (most likely affects nobody)
  1.9    - add enum mpv_end_file_reason for mpv_event_end_file.reason

+Client API examples
+===================
+
+All these examples use the mpv client API through libmpv.
+
+cocoa
+-----
+
+Shows how to embed the mpv video window in Objective-C/Cocoa.
+
+qt
+--
+
+Shows how to embed the mpv video window in Qt (using normal desktop widgets).
+
+qml
+---
+
+Shows how to use mpv's OpenGL video renderer in QtQuick2 with QML.
+
+qml_direct
+----------
+
+Alternative example, which typically avoids a FBO indirection. Might be
+slightly faster, but is less flexible and harder to use.
+
+simple
+------
+
+Very primitive terminal-only example. Shows some most basic API usage.

+Compiling for Windows
+=====================
+
+Compiling for Windows is supported with MinGW-w64. This can be used to produce
+both 32-bit and 64-bit executables, and it works for building on Windows and
+cross-compiling from Linux and Cygwin. MinGW-w64 is available from:
+http://mingw-w64.sourceforge.net.
+
+While building a complete MinGW-w64 toolchain yourself is possible, there are a
+few build environments and scripts to help ease the process, such as MSYS2 and
+MXE. Note that MinGW environments included in Linux distributions are often
+broken, outdated and useless, and usually don't use MinGW-w64.
+
+**Warning**: the original MinGW (http://www.mingw.org) is unsupported.
+
+Cross-compilation
+=================
+
+When cross-compiling, you have to run mpv's configure with these arguments:
+
+```bash
+DEST_OS=win32 TARGET=i686-w64-mingw32 ./waf configure
+```
+
+[MXE](http://mxe.cc) makes it very easy to bootstrap a complete MingGW-w64
+environment from a Linux machine. See a working example below.
+
+Alternatively, you can try [mingw-w64-cmake](https://github.com/lachs0r/mingw-w64-cmake),
+which bootstraps a MinGW-w64 environment and builds mpv and dependencies.
+
+Example with MXE
+----------------
+
+```bash
+# Before starting, make sure you install MXE prerequisites. MXE will download
+# and build all target dependencies, but no host dependencies. For example,
+# you need a working compiler, or MXE can't build the crosscompiler.
+#
+# Refer to
+#
+#    http://mxe.cc/#requirements
+#
+# Scroll down for disto/OS-specific instructions to install them.
+
+# Download MXE. Note that compiling the required packages requires about 1.4 GB
+# or more!
+
+cd /opt
+git clone https://github.com/mxe/mxe mxe
+cd mxe
+
+# Set build options.
+
+# The JOBS environment variable controls threads to use when building. DO NOT
+# use the regular `make -j4` option with MXE as it will slow down the build.
+# Alternatively, you can set this in the make command by appending "JOBS=4"
+# to the end of command:
+echo "JOBS := 4" >> settings.mk
+
+# The MXE_TARGET environment variable builds MinGW-w64 for 32 bit targets.
+# Alternatively, you can specify this in the make command by appending
+# "MXE_TARGETS=i686-w64-mingw32" to the end of command:
+echo "MXE_TARGETS := i686-w64-mingw32.static" >> settings.mk
+
+# If you want to build 64 bit version, use this:
+# echo "MXE_TARGETS := x86_64-w64-mingw32.static" >> settings.mk
+
+# Build required packages. The following provide a minimum required to build
+# a reasonable mpv binary (though not an absolute minimum).
+
+make gcc ffmpeg libass jpeg pthreads lua
+
+# Add MXE binaries to $PATH
+export PATH=/opt/mxe/usr/bin/:$PATH
+
+# Build mpv. The target will be used to automatically select the name of the
+# build tools involved (e.g. it will use i686-w64-mingw32.static-gcc).
+
+cd ..
+git clone https://github.com/mpv-player/mpv.git
+cd mpv
+python ./bootstrap.py
+DEST_OS=win32 TARGET=i686-w64-mingw32.static ./waf configure
+# Or, if 64 bit version,
+# DEST_OS=win32 TARGET=x86_64-w64-mingw32.static ./waf configure
+./waf build
+```
+
+Native compilation with MSYS2
+=============================
+
+For Windows developers looking to get started quickly, MSYS2 can be used to
+compile mpv natively on a Windows machine. The MSYS2 repositories have binary
+packages for most of mpv's dependencies, so the process should only involve
+building mpv itself.
+
+To build 64-bit mpv on Windows:
+
+Installing MSYS2
+----------------
+
+1. Download an installer from https://msys2.github.io/
+
+   It doesn't matter whether the i686 or the x86_64 version is used. Both can
+   build 32-bit and 64-bit binaries when running on a 64-bit version of Windows.
+
+2. Add ``C:\msys64\mingw64\bin`` to your ``%PATH%``. mpv will depend on several
+   DLLs in this folder.
+
+3. Start a MinGW-w64 shell (``mingw64_shell.bat``). For a 32-bit build, use
+   ``mingw32_shell.bat``.
+
+Updating MSYS2
+--------------
+
+To prevent errors during post-install, ``msys2-runtime`` and ``pacman`` must be
+updated first.
+
+```bash
+# Check for updates to msys2-runtime and pacman. If there were updates, restart
+# MSYS2 before continuing.
+pacman -Sy --needed msys2-runtime pacman
+
+# Update everything else
+pacman -Su
+```
+
+Installing mpv dependencies
+---------------------------
+
+```bash
+# Install MSYS2 build dependencies and a MinGW-w64 compiler
+pacman -S git pkg-config python3 mingw-w64-x86_64-gcc
+
+# Install the most important MinGW-w64 dependencies. libass, libbluray and
+# lcms2 are also pulled in as dependencies of ffmpeg.
+pacman -S mingw-w64-x86_64-ffmpeg mingw-w64-x86_64-libjpeg-turbo mingw-w64-x86_64-lua
+
+# Install additional (optional) dependencies
+pacman -S mingw-w64-x86_64-libdvdnav mingw-w64-x86_64-mpg123 mingw-w64-x86_64-libguess
+```
+
+For a 32-bit build, install ``mingw-w64-i686-*`` packages instead.
+
+Building mpv
+------------
+
+Clone the latest mpv from git and install waf:
+
+```bash
+git clone https://github.com/mpv-player/mpv.git && cd mpv
+./bootstrap.py
+```
+
+Finally, compile and install mpv. Binaries will be installed to
+``/mingw64/bin``.
+
+```bash
+# For a 32-bit build, use --prefix=/mingw32 instead
+./waf configure CC=gcc --prefix=/mingw64
+./waf install
+```
+
+Or, compile and install both libmpv and mpv:
+
+```bash
+./waf configure CC=gcc --enable-libmpv-shared --prefix=/mingw64
+./waf install
+
+# waf installs libmpv to the wrong directory, so fix it up
+mv -f /mingw64/bin/pkgconfig/mpv.pc /mingw64/lib/pkgconfig/
+mv -f /mingw64/bin/libmpv.dll.a /mingw64/lib/
+sed -i 's_/mingw64/bin_/mingw64/lib_' /mingw64/lib/pkgconfig/mpv.pc
+rmdir /mingw64/bin/pkgconfig
+```
+
+Additional dependencies
+=======================
+
+pthreads
+--------
+
+mpv will use a pthreads wrapper by default. Either pthreads-win32 or
+winpthreads should work. The latter is packaged with most MinGW-w64
+environments, including MSYS2, so it shouldn't be a problem. If you don't have
+a pthreads wrapper or you want to build mpv without one, configure with:
+
+```bash
+./waf configure --enable-win32-internal-pthreads
+```
+
+libwaio
+-------
+
+If you want to use ``--input-file``, you need libwaio. It's available from
+git://midipix.org/waio
+
+To compile libwaio in MSYS2, run:
+
+```bash
+git clone git://midipix.org/waio && cd waio
+
+# 32-bit build, run from mingw32_shell.bat
+./build-mingw-nt32 lib-static CC=gcc AR=ar
+cp -r include/waio /mingw32/include
+cp lib32/libwaio.a /mingw32/lib
+
+# 64-bit build, run from mingw64_shell.bat
+./build-mingw-nt64 lib-static CC=gcc AR=ar
+cp -r include/waio /mingw64/include
+cp lib64/libwaio.a /mingw64/lib
+```

-# Download MXE. Note that compiling the required packages requires about 1.4 GB
-# or more!
-
-cd /opt
-git clone https://github.com/mxe/mxe mingw
-cd mingw
-
-# Set build options.
-
-# The JOBS environment variable controls threads to use when building. DO NOT
-# use the regular `make -j4` option with MXE as it will slow down the build.
-# Alternatively, you can set this in the make command by appending "JOBS=4"
-# to the end of command:
-echo "JOBS := 4" >> settings.mk
-
-# The MXE_TARGET environment variable builds MinGW-w64 for 32 bit targets.
-# Alternatively, you can specify this in the make command by appending
-# "MXE_TARGETS=i686-w64-mingw32" to the end of command:
-echo "MXE_TARGETS := i686-w64-mingw32" >> settings.mk
-
-# If you want to build 64 bit version, use this:
-# echo "MXE_TARGETS := x86_64-w64-mingw32" >> settings.mk
-
-# Build required packages. The following provide a minimum required to build
-# mpv.
-
-make gcc ffmpeg libass jpeg pthreads
-
-# Add MXE binaries to $PATH
-export PATH=/opt/mingw/usr/bin/:$PATH

+        Handling of multichannel/surround audio changed in mpv 0.8.0 from the
+        behavior in MPlayer/mplayer2 and older versions of mpv.
+
+        The old behavior is that the player always downmixed to stereo by
+        default. The ``--audio-channels`` (or ``--channels`` before that) option
+        had to be set to get multichannel audio. Then playing stereo would
+        use the ``default`` device (which typically allows multiple programs
+        to play audio at the same time via dmix), while playing anything with
+        more channels would open one of the hardware devices, e.g. via the
+        ``surround51`` alias (typically with exclusive access). Whether the
+        player would use exclusive access or not would depend on the file
+        being played.
+
+        The new behavior since mpv 0.8.0 always enables multichannel audio,
+        i.e. ``--audio-channels=auto`` is the default. However, since ALSA
+        provides no good way to play multichannel audio in a non-exclusive
+        way (without blocking other applications from using audio), the player
+        is restricted to the capabilities of the ``default`` device by default,
+        which means it supports only stereo and mono (at least with current
+        typical ALSA configurations). But if a hardware device is selected,
+        then multichannel audio will typically work.
+
+        The short story is: if you want multichannel audio with ALSA, use
+        ``--audio-device`` to select the device (use ``--audio-device=help``
+        to get a list of all devices and their mpv name).
+
+        You can also try `using the upmix plugin <http://git.io/vfuAy>`_.
+        This setup enables multichannel audio on the ``default`` device

-General Changes from MPlayer to mpv
------------------------------------
-
-This listing is about changes introduced by mplayer2 and mpv relatively to
-MPlayer.
-
-Player
-~~~~~~
-
-* New name for the binary (``mpv``). New location for config files (either
-  ``~/.config/mpv/mpv.conf``, or if you want, ``~/.mpv/config``).
-* Encoding functionality (replacement for MEncoder, see the `ENCODING`_ section).
-* Support for Lua scripting (see the `LUA SCRIPTING`_ section).
-* Better pause handling (e.g. do not unpause on a command).
-* Precise seeking support.
-* Improvements in audio/video sync handling.
-* Do not lose settings when playing a new file in the same player instance.
-* Slave mode compatibility broken (see below).
-* Re-enable screensaver while the player is paused.
-* Allow resuming playback at a later point with ``Shift+q``, also see the
-  ``quit_watch_later`` input command.
-* ``--keep-open`` option to stop the player from closing the window and
-  exiting after playback ends.
-* A client API, that allows embedding **mpv** into applications
-  (see ``libmpv/client.h`` in the sources).
-
-Input
-~~~~~
-
-* Improved default keybindings. MPlayer bindings are also available (see
-  ``etc/mplayer-input.conf`` in the source tree).
-* Improved responsiveness on user input.
-* Support for modifier keys (alt, shift, ctrl) in input.conf.
-* Allow customizing whether a key binding for seeking shows the video time, the
-  OSD bar, or nothing (see the `Input Command Prefixes`_ section).
-* Support mapping multiple commands to one key.
-
-Audio
-~~~~~
-
-* Support for gapless audio (see the ``--gapless-audio`` option).
-* Support for OSS4 volume control.
-* Improved support for PulseAudio.
-* Make ``--softvol`` default (**mpv** is not a mixer control panel).
-* By default, do pitch correction if playback speed is increased.
-* Improved downmixing and output of surround audio:
-
-  - Instead of using hardcoded pan filters to do remixing, libavresample is used
-  - Channel maps are used to identify the channel layout, so e.g. ``3.0`` and
-    ``2.1`` audio can be distinguished.
-
-Video
-~~~~~
-
-* Wayland support.
-* Native support for VAAPI and VDA. Improved VDPAU video output.
-* Improved OpenGL output (see the ``opengl-hq`` video output).
-* Make hardware decoding work with the ``opengl`` video output.
-* Support for libavfilter (for video->video and audio->audio). This allows
-  using most of FFmpeg's filters, which improve greatly on the old MPlayer
-  filters in features, performance, and correctness.
-* More correct color reproduction (color matrix generation).
-* Better subtitle rendering using libass by default.
-* Improvements when playing multiple files (``--fixed-vo`` is default, do not
-  reset settings by default when playing a new file).
-* Replace image video outputs (``--vo=jpeg`` etc.) with ``--vo=image``.
-* Removal of ``--vo=gif89a``, ``--vo=md5sum``, ``--vo=yuv4mpeg``, as encoding
-  can handle these use cases. For yuv4mpeg, for example, use::
-
-    mpv input.mkv -o output.y4m --no-audio --oautofps --oneverdrop
-
-* Image subtitles (DVDs etc.) are rendered in color and use more correct
-  positioning (color for image subs can be disabled with ``--sub-gray``).
-
-OSD and terminal
-~~~~~~~~~~~~~~~~
-
-* Cleaned up terminal output: nicer status line, less useless noise.
-* Improved OSD rendering using libass, with full Unicode support.
-* New OSD bar with chapter marks. Not positioned in the middle of the video
-  (this can be customized with the ``--osd-bar-align-y`` option).
-* Display list of chapters and audio/subtitle tracks on OSD (see the
-  `Properties`_ section).
-
-Screenshots
-~~~~~~~~~~~
-
-* Instant screenshots without 1-frame delay.
-* Support for taking screenshots even with hardware decoding.
-* Support for saving screenshots as JPEG or PNG.
-* Support for configurable file names.
-* Support for taking screenshots with or without subtitles.
-
-Note that the ``screenshot`` video filter is not needed anymore, and should not
-be put into the mpv config file.
-
-Miscellaneous
-~~~~~~~~~~~~~
-
-* Better MKV support (e.g. ordered chapters, 3D metadata).
-* Matroska edition switching at runtime.
-* Support for playing URLs of popular streaming sites directly.
-  (e.g. ``mpv https://www.youtube.com/watch?v=...``).
-  Requires a recent version of ``youtube-dl`` to be installed, and
-  ``ytdl=yes`` in the mpv config file.
-* Support for precise scrolling which scales the parameter of commands. If the
-  input doesn't support precise scrolling the scale factor stays 1.
-* Allow changing/adjusting video filters at runtime. (This is also used to make
-  the ``D`` key insert vf_yadif if deinterlacing is not supported otherwise).
-* Improved support for .cue files.
-
-Mac OS X
-~~~~~~~~
-
-* Native OpenGL backend.
-* Cocoa event loop is independent from MPlayer's event loop, so user
-  actions like accessing menus and live resizing do not block the playback.
-* Apple Remote support.
-* Media Keys support.
-* VDA support using libavcodec hwaccel API instead of FFmpeg's decoder with up
-  to 2-2.5x reduction in CPU usage.
-
-Windows
-~~~~~~~
-
-* Improved support for Unicode file names.
-* Improved window handling.
-* Do not block playback when moving the window.
-* Improved Direct3D video output.
-* Added WASAPI audio output.
-
-Internal changes
-~~~~~~~~~~~~~~~~
-
-* Switch to GPLv2+ (see ``Copyright`` file for details).
-* Removal of lots of cruft:
-
-  - Internal GUI (replaced by the OSC, see the `ON SCREEN CONTROLLER`_ section).
-  - MEncoder (replaced by native encoding, see the `ENCODING`_ section).
-  - OSD menu.
-  - Kernel video drivers for Linux 2.4 (including VIDIX).
-  - Teletext support.
-  - Support for dead platforms.
-  - Most built-in demuxers have been replaced by their libavformat counterparts.
-  - Built-in network support has been replaced by libavformat's (which also
-    supports https URLs).
-  - Embedded copies of libraries (such as FFmpeg).
-
-* General code cleanups (including refactoring or rewrites of many parts).
-* New build system.
-* Many bug fixes and removal of long-standing issues.
-* Generally preferring FFmpeg/Libav over internal demuxers, decoders, and
-  filters.
-
-Detailed Listing of User-visible Changes
-----------------------------------------
-
-This listing is about changed command line switches, slave commands, and similar
-things. Completely removed features are not listed.
-
-Command Line Switches
-~~~~~~~~~~~~~~~~~~~~~
-
-* There is a new command line syntax, which is generally preferred over the old
-  syntax. ``-optname optvalue`` becomes ``--optname=optvalue``.
-
-  The old syntax will not be removed. However, the new syntax is mentioned in
-  all documentation and so on, and unlike the old syntax is not ambiguous,
-  so it is a good thing to know about this change.
-* In general, negating switches like ``-noopt`` now have to be written as
-  ``-no-opt`` or ``--no-opt``.
-* Per-file options are not the default anymore. You can explicitly specify
-  file-local options. See ``Usage`` section.
-* Many options have been renamed, removed or changed semantics. Some options
-  that are required for a good playback experience with MPlayer are now
-  superfluous or even worse than the defaults, so make sure to read the manual
-  before trying to use your existing configuration with **mpv**.

-        Due to lack of hardware and users using the TV/DVB/PVR features, and

-        if testers are available. Otherwise, some of the TV code will be
-        removed at some point.
-
-Slave mode
-~~~~~~~~~~
-
-* Slave mode was removed. A proper slave mode application needed tons of code
-  and hacks to get
-  it right. The main problem is that slave mode is a bad and incomplete
-  interface, and to get around that, applications parsed output messages
-  intended for users. It is hard to know which messages exactly are parsed by
-  slave mode applications. This makes it virtually impossible to improve
-  terminal output intended for users without possibly breaking something.
-
-  This is absolutely insane, and since initial improvements to **mpv** quickly
-  made slave mode incompatible to most applications, it was removed as useless
-  cruft. The client API (see below) is provided instead.
-
-  ``--identify`` was replaced by the ``TOOLS/mpv_identify.sh`` wrapper script.
-
-* For some time (until including release 0.4.x), mpv supported a
-  ``--slave-broken`` option. The following options are equivalent:
-
-  ::
-
-        --input-file=/dev/stdin --input-terminal=no
-
-
-  Assuming the system supports ``/dev/stdin``.
-
-  (The option was readded in 0.5.1 and sets exactly these options.)
-
-* A JSON RPC protocol giving access to the client API is also supported. See
-  `JSON IPC`_ for more information.
-
-* **mpv** also provides a client API, which can be used to embed the player
-  by loading it as shared library. (See ``libmpv/client.h`` in the sources.)
-  It might also be possible to implement a custom slave mode-like protocol
-  using Lua scripting.
-
-Policy for Removed Features
----------------------------
-
-**mpv** is in active development. If something is in the way of more important
-development (such as fixing bugs or implementing new features), we sometimes
-remove features. Usually this happens only with old features that either seem
-to be useless, or are not used by anyone. Often these are obscure, or
-"inherited", or were marked experimental, but never received any particular
-praise by any users.
-
-Sometimes, features are replaced by something new. The new code will be either
-simpler or more powerful, but doesn't necessarily provide everything the old
-feature did.
-
-We can not exclude that we accidentally remove features that are actually
-popular. Generally, we do not know how much a specific functionality is used.
-If you miss a feature and think it should be re-added, please open an issue
-on the mpv bug tracker. Hopefully, a solution can be found. Often, it turns
-out that re-adding something is not much of a problem, or that there are
-better alternatives.
-
-Why this Fork?
---------------
-
-mplayer2 is practically dead, and mpv started out as a branch containing
-new/experimental development. (Some of it was merged right *after* the fork
-was made public, seemingly as an acknowledgment that development, or at
-least merging, should have been more active.)
-
-MPlayer is focused on not breaking anything, but is stuck with a horrible
-codebase resistant to cleanup. (Unless you do what mpv did - merciless and
-consequent pruning of bad, old code.) Cleanup and keeping broken things
-conflict, so the kind of development mpv strives for can't be done within
-MPlayer due to clashing development policies.
-
-Additionally, mplayer2 already had lots of changes over MPlayer, which would
-have needed to be backported to the MPlayer codebase. This would not only
-have been hard (several years of diverging development), but also would have
-been impossible due to the aforementioned MPlayer development policy.

+
+Hooks
+~~~~~
+
+Hooks are synchronous events between player core and a script or similar. This
+applies to the Lua scripting interface and the client API and only. Normally,
+events are supposed to be asynchronous, and the hook API provides an awkward
+and obscure way to handle events that require stricter coordination. There are
+no API stability guarantees made. Not following the protocol exactly can make
+the player freeze randomly. Basically, nobody should use this API.
+
+There are two special commands involved. Also, the client must listen for
+client messages (``MPV_EVENT_CLIENT_MESSAGE`` in the C API).
+
+``hook_add <hook-name> <id> <priority>``
+    Subscribe to the hook identified by the first argument (basically, the
+    name of event). The ``id`` argument is an arbitrary integer chosen by the
+    user. ``priority`` is used to sort all hook handlers globally across all
+    clients. Each client can register multiple hook handlers (even for the
+    same hook-name). Once the hook is registered, it cannot be unregistered.
+
+    When a specific event happens, all registered handlers are run serially.
+    This uses a protocol every client has to follow explicitly. When a hook
+    handler is run, a client message (``MPV_EVENT_CLIENT_MESSAGE``) is sent to
+    the client which registered the hook. This message has the following
+    arguments:
+
+    1. the string ``hook_run``
+    2. the ``id`` argument the hook was registered with as string (this can be
+       used to correctly handle multiple hooks registered by the same client,
+       as long as the ``id`` argument is unique in the client)
+    3. something undefined, used by the hook mechanism to track hook execution
+       (currently, it's the hook-name, but this might change without warning)
+
+    Upon receiving this message, the client can handle the event. While doing
+    this, the player core will still react to requests, but playback will
+    typically be stopped.
+
+    When the client is done, it must continue the core's hook execution by
+    running the ``hook_ack`` command.
+
+``hook_ack <string>``
+    Run the next hook in the global chain of hooks. The argument is the 3rd
+    argument of the client message that starts hook execution for the
+    current client.
+
+The following hooks are currently defined:
+
+``on_load``
+    Called when a file is to be opened, before anything is actually done.
+    For example, you could read and write the ``stream-open-filename``
+    property to redirect an URL to something else (consider support for
+    streaming sites which rarely give the user a direct media URL), or
+    you could set per-file options with by setting the property
+    ``file-local-options/<option name>``. The player will wait until all
+    hooks are run.
+
+``on_unload``
+    Run before closing a file, and before actually uninitializing
+    everything. It's not possible to resume playback in this state.

+Escaping spaces and other special characters
+--------------------------------------------
 
-    The suboption parser (used for example for ``--ao=pcm`` suboptions)
-    supports a special kind of string-escaping intended for use with external
-    GUIs.
+Keep in mind that the shell will partially parse and mangle the arguments you
+pass to mpv. For example, you might need to quote or escape options and
+filenames:
 
-It has the following format::
+    ``mpv "filename with spaces.mkv" --title="window title"``
+
+It gets more complicated if the suboption parser is involved. The suboption
+parser puts several options into a single string, and passes them to a
+component at once, instead of using multiple options on the level of the
+command line.
+
+The suboption parser can quote strings with ``"``, ``'``, and ``[...]``.
+Additionally, there is a special form of quoting with ``%n%`` described below.
+
+For example, the ``opengl`` VO can take multiple options:
+
+    ``mpv test.mkv --vo=opengl:scale=lanczos:icc-profile=file.icc,xv``
+
+This passes ``scale=lanczos`` and ``icc-profile=file.icc`` to ``opengl``,
+and also specifies ``xv`` as fallback VO. If the icc-profile path contains
+spaces or characters like ``,`` or ``:``, you need to quote them:
+
+    ``mpv '--vo=opengl:icc-profile="file with spaces.icc",xv'``
+
+Shells may actually strip some quotes from the string passed to the commandline,
+so the example quotes the string twice, ensuring that mpv recieves the ``"``
+quotes.
+
+The ``[...]`` form of quotes wraps everything between ``[`` and ``]``. It's
+useful with shells that don't interpret these characters in the middle of
+an argument (like bash). These quotes are balanced (since mpv 0.9.0): the ``[``
+and ``]`` nest, and the quote terminates on the last ``]`` that has no matching
+``[`` within the string. (For example, ``[a[b]c]`` results in ``a[b]c``.)
+
+The fixed-length quoting syntax is intended for use with external
+scripts and programs.
+
+It is started with ``%`` and has the following format::
 
     %n%string_of_length_n
 
@@ -253,6 +297,15 @@ It has the following format::
 
     ``mpv --ao=pcm:file=%`expr length "$NAME"`%"$NAME" test.avi``
 
+Suboptions passed to the client API are also subject to escaping. Using
+``mpv_set_option_string()`` is exactly like passing ``--name=data`` to the
+command line (but without shell processing of the string). Some options
+support passing values in a more structured way instead of flat strings, and
+can avoid the suboption parsing mess. For example, ``--vf`` supports
+``MPV_FORMAT_NODE``, which let's you pass suboptions as a nested data structure
+of maps and arrays. (``--vo`` supports this in the same way, although this

+PSEUDO GUI MODE
+===============
+
+mpv has no official GUI, other than the OSC (`ON SCREEN CONTROLLER`_), which
+is not a full GUI and is not meant to be. However, to compensate for the lack
+of expected GUI behavior, mpv will in some cases start with some settings
+changed to behave slightly more like a GUI mode.
+
+Currently this happens only in the following cases:
+
+- if started using the ``mpv.desktop`` file on Linux (e.g. started from menus
+  or file associations provided by desktop environments)
+- if started from explorer.exe on Windows (technically, if it was started on
+  Windows, and all of the stdout/stderr/stdin handles are unset)
+- manually adding ``--profile=pseudo-gui`` to the command line
+
+This mode implicitly adds ``--profile=pseudo-gui`` to the command line, with
+the ``pseudo-gui`` profile being predefined with the following contents:
+
+::
+
+    [pseudo-gui]
+    terminal=no
+    force-window=yes
+    idle=once
+
+This follows the mpv config file format. To customize pseudo-GUI mode, you can
+put your own ``pseudo-gui`` profile into your ``mpv.conf``. This profile will
+enhance the default profile, rather than overwrite it.
+
+The profile always overrides other settings in ``mpv.conf``.

-``divtc[=options]``
-    Inverse telecine for deinterlaced video. If 3:2-pulldown telecined video
-    has lost one of the fields or is deinterlaced using a method that keeps
-    one field and interpolates the other, the result is a juddering video that
-    has every fourth frame duplicated. This filter is intended to find and
-    drop those duplicates and restore the original film framerate. Two
-    different modes are available: One-pass mode is the default and is
-    straightforward to use, but has the disadvantage that any changes in the
-    telecine phase (lost frames or bad edits) cause momentary judder until the
-    filter can resync again. Two-pass mode avoids this by analyzing the entire
-    video beforehand so it will have forward knowledge about the phase changes
-    and can resync at the exact spot. These passes do *not* correspond to pass
-    one and two of the encoding process. You must run an extra pass using
-    ``divtc`` pass one before the actual encoding throwing the resulting video
-    away. Then use ``divtc`` pass two for the actual encoding. If you use
-    multiple encoder passes, use ``divtc`` pass two for all of them.
-
-    The options are:
-
-    ``pass=1|2``
-        Use two pass mode.
-
-    ``file=<filename>``
-        Set the two pass log filename (default: ``framediff.log``).
-
-    ``threshold=<value>``
-        Set the minimum strength the telecine pattern must have for the filter
-        to believe in it (default: 0.5). This is used to avoid recognizing
-        false pattern from the parts of the video that are very dark or very
-        still.
-
-    ``window=<numframes>``
-        Set the number of past frames to look at when searching for pattern
-        (default: 30). Longer window improves the reliability of the pattern
-        search, but shorter window improves the reaction time to the changes
-        in the telecine phase. This only affects the one-pass mode. The
-        two-pass mode currently uses fixed window that extends to both future
-        and past.
-
-    ``phase=0|1|2|3|4``
-        Sets the initial telecine phase for one pass mode (default: 0). The
-        two-pass mode can see the future, so it is able to use the correct
-        phase from the beginning, but one-pass mode can only guess. It catches
-        the correct phase when it finds it, but this option can be used to fix
-        the possible juddering at the beginning. The first pass of the two
-        pass mode also uses this, so if you save the output from the first
-        pass, you get constant phase result.
-
-    ``deghost=<value>``
-        Set the deghosting threshold (0-255 for one-pass mode, -255-255 for
-        two-pass mode, default 0). If nonzero, deghosting mode is used. This
-        is for video that has been deinterlaced by blending the fields
-        together instead of dropping one of the fields. Deghosting amplifies
-        any compression artifacts in the blended frames, so the parameter
-        value is used as a threshold to exclude those pixels from deghosting
-        that differ from the previous frame less than specified value. If two
-        pass mode is used, then negative value can be used to make the filter
-        analyze the whole video in the beginning of pass-2 to determine
-        whether it needs deghosting or not and then select either zero or the
-        absolute value of the parameter. Specify this option for pass 2, it
-        makes no difference on pass 1.
-
-``phase[=t|b|p|a|u|T|B|A|U][:v]``
-    Delay interlaced video by one field time so that the field order changes.
-    The intended use is to fix PAL videos that have been captured with the
-    opposite field order to the film-to-video transfer. The options are:
-
-    ``t``
-        Capture field order top-first, transfer bottom-first. Filter will
-        delay the bottom field.
-
-    ``b``
-        Capture bottom-first, transfer top-first. Filter will delay the top
-        field.
-
-    ``p``
-        Capture and transfer with the same field order. This mode only exists
-        for the documentation of the other options to refer to, but if you
-        actually select it, the filter will faithfully do nothing ;-)
-
-    ``a``
-        Capture field order determined automatically by field flags, transfer
-        opposite. Filter selects among ``t`` and ``b`` modes on a frame by frame
-        basis using field flags. If no field information is available, then this
-        works just like ``u``.
-
-    ``u``
-        Capture unknown or varying, transfer opposite. Filter selects among
-        ``t`` and ``b`` on a frame by frame basis by analyzing the images and
-        selecting the alternative that produces best match between the fields.
-
-    ``T``
-        Capture top-first, transfer unknown or varying. Filter selects among
-        ``t`` and ``p`` using image analysis.

+            exchange for adding some blur. This filter is good at temporal
+            interpolation, and also known as "smoothmotion" (see ``tscale``).

+        If set to 0, the kernel's preferred blur factor is used. Note that
+        setting this too low (eg. 0.5) leads to bad results. It's generally

+
+    ``scale-radius=<value>``

-    ``approx-gamma``
-        Approximate the actual gamma function as a pure power curve of
-        1.95. A number of video editing programs and studios apparently use this
-        for mastering instead of the true curve. Most notably, anything in the
-        Apple ecosystem uses this approximation - including all programs
-        compatible with it. It's a sound idea to try enabling this flag first
-        when watching videos and shows to see if things look better that way.

     ``3dlut-size=<r>x<g>x<b>``
         Size of the 3D LUT generated from the ICC profile in each dimension.
         Default is 128x256x64.
         Sizes must be a power of two, and 512 at most.
 
+    ``blend-subtitles=<yes|video|no>``
+        Blend subtitles directly onto upscaled video frames, before
+        interpolation and/or color management (default: no). Enabling this
+        causes subtitles to be affected by ``icc-profile``, ``target-prim``,
+        ``target-trc``, ``interpolation``, ``gamma`` and ``linear-scaling``.
+        It also increases subtitle performance when using ``interpolation``.
+
+        The downside of enabling this is that it restricts subtitles to the
+        visible portion of the video, so you can't have subtitles exist in the
+        black margins below a video (for example).
+
+        If ``video`` is selected, the behavior is similar to ``yes``, but subs
+        are drawn at the video's native resolution, and scaled along with the
+        video.
+
+        .. warning:: This changes the way subtitle colors are handled. Normally,
+                     subtitle colors are assumed to be in sRGB and color managed
+                     as such. Enabling this makes them treated as being in the
+                     video's color space instead. This is good if you want
+                     things like softsubbed ASS signs to match the video colors,
+                     but may cause SRT subtitles or similar to look slightly off.

-``opengl-old``
-    OpenGL video output driver, old version. Video size must be smaller
-    than the maximum texture size of your OpenGL implementation. Intended to
-    work even with the most basic OpenGL implementations, but also makes use
-    of newer extensions which allow support for more color spaces.
-
-    The code performs very few checks, so if a feature does not work, this
-    might be because it is not supported by your card and/or OpenGL
-    implementation, even if you do not get any error message. Use ``glxinfo``
-    or a similar tool to display the supported OpenGL extensions.
-
-    .. note:: This driver is for compatibility with old systems.
-
-    ``(no-)ati-hack``
-        ATI drivers may give a corrupted image when PBOs are used (when using
-        ``force-pbo``). This option fixes this, at the expense of using a bit
-        more memory.
-    ``(no-)force-pbo``
-        Always uses PBOs to transfer textures even if this involves an extra
-        copy. Currently this gives a little extra speed with NVIDIA drivers
-        and a lot more speed with ATI drivers. May need the ``ati-hack``
-        suboption to work correctly.

-
-    ``swapinterval=<n>``
-        Minimum interval between two buffer swaps, counted in displayed frames
-        (default: 1). 1 is equivalent to enabling VSYNC, 0 to disabling VSYNC.
-        Values below 0 will leave it at the system default. This limits the
-        framerate to (horizontal refresh rate / n). Requires

-        implementations this only works in fullscreen mode.
-    ``ycbcr``
-        Use the ``GL_MESA_ycbcr_texture`` extension to convert YUV to RGB. In

+CHANGES FROM OTHER VERSIONS OF MPLAYER
+======================================
+
+**mpv** is based on mplayer2, which in turn is based on the original MPlayer
+(also called mplayer, mplayer-svn, mplayer1). Many changes have been made, a
+large part of which is incompatible or completely changes how the player
+behaves. Although there are still many similarities to its ancestors, **mpv**
+should generally be treated as a completely different program.
+
+.. note::
+    These lists are incomplete.
+
+General Changes from MPlayer to mpv
+-----------------------------------
+
+This listing is about changes introduced by mplayer2 and mpv relatively to
+MPlayer.
+
+Player
+~~~~~~
+
+* New name for the binary (``mpv``). New location for config files (either
+  ``~/.config/mpv/mpv.conf``, or if you want, ``~/.mpv/config``).
+* Encoding functionality (replacement for MEncoder, see the `ENCODING`_ section).
+* Support for Lua scripting (see the `LUA SCRIPTING`_ section).
+* Better pause handling (e.g. do not unpause on a command).
+* Precise seeking support.
+* Improvements in audio/video sync handling.
+* Do not lose settings when playing a new file in the same player instance.
+* Slave mode compatibility broken (see below).
+* Re-enable screensaver while the player is paused.
+* Allow resuming playback at a later point with ``Shift+q``, also see the
+  ``quit_watch_later`` input command.
+* ``--keep-open`` option to stop the player from closing the window and
+  exiting after playback ends.
+* A client API, that allows embedding **mpv** into applications
+  (see ``libmpv/client.h`` in the sources).
+
+Input
+~~~~~
+
+* Improved default keybindings. MPlayer bindings are also available (see
+  ``etc/mplayer-input.conf`` in the source tree).
+* Improved responsiveness on user input.
+* Support for modifier keys (alt, shift, ctrl) in input.conf.
+* Allow customizing whether a key binding for seeking shows the video time, the
+  OSD bar, or nothing (see the `Input Command Prefixes`_ section).
+* Support mapping multiple commands to one key.
+* Classic LIRC support was removed. Install remotes as input devices instead.
+  This way they will send X11 key events to the mpv window, which can be bound
+  using the normal ``input.conf``.
+* Joystick support was removed. It was considered useless and was the cause
+  of some problems (e.g. a laptop's accelerator being recognized as joystick).
+
+Audio
+~~~~~
+
+* Support for gapless audio (see the ``--gapless-audio`` option).
+* Support for OSS4 volume control.
+* Improved support for PulseAudio.
+* Make ``--softvol`` default (**mpv** is not a mixer control panel).
+* By default, do pitch correction if playback speed is increased.
+* Improved downmixing and output of surround audio:
+
+  - Instead of using hardcoded pan filters to do remixing, libavresample is used
+  - Channel maps are used to identify the channel layout, so e.g. ``3.0`` and
+    ``2.1`` audio can be distinguished.
+
+Video
+~~~~~
+
+* Wayland support.
+* Native support for VAAPI and VDA. Improved VDPAU video output.
+* Improved OpenGL output (see the ``opengl-hq`` video output).
+* Make hardware decoding work with the ``opengl`` video output.
+* Support for libavfilter (for video->video and audio->audio). This allows
+  using most of FFmpeg's filters, which improve greatly on the old MPlayer
+  filters in features, performance, and correctness.
+* More correct color reproduction (color matrix generation), including support
+  for BT.2020 (Ultra HD) and linear XYZ (Digital Cinema) inputs.
+* Support for color managed displays, via ICC profiles.
+* High-quality image resamplers (see the ``opengl`` ``scale`` suboption).
+* Support for scaling in (sigmoidized) linear light.
+* Better subtitle rendering using libass by default.
+* Improvements when playing multiple files (``-fixed-vo`` is default, do not
+  reset settings by default when playing a new file).
+* Replace image video outputs (``--vo=jpeg`` etc.) with ``--vo=image``.
+* Removal of ``--vo=gif89a``, ``--vo=md5sum``, ``--vo=yuv4mpeg``, as encoding
+  can handle these use cases. For yuv4mpeg, for example, use::
+
+    mpv input.mkv -o output.y4m --no-audio --oautofps --oneverdrop
+
+* Image subtitles (DVDs etc.) are rendered in color and use more correct
+  positioning (color for image subs can be disabled with ``--sub-gray``).
+
+OSD and terminal
+~~~~~~~~~~~~~~~~
+
+* Cleaned up terminal output: nicer status line, less useless noise.
+* Improved OSD rendering using libass, with full Unicode support.
+* New OSD bar with chapter marks. Not positioned in the middle of the video
+  (this can be customized with the ``--osd-bar-align-y`` option).
+* Display list of chapters and audio/subtitle tracks on OSD (see the
+  `Properties`_ section).
+
+Screenshots
+~~~~~~~~~~~
+
+* Instant screenshots without 1-frame delay.
+* Support for taking screenshots even with hardware decoding.
+* Support for saving screenshots as JPEG or PNG.
+* Support for configurable file names.
+* Support for taking screenshots with or without subtitles.
+
+Note that the ``screenshot`` video filter is not needed anymore, and should not
+be put into the mpv config file.
+
+Miscellaneous
+~~~~~~~~~~~~~
+
+* Better MKV support (e.g. ordered chapters, 3D metadata).
+* Matroska edition switching at runtime.
+* Support for playing URLs of popular streaming sites directly.
+  (e.g. ``mpv https://www.youtube.com/watch?v=...``).
+  Requires a recent version of ``youtube-dl`` to be installed. Can be
+  disabled with ``ytdl=no`` in the mpv config file.
+* Support for precise scrolling which scales the parameter of commands. If the
+  input doesn't support precise scrolling the scale factor stays 1.
+* Allow changing/adjusting video filters at runtime. (This is also used to make
+  the ``D`` key insert vf_yadif if deinterlacing is not supported otherwise).
+* Improved support for .cue files.
+
+Mac OS X
+~~~~~~~~
+
+* Native OpenGL backend.
+* Cocoa event loop is independent from MPlayer's event loop, so user
+  actions like accessing menus and live resizing do not block the playback.
+* Apple Remote support.
+* Media Keys support.
+* VDA support using libavcodec hwaccel API instead of FFmpeg's decoder with up
+  to 2-2.5x reduction in CPU usage.
+
+Windows
+~~~~~~~
+
+* Improved support for Unicode file names.
+* Improved window handling.
+* Do not block playback when moving the window.
+* Improved Direct3D video output.
+* Added WASAPI audio output.
+
+Internal changes
+~~~~~~~~~~~~~~~~
+
+* Switch to GPLv2+ (see ``Copyright`` file for details).
+* Removal of lots of cruft:
+
+  - Internal GUI (replaced by the OSC, see the `ON SCREEN CONTROLLER`_ section).
+  - MEncoder (replaced by native encoding, see the `ENCODING`_ section).
+  - OSD menu.
+  - Kernel video drivers for Linux 2.4 (including VIDIX).
+  - Teletext support.
+  - Support for dead platforms.
+  - Most built-in demuxers have been replaced by their libavformat counterparts.
+  - Built-in network support has been replaced by libavformat's (which also
+    supports https URLs).
+  - Embedded copies of libraries (such as FFmpeg).
+
+* General code cleanups (including refactoring or rewrites of many parts).
+* New build system.
+* Many bug fixes and removal of long-standing issues.
+* Generally preferring FFmpeg/Libav over internal demuxers, decoders, and
+  filters.
+
+Detailed Listing of User-visible Changes

+things. Completely removed features are not listed.
+
+Command Line Switches
+~~~~~~~~~~~~~~~~~~~~~
+
+* There is a new command line syntax, which is generally preferred over the old
+  syntax. ``-optname optvalue`` becomes ``--optname=optvalue``.
+
+  The old syntax will not be removed. However, the new syntax is mentioned in
+  all documentation and so on, and unlike the old syntax is not ambiguous,
+  so it is a good thing to know about this change.
+* In general, negating switches like ``-noopt`` now have to be written as
+  ``-no-opt`` or ``--no-opt``.
+* Per-file options are not the default anymore. You can explicitly specify
+  file-local options. See ``Usage`` section.
+* Many options have been renamed, removed or changed semantics. Some options
+  that are required for a good playback experience with MPlayer are now
+  superfluous or even worse than the defaults, so make sure to read the manual
+  before trying to use your existing configuration with **mpv**.

+input.conf and Slave Commands

+
+* Table of renamed input commands:
+
+    This lists only commands that are not always gracefully handled by the
+    internal legacy translation layer. If an input.conf contains any legacy
+    commands, a warning will be printed when starting the player. The warnings
+    also show the replacement commands.
+
+    Properties containing ``_`` to separate words use ``-`` instead.

+
+    .. note::
+
+        Due to lack of hardware and users using the TV/DVB/PVR features, and
+        due to the need to cleanup the related command code, it's possible
+        that the new commands are buggy or behave worse. This can be improved
+        if testers are available. Otherwise, some of the TV code will be
+        removed at some point.
+
+Slave mode
+~~~~~~~~~~
+
+* Slave mode was removed. A proper slave mode application needed tons of code
+  and hacks to get
+  it right. The main problem is that slave mode is a bad and incomplete
+  interface, and to get around that, applications parsed output messages
+  intended for users. It is hard to know which messages exactly are parsed by
+  slave mode applications. This makes it virtually impossible to improve
+  terminal output intended for users without possibly breaking something.
+
+  This is absolutely insane, and since initial improvements to **mpv** quickly
+  made slave mode incompatible to most applications, it was removed as useless
+  cruft. The client API (see below) is provided instead.
+
+  ``--identify`` was replaced by the ``TOOLS/mpv_identify.sh`` wrapper script.
+
+* For some time (until including release 0.4.x), mpv supported a
+  ``--slave-broken`` option. The following options are equivalent:
+
+  ::
+
+        --input-file=/dev/stdin --input-terminal=no
+
+
+  Assuming the system supports ``/dev/stdin``.
+
+  (The option was readded in 0.5.1 and sets exactly these options.)
+
+* A JSON RPC protocol giving access to the client API is also supported. See
+  `JSON IPC`_ for more information.
+
+* **mpv** also provides a client API, which can be used to embed the player
+  by loading it as shared library. (See ``libmpv/client.h`` in the sources.)
+  It might also be possible to implement a custom slave mode-like protocol
+  using Lua scripting.
+
+Policy for Removed Features
+---------------------------
+
+**mpv** is in active development. If something is in the way of more important
+development (such as fixing bugs or implementing new features), we sometimes
+remove features. Usually this happens only with old features that either seem
+to be useless, or are not used by anyone. Often these are obscure, or
+"inherited", or were marked experimental, but never received any particular
+praise by any users.
+
+Sometimes, features are replaced by something new. The new code will be either
+simpler or more powerful, but doesn't necessarily provide everything the old
+feature did.
+
+We can not exclude that we accidentally remove features that are actually
+popular. Generally, we do not know how much a specific functionality is used.
+If you miss a feature and think it should be re-added, please open an issue
+on the mpv bug tracker. Hopefully, a solution can be found. Often, it turns
+out that re-adding something is not much of a problem, or that there are
+better alternatives.
+
+Why this Fork?
+--------------
+
+mplayer2 is practically dead, and mpv started out as a branch containing
+new/experimental development. (Some of it was merged right *after* the fork
+was made public, seemingly as an acknowledgment that development, or at
+least merging, should have been more active.)
+
+MPlayer is focused on not breaking anything, but is stuck with a horrible
+codebase resistant to cleanup. (Unless you do what mpv did - merciless and
+consequent pruning of bad, old code.) Cleanup and keeping broken things
+conflict, so the kind of development mpv strives for can't be done within
+MPlayer due to clashing development policies.
+
+Additionally, mplayer2 already had lots of changes over MPlayer, which would
+have needed to be backported to the MPlayer codebase. This would not only
+have been hard (several years of diverging development), but also would have
+been impossible due to the aforementioned MPlayer development policy.

+## Relation to MPlayer and mplayer2
+
+
+mpv is based on mplayer2, which in turn is based on the original MPlayer
+(also called mplayer, mplayer-svn, mplayer1). Many changes have been made, a
+large part of which is incompatible or completely changes how the player
+behaves. Although there are still many similarities to its ancestors, mpv
+should generally be treated as a completely different program.
+
+mpv was forked because we wanted to modernize MPlayer. This includes
+removing cruft (including features which stopped making sense 10 years ago),
+and of course adding modern features. Such huge and intrusive changes made it
+infeasible to work directly with MPlayer, which is mostly focused on
+preservation, so a fork had to be made. (Actually, mpv is based on mplayer2,
+which already started this process of removing cruft.)
+
+In general, mpv should be considered a completely new program, rather than a
+MPlayer drop-in replacement.
+
+If you are wondering what's different from mplayer2 and MPlayer, an incomplete
+list of changes is located [here][mplayer-changes].

+Release 0.9.0
+=============
+
+Changes
+-------
+
+Changes that may break users' config files have been annotated with a `(!)`.
+
+- Note: mpv is not compatible with Lua 5.3. Lua 5.1 or 5.2 is required.
+- The minimum required libass version is now 0.12.1 or newer.
+- The minimum required FFmpeg version is now 2.4.0 (equiv. Libav 11) or newer.
+- The internal libmpg123 support was removed. This was already not used by
+  default in the previous release.
+- `(!)` The LIRC support was removed. Configure LIRC remotes as input devices
+  instead.
+- `(!)` The Linux Joystick support was removed.
+- `(!)` `vf_screenshot` was removed, as they are now handled at a VO level and
+  is compatible with all VOs.
+- `(!)` `--ass-use-margins` has been renamed to `--sub-use-margins` and applies
+  only to plain-text (non-ASS) subtitles (enabled by default). The new
+  `--ass-force-margins` option applies only to ASS subtitles (disabled by
+  default). To get the old behaviour back, enable both at the same time.
+- `(!)` The `--sub-scale-with-window` option now only applies to plain text
+  (non-ASS) subtitles (enabled by default). The new `--ass-scale-with-window`
+  option does the same but only with ASS subtitles (disabled by default).
+- `(!)` The range for the `param1` for the `gaussian` `vo_opengl` scaler has
+  been redefined. Instead of being an arbitrary 1-100 range, have a default
+  value of 1.0, and anything higher is blurrier.
+- `(!)` The `seek`, `playlist_next, `playlist_prev`, `loadfile` and `loadlist`
+  parameters no longer accept numerical parameters where symbolic parameter
+  names exist.
+- `(!)` `vo_opengl` changes:
+  - `(!)` The `smoothmotion` suboption has been renamed to `interpolation`.
+    The old name is still supported for now.
+  - `(!)` The `bilinear_slow` scaler has been renamed to `triangle`.
+  - `(!)` `scale-down` has been renamed to `dscale` and now has its own set of
+    config options (e.g. `dscale-radius`).
+  - `(!)` Scaler radius no longer defaults to `3` but to a preferred value
+    that may be different for each filter.
+  - The `scale-radius` option may now go down as low as `0.5`, which is the
+    value used by the `nearest` filter.
+  - `spline36` is the new `cscale` default for `opengl-hq`. This might break
+    setups that use `fbo-format=rgb8`. To work around it, leave `fbo-format`
+    as its default, or set to something higher than 8, or set `cscale=bilinear`,
+    the previous default.
+- `(!)` `vf_format` no longer converts video to YUYV if there is no parameter.
+  Video is now passed unchanged unless a format is specifically requested.
+- `(!)` The `--colormatrix`, `--colormatrix-input-range`,
+  `--colormatrix-output-range` and `--colormatrix-primaries` options have been
+  converted into `vf_format` suboptions. See commit 27715b7 and the manual for
+  details.
+- `vf_mirror`'s implementation was replaced with calling into `libavfilter`'s
+  `vf_hflip` filter, thus depending on `libavfilter` to function.
+- The `device` subption to `ao_wasapi` has been deprecated in favor of
+  `--audio-device`.
+- `--video-rotate` now allows 360 as an argument instead of stopping at 359.
+- Several improvements to `af_scaletempo`.
+- Options that have multiple options and also include a "yes" option now
+  default to that if specified with no arguments.
+- The default value of `--cache-default` is now 150000 (153.6 MB, ~146 MiB).
+- JPEG screenshots now use the same subsampling as the source video. The images
+  are still RGB regardless of source format though.
+
+Bug fixes
+---------
+
+- mpv no longer saves position on files that can't be resumed (issue #1701).
+- (X11) Fix the player thinking the mouse has left the window in some WMs /
+  embeddings (issue #1672).
+- mpv no longer freezes on wayland when the compositor stops asking it to draw
+  itself (e.g. when minimized) (issue #249).
+- `.ac3` files are no longer rejected by `--audio-file-auto` (issue #1759).
+- `ao_wasapi` now automatically enables `exclusive` when passthrough is
+  attempted (issue #1742).
+- Attempt to fix flickering on Intel VAAPI drivers with `--hwdec=vaapi` and
+  `--vo=opengl` (issue #1765).
+- `youtube-dl` will no longer download video streams when video playback
+  is disabled with `--no-video`.
+- (Windows) mpv now prevents system sleep when playing a video-only file.
+  Previously, only files with an opened audio track would prevent sleep.
+
+New features
+------------
+
+- `vo_opengl` features:
+  - Added `ewa_ginseng`, `ewa_hanning`, `robidoux`, `robidouxsharp`,
+    `oversample` and `haasnsoft` scalers.
+  - There are now `ewa_lanczossoft` and `ewa_lanczossharp` aliases to
+    `ewa_lanczos` that are tuned to be blurrier and sharper, respectively.
+  - Added `gamma-auto` option that uses ambient light sensors to automatically
+    adjust the video gamma. See commit c028d78 for details.
+  - Added `blend-subtitles` option to draw subtitles directly into the video
+    instead of rendered afterwards. Potentially necessary for correct rendering
+    with files that use ASS subtitles for typesetting in combination with an
+    `icc-profile`. There is a default option for drawing after upscaling,
+    and a `video` option for drawing before upscaling. See details and warning
+    on the manual.
+  - There is now a `tscale` option, used to choose the temporal scaler used
+    in the `interpolation` mode (previously `smoothmotion`).
+  - There is a new `scale-blur` parameter to adjust the amount of blur that
+    most of the filters produce. Deviating from the default may introduce
+    artifacts in EWA filters.
+  - (Windows) There is now a `dwmflush` option that might help improve
+    rendering of high-fps video. Disabled by default. See manual for options.
+- New Linux-only `vo_drm` video output driver. Uses the direct rendering /
+  kernel modesetting drivers to draw directly to the framebuffer, but with
+  no hardware acceleration. See manual for details.
+- New `pseudo-gui` builtin profile, automatically used when launched from
+  `mpv.desktop` by opening `mpv.exe` on windows (`mpv.com` still works as
+  usual), or by opening the `mpv.app` bundle. The `pseudo-gui` tries to make
+  the player window behave closer to what a desktop player would do, by not
+  immediately closing and allowing the user to drag&drop files for playback.
+  See manual for details.
+- mpv can now play directories by automatically playing their contents instead.
+  Works everywhere but on Windows, due to issues with Windows' C runtime.
+- Add support to pitch correct stretched audio with librubberband.
+- Add support for the Raspberry Pi 2's hardware decoder when FFmpeg (or Libav)
+  is built with `--enable-mmal`. See commit 8fff125 for details.
+- The `--cache` option now accepts a "yes" option, that always enables a
+  `--cache-default`-sized cache on all cases a cache can be used, unless
+  `--cache-default` disables caching.
+- `ao_pulse`, `ao_coreaudio` and `ao_wasapi` now support device hotplugging.
+- New `--osd-align-x` and `--osd-align-y` options can be used to align the OSD
+  independently from subtitles.
+- New `--osd-bold` and `--sub-text-bold` options can be enabled to bold all
+  OSD or plain-text subtitle text, respectively.
+- Added a default keybind to the `u` key that enables/disables ASS style
+  overriding. When enabled, is equivalent to `--ass-style-override=force`.
+- There is now a `MOUSE_ENTER` keybind, that is called when the mouse cursor
+  enters the VO from outside.
+- The new `--ytdl-params` option can be set to arguments that are always given
+  to `youtube-dl` invocations. There is no sanity checking, so invalid options
+  can prevent `mpv` from working with http URLs.
+- There's a new `--demuxer-mkv-fix-timestamps` option, enabled by default, that
+  tries to guess more accurate video timestamps by using FPS information, if
+  available. See manual for details.
+- The new `--window-scale` option can be used to scale the video window by the
+  specified multiplier, before other options such as `--autofit` are applied.
+- `vo_direct3d_shaders` now supports NV12 colorspace without using stretchrect,
+  but it seems no drivers actually support that.
+- (Client API) Added a `rescan_external_files` command, as requested on issue
+  #1586.
+- (Client API) If enabled, initializing the Client API will now also load the
+  user's `mpv.conf`.
+- (Client API) There's a new `mpv_opengl_cb_report_flip()` call for API users
+  to call to inform mpv of when exactly a frame was displayed.
+- (Client API) The `mpv_opengl_cb_render()` function was deprecated in favor
+  of the new, simpler `mpv_opengl_cb_draw()` function.
+- (Client API) There is a new `screenshot_raw` command. See `input.rst` for
+  details.
+- The `--input-file` argument may now also be a file descriptor in the form
+  "fd://N", where N is the FD number.
+

+- (X11) Fix crash on `vo_xv:no-colorkey` with the Overlay adapter. (bug #1629)
+- (X11) `--stop-screensaver` is now implemented by calling into
+  `xdg-screensaver`, fixing some compatibility issues that prevented it from
+  actually stopping screensavers.
+- Make the video equalizer work correctly on some VAAPI drivers. (bug #1647)
+- Prevent OSD from disappearing when clicking on mozplugger. (bug #1672)
+- The new DVB-S2 support code, using S2API, now builds on FreeBSD.
+- Fix decoding of seekable matroska from unseekable network stream. (bug #1656)
+- (OSX) Fix crashing when closing a VO's window (usually at exit). (bug #1657)

+- (OSX) Fix mouse cursor autohiding when the player is fullscreen.
+- `vf_vavpp` (VAAPI postprocessing) now deinterlaces video correctly.
+- `smb://` streams now use the stream cache (used to be inefficient).
+- (Windows) Do not hide the mouse cursor when it is hovering the window menu.
+- Fix 8-channel output on `ao_jack`. (bug #1688)
+- Fix `--mf-fps` parameter on JPEG files. (bug #1689)
+- Fix anamorphic scaling being ignored if it was very minor.

+
+Release 0.8.0
+=============
+
+Changes
+-------
+
+Changes that may break users' config files have been annotated with a `(!)`.
+
+- `(!)` vo_opengl_old has been removed. OpenGL rendering now requires hardware
+  that can do at least OpenGL 2.1, the oldest version supported by vo_opengl.
+- `(!)` vf_pp has been removed. A version of it can still be accessed through
+  lavfilter (e.g. --vf=lavfi=[pp...]), but it receives no QP information.
+  Also, vf_dlopen no longer passes QP information to its loaded plugin either
+  (it's always 0).
+- `(!)` vf_softpulldown, vf_swapuv, vf_phase, vf_divtc and vf_ilpack have all
+  been removed. Ports or alternative versions of these filters are available
+  through libavfilter (vf_lavfi).
+- vf_pullup and vf_noise now are simply wrappers to their libavfilter
+  equivalents. Both are only currently available on FFmpeg (not Libav).
+- `(!)` ao_portaudio has been removed. There is good support for the native
+  audio drivers of all major desktop platforms, as well as ao_sdl and
+  ao_openal as fallbacks.
+- `(!)` vo_opengl's `lscale` suboption has been renamed to `scale`; `lradius`
+  is now `scale-radius`, `lparam1` and `lparam2` are now respectively
+  `scale-param1` and `scale-param2`; `lscale-down` is now `scale-down`.
+  The `cscale` suboption remains as is.
+- `(!)` Several of the `vo_opengl` radius-preset aliases supported by `scale`
+  have been removed; use `scale-radius` to set if needed. For example, use
+  `--vo=opengl:scale=lanczos:scale-radius=2` instead of `scale=lanczos2`.
+  The default radius is recommended for most filters.
+- `(!)` vo_opengl no longer supports the `stereo` suboption. The anaglyph
+  effect can be reproduced with the stereo3d filter. The quadbuffer support,
+  which requires expensive specialized hardware to begin with, is removed.
+- `(!)` The `approx-gamma` suboption to vo_opengl has been removed. The
+  BT.1886 specification says that it's actually how it's supposed to be done
+  so it is now the default when `srgb` or `icc-profile` are enabled. This does
+  not include BT.1886's gamma drop.
+- `(!)` The `no-scale-sep` and `indirect` suboptions to vo_opengl have been
+  removed. These are now autodetected and enabled whenever they would have
+  benefit.
+- `(!)` The `--lua` and `--lua-opts` parameters / options are now called
+  `--script` and `--script-opts`, respectively. The `lua` subdir of the mpv
+  config dir is also now expected to be called `scripts` instead.
+- `(!)` The `--fixed-vo` option has been removed. It has been the default for
+  a long time anyway, and disabling fixed-vo is not useful.
+- vo_opengl_hq has been updated to take into account new features.
+  `fancy-downscaling` and `sigmoid-upscaling` are enabled,
+  "mitchell" is now the default for `scale-down`.
+- The `sub-visibility` OSD message is now clearer about whether subtitles
+  are hidden or just not available / selected.
+- The device IDs given to `--audio-device` for use with ao_coreaudio now use
+  UIDs, so they don't change when devices are added/removed or after reboots.
+- `--msg-level` now also accepts ',' as separator.
+- (Client API) The client API now refuses to initialize if the LC_NUMERIC
+  locale is not "C".
+- (Client API) The native type of the `msg-level` parameter is now a key-value
+  list. Setting or reading it as a string still works.
+- (Slave API) The `get_property` command is now deprecated.
+- Documentation updates.
+- PDF documentation is now disabled by default due to rst2pdf being fickle,
+  causing weird build errors.
+- Print desync messages with negative A/V sync as well. While rare, it could
+  happen with some uses of `--autosync`.
+
+Bug fixes
+---------
+
+- (Windows) Avoid resizing the video window when player is minimized, might
+  address bug #1547.
+- (NetBSD) Fix build with v4l2.
+- (Linux) Attempt to address conflicts with the pulseaudio mixer. (bug #1578)
+- Multiple cdda:// fixes. (bugs #1555, #1560)
+- VP9 timestamps no longer cause "missing PTS" warnings with new enough FFmpeg
+  builds.
+- Fix a crash when using H.264 hardware decoding on new enough libavcodecs.
+  (bug #1587)
+
+New features
+------------
+
+- vo_opengl now supports frame blending to eliminate stuttering when the video
+  framerate does not nicely match the display framerate through the
+  `smoothmotion` suboption. This is not meant to artificially increase the
+  video's FPS, so there is no "soap opera effect" or difficulties with some
+  video types (e.g. anime).
+- vo_opengl now supports sigmoidal upscaling (e.g. for fullscreen), which
+  reduces ringing induced by upscaling, enabled through the
+  `sigmoid-upscaling` suboption.
+- vo_opengl now supports ewa_lanczos (Jinc) scaling, which provides higher
+  quality with less aliasing. It supports an experimental `scale-antiringing`
+  parameter, which tries to further reduce video ringing.
+- vo_opengl now has a `linear-scaling` suboption, that makes the scalers work
+  in linear light. Implied by the `srgb`, `icc-profile` or the new
+  `sigmoid-upscaling` suboption.
+- vo_opengl has improved downscaling for higher downscale ratios when
+  `fancy-downscaling` is enabled.
+- Add `--keep-open=always` to make `--keep-open` apply to all files instead of
+  only the last.
+- mpv now filters the tags that are printed on the console to try to hide
+  useless metadata. The filter works as a whitelist, and can be configured
+  with the `--display-tags` option.
+- Add a `--sub-scale-by-window` option that, when set to 'no', prevents
+  subtitles from changing their pixel size when the window changes sizes.
+- vo_opengl now technically has GLES 2 and 3 support (but not GLES 1). GLES 3
+  support is only tested on Mesa's software emulation. GLES 2 has been tested
+  on nvidia drivers. Both GLES modes are feature deficient and inefficient due
+  to GLES limitations, so they should not be preferred over the standard
+  OpenGL mode.
+- (X11) vo_opengl now supports the `icc-profile-auto` option on X11 hosts.
+- The 'A' key now by default cycles through a list of preset aspect ratios.
+  Meant to be used to work around broken files.
+- There is now a "force" mode for `--loop`. Works like "inf", but tries to
+  open files/streams even if there was an error on the previous attempt.
+- There is now a `--log-file` option to write mpv's log messages to a specifed
+  file.
+- There is now a `--audio-file-auto` option to automatically load an external
+  audio file with certain constraints. Will only load external audio if the
+  playing file has a video stream. Set to "exact" by default. (bug #967)
+- There is now a `--network-timeout` option to specify a timeout in seconds
+  for network access. If 0 (default), uses the libavformat default. If a
+  protocol that doesn't support timeouts is used, this option is ignored.
+- (X11) The XF86 special keys are now all mappable in `input.conf`. All keys
+  documented in `XF86keysym.h` are available, but only as their numeric codes.
+- (Linux) The DVB implementation now supports DVB-S2 through S2API.
+- (Linux) The VDR format for `channels.conf` is now supported and preferred.
+  See http://linuxtv.org/vdrwiki/index.php/Syntax_of_channels.conf for the
+  syntax. Tuning to DVB-S2 channels requires the VDR-format `channels.conf`.
+- (Linux) There is now a `--dvbin-full-transponder` option for handling
+  special broadcast cases where PIDs switch, or just to work around incomplete
+  PID data.
+- (Client API) There is now an opengl_cb VO, which receives the OpenGL context
+  from the libmpv client. This allows a client to render libmpv video directly
+  to a provided OpenGL context without having to use --wid embedding.
+- (Client API) The aforementioned --wid parameter can now be set at any time,
+  but has no effect if a file is already loaded.
+- (Client API) The list of DVD titles can now be queried.
+- (Client API) There is now a `filtered-metadata` property, containing only
+  the tags allowed by `--display-tags`.
+- (Client API) There is now support for XEmbed `--wid` targets, such as a
+  `GtkSocket`'s `gtk_socket_get_id()`.
+- (Client API) There is now a `file-format` property with a symbolic name
+  for the file format. In some cases this might be a comma separated list
+  of various different extensions due to libavformat idiosyncrasies.
+- (Client API) There is now a `mouse` command for generating mouse events
+  over the video window.
+- (Client API) There is now a `partially-seekable` property that indicates
+  whether a file is only considered `seekable` because of the stream cache,
+  but would not be seekable otherwise (e.g. realtime stream, or HTTP with
+  no resume support). Small relative seeks may be fine, but larger seeks
+  will likely fail.
+- (Client API) There is now an MPV_EVENT_QUEUE_OVERFLOW event that is posted
+  whenever events have to be dropped because the queue is full. No further
+  events are posted until the MPV_EVENT_QUEUE_OVERFLOW is consumed to avoid
+  duplicated posting.
+- (Client API) There is now a helper `mpv_wait_async_requests()` function
+  that blocks until all known async requests have completed. (bug #1542)
+- (Client API) There is now a `detected-hwdec` property that returns the
+  detected hardware decoder when one is successfully opened. This probably
+  only returns a valid value after playback has started.
+- (Client API) There are now `audio_add`, `audio_remove` and `audio_reload`
+  counterparts to the equivalent `sub_` commands for handling external audio
+  files.
+
+This listing is not complete. A complete changelog can be seen by running
+`git log v0.7.0..v0.8.0` in the git repository.
+
+Release 0.7.3
+=============
+
+Changes
+-------
+
+- Several documentation updates and typo fixes.
+- Don't show "0%" position when the stream is infinite / has unknown length.
+- Fixes the config file loading order so that lower priority `mpv.conf` files
+  don't override higher priority `config` files.
+- (OSX) Remove coreaudio_exclusive from the "auto" codec list.
+- Failing to create a GL3 context is now a warning instead of error, to reduce
+  user confusion.
+- The subtitle decoder now gets reset when cycling subtitles. This makes the
+  currently shown subtitle event disappear even if cycling back to the current
+  subtitle track.
+- `--shuffle` and `--merge-files` now affects the contents of playlist files,
+  instead of just the list of files given as arguments to mpv.
+- `./waf install` avoids installing a few additional data/config files if only
+  libmpv was built.
+- Improved channel mapping when the file's channel map doesn't match the AO's
+  available channel maps.
+- (OSX) VDA now gracefully refuses to run on non-OpenGL3-capable systems instead
+  of trying and failing to build its shaders.
+- Add workaround for vf_vapoursynth filters that expect an FPS.
+- The default value for `--screenshot-template` now shows up in
+  `--list-options`.
+- `ao_pulse`'s `latency-hacks` suboption is now off by default, as it causes
+  issues with newer pulseaudio releases. If A/V Sync issues happen, either
+  add the `latency-hacks=on` pulse suboption in mpv.conf, or update the
+  pulseaudio daemon (bug #1430).
+- (Linux) `ao_alsa` now deals better with audio device disconnection.
+- Client API: timestamp properties that have no value return "no" instead of
+  magic number.
+
+Bug fixes
+---------
+
+- (Windows, OSX) Many `ao_wasapi` and `ao_coreaudio` fixes.
+- (OSX) Make the window title update correctly on OS X Yosemite.
+- Fixes for handling mono audio on various AOs.
+- (Linux) Fixes resuming from suspend on ao_alsa.
+- Fixes for playlist file parsing.
+- Overly long options in the --list-options output now break the column layout
+  instead of getting truncated; fixes shell completion scripts.
+- Fix rendering resolution of certain DVB subtitles (bug #1425).
+- Fix EDL or --merge-files breaking timestamps with .avi files.
+- Workaround for libavcodec bug with the VP9 codec parser (bug #1448),
+  fixes possible crash.
+- Improve robustness of the matroska parser with broken files (bugs #1457,
+  #1461).
+- Improve 10bit video compatibility with older GPUs (specially Intel) (bug
+  #1383).
+- Fixes flashing the VO window when playing a list of files that includes
+  non-media files (bug #1459).
+- Workaround for window embedding in OpenBox (bug #1235)
+- Fixes for several crashes and lockups (bugs #838, #1389, #1408, #1463, #1473,
+  #1474).
+- Fixes for the zsh completion script (bugs #997)
+
+New features
+------------
+
+- mpv now prints the contents of its config.h when running in verbose mode, to
+  aid with debugging.
+- The `include=` option now accepts `~` to refer to the HOME dir (bug #1406).
+- `af_volume` now prints ReplayGain values in verbose mode.
+- m3u playlists that don't have the `#EXTM3U` header are now accepted if they
+  "look like" ASCII or UTF-8 text and have the .m3u extension.
+- Chapter marks in the seek bar now update when switching files.
+- Supports embedded cover art in MKV files (bug #1374).
+- (Windows) Video window can now be resized even with --no-border.
+- (Windows) Client API: the "run" command now works on Windows too.
+- (Linux) vo_wayland now supports key modifiers (Meta, Alt, Control, Shift)
+- Client API: "display-names" property is now observable.
+
+This listing is not complete. A complete changelog can be seen by running
+`git log v0.7.2..v0.7.3` in the git repository.
+
+Release 0.7.2
+=============
+
+Changes
+-------
+
+- Give precedence to the DVD menu navigation keyboard bindings so that user
+  defined LEFT/RIGHT/... bindings don't break DVD menu navigation.
+- Try to fallback to the "default" device if the selected device is busy in the
+  alsa AO.
+- Don't create Dock icon for audio only files on OS X.
+- Save screenshots to desktop when using the app bundle on OS X.
+- Restore ab-loop settings with playback resume.
+- Bump required youtube-dl version to 2014.11.26 and enable the ytdl_hook Lua
+  script by default (now playing videos from YouTube and the like will work
+  out of the box without any configuration change needed).
+
+Bug fixes
+---------
+
+- Don't signal an error if --stream-dump is used.
+- Fix removing key bindings from Lua scripts.
+- Reject channel descriptions with too many channels in the coreaudio AO.
+- Don't async redraw when waiting for VO redraw on OS X (this fixes the very
+  annoying glitch where the black bars disappear for a single frame when going
+  fullscreen).
+- Fix mono playback with the also AO.
+- Don't crash if framebuffers are not available in the opengl VO.
+
+New features
+------------
+
+- Try to handle multi-arc videos in the ytdl_hook Lua script.
+
+This listing is not complete. There are many more bug fixes and changes. The
+complete change log can be viewed by running ``git log 47ec404..c7d6b21`` in
+the git repository.
+
+Release 0.7.1
+=============
+
+Changes
+-------
+
+- Don't show the volume neutral marker on the OSD if softvol is disabled.
+- Don't select a subtitle track when executing the sub_add input command in
+  "auto" mode.
+
+Bug fixes
+---------
+
+- Fix busy loop when seeking while paused (this fixes a problem with pulseaudio
+  that caused mpv and the pulseaudio daemon to use 100% CPU).
+- Fix Lua function utils.subprocess() in Windows versions older than Vista.
+- Avoid creating a window bigger than the screen on Windows.
+- Don't ignore the last line in m3u playlists.
+- Don't crash if a codec could not be opened.
+- Dynamically allocate audio channel map entries (this should fix a crash in
+  the alsa and coreaudio AOs with audio devices that support more than 20
+  channel maps).
+- Ignore the "srgb" option in the opengl VO if hardware decoding is enabled.
+- Linearize non-RGB sRGB files correctly (eg. JPEG).
+- Fix opening reference URLs (.file/id=) on OS X.
+
+This listing is not complete. There are many more bug fixes and changes. The
+complete change log can be viewed by running ``git log 8d8b36d..6583ad6`` in
+the git repository.
+
+Release 0.7.0
+=============
+
+Changes
+-------
+
+- Buffer partial log messages in the client API (the client API will now only
+  pass full log messages to clients).
+- Remove ncurses/terminfo/termcap support (it was disabled by default and
+  replaced by new code since v0.6.0).
+- Enable cdda:// support by default again (it was disabled since v0.6.0).
+- Cascade-load input.conf (if there are several input.confs in the set of valid
+  config paths, load them all).
+- Draw the OSD twice in 3D mode (this fixes subtitles display in 3D mode).
+- Make wasapi the default AO on Windows again since many of its problems have
+  been solved.
+- Use "site-functions" subdir to install the zsh completion script instead of
+  the Debian-specific "vendor-completions" (also provide the --zshdir waf
+  configure option for changing this value).
+- Improve synchronization between the Cocoa GUI and the player (this fixes some
+  long standing deadlock issues on Mac OS X).
+- Remove --fs-missioncontrol option (only relevant to Mac OS X).
+
+New features
+------------
+
+- Enable pitch correction by default when playing at higher speeds (this can be
+  controlled with the --audio-pitch-correction option).
+- Open stream and demuxer asynchronously (this should avoid having the player
+  get blocked on network streams).
+- Add cache-buffering-state property for querying the cache fill status until
+  the player unpauses.
+- Add support for listing and selecting the audio device (note that it is not
+  implemented for all AOs, see the --audio-device option for more information).
+- Add support for a JSON-based IPC mechanism (note that this is not currently
+  supported on Windows, see the JSON IPC section in the manpage for more
+  information).
+- Add Lua utility function for starting processes (see utils.subprocess() in the
+  manpage).
+- Add Lua utility function for parsing JSON (see utils.parse_json() in the
+  manpage).
+- Add field-dominance property (see --field-dominance option).
+- Add video-rotate property (see --video-rotate option).
+- Add playback-abort property for querying whether playback is stopped or is to
+  be stopped.
+- Add cursor-autohide property (see --cursor-autohide option).
+- Add vo-configured property for querying whether a window is created.
+- Add support for dxva2 hardware acceleration on Windows.
+- Drop libquvi support (this has been replaced by a built-in Lua script that
+  invokes the youtube-dl tool, which needs to be installed, see the --ytdl
+  option).
+- Add support for loading chapters from an external file (see the
+  --chapters-file option).
+- Add window-minimized property for querying whether the window is minimized
+  (works for X11 only).
+- Make it possible to configure the OSC seekbar style (see the "seekbarstyle"
+  OSC option).
+- Add support for libmpv on Mac OS X (it used to be broken, now it's fully
+  functional and also provides support for embedding the mpv window inside a
+  Cocoa/Qt application).
+- Try to use the audio channel map reported by ALSA in the alsa AO.
+- Add option to disable text OSD rendering completely (useful for working around
+  certain fontconfig issues, see the --use-text-osd option).
+
+This listing is not complete. There are many more bug fixes and changes. The
+complete change log can be viewed by running ``git log 7759c18..9479daa`` in
+the git repository.
