 ::
 
- --- 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
-        - add MPV_END_FILE_REASON_ERROR and the mpv_event_end_file.error field
-          for slightly better error reporting on playback failure
-        - add --stop-playback-on-init-failure option, and make it the default
-          behavior for libmpv only
-        - add qthelper.hpp set_option_variant()
-        - mark the following events as deprecated:
-            MPV_EVENT_TRACKS_CHANGED
-            MPV_EVENT_TRACK_SWITCHED
-            MPV_EVENT_PAUSE
-            MPV_EVENT_UNPAUSE
-            MPV_EVENT_METADATA_UPDATE
-            MPV_EVENT_CHAPTER_CHANGE
-          They are handled better with mpv_observe_property() as mentioned in
-          the documentation comments. They are not removed and still work.
- 1.8    - add qthelper.hpp
- 1.7    - add mpv_command_node(), mpv_command_node_async()
- 1.6    - modify "core-idle" property behavior
-        - MPV_EVENT_LOG_MESSAGE now always sends complete lines
-        - introduce numeric log levels (mpv_log_level)
- --- mpv 0.6.0 is released ---
- 1.5    - change in X11 and "--wid" behavior again. The previous change didn't
-          work as expected, and now the behavior can be explicitly controlled
-          with the "input-x11-keyboard" option. This is only a temporary
-          measure until XEmbed is implemented and confirmed working.
-          Note: in 1.6, "input-x11-keyboard" was renamed to "input-vo-keyboard",
-          although the old option name still works.
+ --- mpv 0.5.2 is released ---
  1.4    - subtle change in X11 and "--wid" behavior
-          (this change was added to 0.5.2, and broke some things, see #1090)
  --- mpv 0.5.0 is released ---
  1.3    - add MPV_MAKE_VERSION()
  1.2    - remove "stream-time-pos" property (no replacement)

+General Changes for 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.
+* Switch to GPLv2+. (Technically speaking, MPlayer as a whole seems to be
+  GPLv2-only, while mplayer2 is GPLv3+ - see ``Copyright`` file for details.)
+* Removal of the internal GUI, MEncoder, OSD menu, video kernel drivers for
+  Linux 2.4 (including VIDIX)
+* Large internal cleanups
+* Removal of support for dead platforms
+* New build system
+* No embedded copy of FFmpeg and other libraries
+* Better pause handling (do not unpause on a command)
+* Better MKV support (such as ordered chapters)
+* vo_vdpau improvements
+* Precise seeking support
+* Native OpenGL backend for OS X
+* General OS X improvements
+* Improvements in audio/video sync handling
+* Cleaned up terminal output
+* Gapless audio support (``--gapless-audio``)
+* Improved responsiveness on user input
+* Support for modifier keys (alt, shift, ctrl) in input.conf
+* OSS4 volume control
+* More correct color reproduction (color matrix generation)
+* Use libass for subtitle rendering by default (better quality)
+* Generally preferring FFmpeg/Libav over internal demuxers and decoders
+* Improvements when playing multiple files (``--fixed-vo``)
+* Screenshot improvements (instant screenshots without 1-frame delay, allow
+  taking screenshots even with hardware decoding)
+* Improved support for PulseAudio
+* Generally improved MS Windows support (dealing with Unicode file names,
+  improved ``--vo=direct3d``, improved window handling)
+* Better OSD rendering (using libass). This has full Unicode support, and
+  languages like Arabic should be better supported.
+* Cleaned up terminal output (nicer status line, less useless noise)
+* Support for playing URLs of popular streaming sites directly
+  (e.g. ``mpv https://www.youtube.com/watch?v=...``)
+* Improved OpenGL output (``--vo=opengl-hq``)
+* Make ``--softvol`` default (**mpv** is not a mixer control panel)
+* Improved support for .cue files
+* Screenshot improvements (can save screenshots as JPEG or PNG, configurable
+  file names, support for taking screenshots with or without subtitles - the
+  ``screenshot`` video filter is not needed anymore, and should not be put
+  into the mpv config file)
+* Removal of teletext support
+* Removal of most built-in demuxers, using libavformat instead
+* Removal of built-in network support, using libavformat instead (also,
+  support https via libavformat)
+* Replace image VOs (``--vo=jpeg`` etc.) with ``--vo=image``
+* Do not lose settings when playing a new file in the same player instance
+* New location for config files, new name for the binary.
+* Slave mode compatibility broken (see below)
+* Encoding functionality (replacement for MEncoder, see ``DOCS/encoding.rst``)
+* Remove ``--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 can be disabled with ``--sub-gray``)
+* Wayland support
+* Support for precise scrolling which scales the parameter of commands. If the
+  input doesn't support precise scrolling the scale factor stays 1.
+* OS X: Cocoa event loop is independent from MPlayer's event loop, so user
+  actions like accessing menus and live resizing do not block the playback.
+* OS X: Apple Remote support.
+* OS X: Media Keys support.
+* Windows: Added WASAPI audio output.
+* New OSD bar with chapter marks and not positioned in the middle of the video
+  (though this can be customized with the ``--osd-bar-align-y`` option).
+* Allow customizing whether a key binding for seeking shows the video time, the
+  OSD bar, or nothing (see section `Input Command Prefixes`_).
+* Display list of chapters and audio/subtitle tracks on OSD (see section
+  `Properties`_).
 * ``--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.
+* Re-enable screensaver while the player is paused.
+* Matroska edition switching at runtime.
 * 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.
+* Improved downmixing and output of surround audio. Instead of using hardcoded
+  pan filters to do remixing, use libavresample. Channel maps are used to
+  identify the channel layout, so e.g. ``3.0`` and ``2.1`` audio can be
+  distinguished.
+* Allow resuming playback at a later point with ``Shift+q``, also see
+  ``quit_watch_later`` input command.
+* Support mapping multiple commands to one key.
 * 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
+  the ``D`` key insert vf_yadif if deinterlacing is not supported otherwise.)
+* Native VAAPI support
+* OS X: VDA support using libavcodec hwaccel API instead of FFmpeg's decoder. 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).

-
-* 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.
+* Make hardware decoding in general work with the ``opengl`` video output.
+* Lua scripting (see `LUA SCRIPTING`_)
+* A client API, that allows embedding **mpv** into applications
+  (see ``libmpv/client.h`` in the sources)
+* General bug fixes and removal of long-standing issues
+* General code cleanups (including refactoring or rewrites of many parts)

-JSON IPC
-========
-
-mpv can be controlled by external programs using the JSON-based IPC protocol. It
-can be enabled by specifying the path to a unix socket using the option
-``--input-unix-socket``. Clients can connect to this socket and send commands to
-the player or receive events from it. You can use the ``socat`` tool to send
-commands (and receive reply) from the shell.
-
-.. warning::
-
-    This is not intended to be a secure network protocol. It is explicitly
-    insecure: there is no authentication, no encryption, and the commands
-    themselves are insecure too. For example, the ``run`` command is exposed,
-    which can run arbitrary system commands. The use-case is controlling the
-    player locally. This is not different from the MPlayer slave protocol.
-
-Protocol
---------
-
-Clients can execute commands on the player by sending JSON messages of the
-following form:
-
-::
-
-    { "command": ["command_name", "param1", "param2", ...] }
-
-where ``command_name`` is the name of the command to be executed, followed by a
-list of parameters. Parameters must be formatted as native JSON values
-(integers, strings, booleans, ...). Every message **must** be terminated with
-``\n``. Additionally, ``\n`` must not appear anywhere inside the message. In
-practice this means that messages should be minified before being sent to mpv.
-
-mpv will then send back a reply indicating whether the command was run
-correctly, and an additional field holding the command-specific return data (it
-can also be null).
-
-::
-
-    { "error": "success", "data": null }
-
-mpv will also send events to clients with JSON messages of the following form:
-
-::
-
-    { "event": "event_name" }
-
-where ``event_name`` is the name of the event. Additional event-specific fields
-can also be present. See `List of events`_ for a list of all supported events.
-
-If the first character (after skipping whitespace) is not ``{``, the command
-will be interpreted as non-JSON text command, as they are used in input.conf
-(or ``mpv_command_string()`` in the client API). Additionally, line starting
-with ``#`` and empty lines are ignored.
-
-Currently, embedded 0 bytes terminate the current line, but you should not
-rely on this.
-
-Commands
---------
-
-Additionally to  the commands described in `List of Input Commands`_, a few
-extra commands can also be used as part of the protocol:
-
-``client_name``
-    Return the name of the client as string. This is the string ``ipc-N`` with
-    N being an integer number.
-
-``get_time_us``
-    Return the current mpv internal time in microseconds as a number. This is
-    basically the system time, with an arbitrary offset.
-
-``get_property``
-    Return the value of the given property. The value will be sent in the data
-    field of the replay message.
-
-    Example:
-
-    ::
-
-        { "command": ["get_property", "volume"] }
-        { "data": 50.0, "error": "success" }
-
-``get_property_string``
-    Like ``get_property``, but the resulting data will always be a string.
-
-    Example:
-
-    ::
-
-        { "command": ["get_property_string", "volume"] }
-        { "data": "50.000000", "error": "success" }
-
-``set_property``
-    Set the given property to the given value. See `Properties`_ for more
-    information about properties.
-
-    Example:
-
-    ::
-
-        { "command": ["set_property", "pause", true] }
-        { "error": "success" }
-
-``set_property_string``
-    Like ``set_property``, but the argument value must be passed as string.
-
-    Example:
-
-    ::
-
-        { "command": ["set_property_string", "pause", "yes"] }
-        { "error": "success" }
-
-``observe_property``
-    Watch a property for changes. If the given property is changed, then an
-    event of type ``property-change`` will be generated
-
-    Example:
-
-    ::
-
-        { "command": ["observe_property", 1, "volume"] }
-        { "error": "success" }
-        { "event": "property-change", "id": 1, "data": 52.0, "name": "volume" }
-
-``observe_property_string``
-    Like ``observe_property``, but the resulting data will always be a string.
-
-    Example:
-
-    ::
-
-        { "command": ["observe_property_string", 1, "volume"] }
-        { "error": "success" }
-        { "event": "property-change", "id": 1, "data": "52.000000", "name": "volume" }
-
-``unobserve_property``
-    Undo ``observe_property`` or ``observe_property_string``. This requires the
-    numeric id passed to the observe command as argument.
-
-    Example:
-
-    ::
-
-        { "command": ["unobserve_property", 1] }
-        { "error": "success" }
-
-``request_log_messages``
-    Enable output of mpv log messages. They will be received as events. The
-    parameter to this command is the log-level (see ``mpv_request_log_messages``
-    C API function).
-
-    Log message output is meant for humans only (mostly for debugging).
-    Attempting to retrieve information by parsing these messages will just
-    lead to breakages with future mpv releases. Instead, make a feature request,
-    and ask for a proper event that returns the information you need.
-
-``suspend``
-    Suspend the mpv main loop. There is a long-winded explanation of this in
-    the C API function ``mpv_suspend()``. In short, this prevents the player
-    from displaying the next video frame, so that you don't get blocked when
-    trying to access the player.
-
-``resume``
-    Undo one ``suspend`` call. ``suspend`` increments an internal counter, and
-    ``resume`` decrements it. When 0 is reached, the player is actually resumed.
-
-``get_version``
-    Returns the client API version the C API of the remote mpv instance
-    provides. (Also see ``DOCS/client-api-changes.rst``.)
-
-UTF-8
------
-
-Normally, all strings are in UTF-8. Sometimes it can happen that strings are
-in some broken encoding (often happens with file tags and such, and filenames
-on many Unixes are not required to be in UTF-8 either). This means that mpv
-sometimes sends invalid JSON. If that is a problem for the client application's
-parser, it should filter the raw data for invalid UTF-8 sequences and perform
-the desired replacement, before feeding the data to its JSON parser.
-
-mpv will not attempt to construct invalid UTF-8 with broken escape sequences.

-    kind.)
-
-    The returned value uses similar conventions as ``mp.get_property_native()``
-    to distinguish empty objects and arrays.
-
-    If the ``trail`` parameter is ``true`` (or any value equal to ``true``),

-TERMINAL STATUS LINE
-====================
-
-During playback, mpv shows the playback status on the terminal. It looks like
-something like this:
-
-    ``AV: 00:03:12 / 00:24:25 (13%) A-V: -0.000``
-
-The status line can be overridden with the ``--term-status-msg`` option.
-
-The following is a list of things that can show up in the status line. Input
-properties, that can be used to get the same information manually, are also
-listed.
-
-- ``AV:`` or ``V:`` (video only) or ``A:`` (audio only)
-- The current time position in ``HH:MM:SS`` format (``playback-time`` property)
-- The total file duration (or ``00:00:00`` if unknown) (``length`` property)
-- Playback speed, e.g. `` x2.0``. Only visible if the speed is not normal. This
-  is the user-requested speed, and not the actual speed  (usually they should
-  be the same, unless playback is too slow). (``speed`` property.)
-- Playback percentage, e.g. ``(13%)``. How much of the file has been played.
-  Normally calculated out of playback position and duration, but can fallback
-  to other methods (like byte position) if these are not available.
-  (``percent-pos`` property.)
-- The audio/video sync as ``A-V:  0.000``. This is the difference between
-  audio and video time. Normally it should be 0 or close to 0. If it's growing,
-  it might indicate a playback problem. (``avsync`` property.)
-- Total A/V sync change, e.g. ``ct: -0.417``. Normally invisible. Can show up
-  if there is audio "missing", or not enough frames can be dropped. Usually
-  this will indicate a problem. (``total-avsync-change`` property.)
-- Encoding state in ``{...}``, only shown in encoding mode.
-- Dropped frames, e.g. ``Dropped: 4``. Shows up only if the count is not 0. Can
-  grow if the video framerate is higher than that of the display, or if video
-  rendering is too slow. Also can be incremented on "hiccups" and when the video
-  frame couldn't be displayed on time. (``vo-drop-frame-count`` property.)
-  If the decoder drops frames, the number of decoder-dropped frames is appended
-  to the display as well, e.g.: ``Dropped: 4/34``. This should almost never
-  happen, unless decoder-framedropping is enabled with one of the
-  ``--framedrop`` options, the stream contains errors, or a weird codec is in
-  use. (``drop-frame-count`` property.)
-- Cache state, e.g. ``Cache:  2s+134KB``. Visible if the stream cache is enabled.
-  The first value shows the amount of video buffered in the demuxer in seconds,
-  the second value shows *additional* data buffered in the stream cache in
-  kilobytes. (``demuxer-cache-duration`` and ``cached-used`` properties.)

-Release 0.7.0
+Release 0.5.2
 =============
 
 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).
+- Inherit event flags from parent X11 window when using --wid.
+- Properly resume playlists loaded at runtime (this makes mpv try to resume a
+  playlist when loaded like "mpv playlist.m3u").
+- Don't honor $XDG_CONFIG_DIRS anymore for global paths (this fixes a regression
+  on systems that set the variable by default to somewhere else then /etc,
+  making mpv skip previously created config files).
+- Allow up to 256 MB of extradata to make broken files work.
+
+Bug fixes
+---------
+
+- Restore old speed change behavior (this fixes a temporary lack of sound after
+  restoring normal speed e.g. when pressing Backspace).
+- Fix quit handling when seeking past EOF while paused.
+- Prevent burning CPU when seeking while paused.
+- Don't add the playlist base path twice when using --playlist.
+- Fix a crash when the initialization of the EGL context fails on Wayland.
+- Make EOF handling properly event-based (this fixes a bug that made mpv hang
+  when changing from one file to the next with --gapless-audio=no).
+- Assume icy title data is terminated with ';' (this fixes handling of streams
+  with metadata containing apostrophes).

+
+Release 0.5.1
+=============
+
+Changes
+-------
+
+- Add audio/flac to the MIME type list in mpv.desktop.
+- The --slave-broken option has been reintroduced and is equivalent to using
+  --input-file=/dev/stdin and --input-terminal=no.
+
+Bug fixes
+---------
+
+- Fix screenshots with anamorphic videos in the vdpau vo.
+- Fix a crash happening when mpv fails to create a vdpau mixer in the vdpau vo.
+- Don't quit when the --loop-file option is used.
+- Always load the cursor theme in the wayland vo (this fixes a crash caused by
+  moving the mouse cursor over the video).
+- Properly return non-zero from the zsh completion script when no matches are
+  found (this fixes the use of user-defined zsh completion matchers).
+- Fix the description of the opengl-hq vo default options in the manpage.
+- Remove duplicated content from the manpage that was accidentally added in the
+  manpage reorganization from the previous release.
+- Avoid clobbering playback position on video end (when both audio and video
+  streams reached the end, the playback poisition was briefly set at 0).
+- Avoid overwriting user input in the coreaudio_device ao.

+
+Release 0.5.0
+=============
+
+Changes
+-------
+
+- Support setting the start time relative to the start PTS with --start.
+- Use /dev/sr0 as default cdrom/dvd device on Linux.
+- Change "cache" property representation to float.
+- Split the ao_coreaudio audio output into ao_coreaudio (which uses the
+  AudioUnits and the CoreAudio sound server) and ao_coreaudio_device (which uses
+  direct device access).
+- Complete supported URL schemes in the zsh completion script.
+- Enable compiler optimizations (-O2) during build.
+- Allow precise seeking with percent-based seeks too.
+- Do precise seeks when clicking on the OSC seekbar.
+- Remove support for older VDA hwaccel versions on Mac OS X (requires recent
+  versions of ffmpeg/libav).
+- Remove the last remains of slave mode (--slave-broken option). Support for
+  reading input commands from stdin can be emulated using: --input-terminal=no
+  --input-file=/dev/stdin.
+- Some key binding were remapped or removed:
+  + "LEFT" and "RIGHT" have been remapped to seek 5 seconds instead of 10.
+  + "c" for changing the YUV color space was unmapped.
+  + OSD level cycling has been remapped from "o" to "O".
+  + "o" is now mapped to the show_progress command (like "P").
+  + "PGUP" and "PGDWN" have been remapped to chapter-based seeks (the old
+    bindings "@" and "!" are still available). The old behvaiour has been
+    remapped to "Shift+PGUP" and "Shift+PGDWM".
+  + Increasing/decreasing audio delay have been remapped from "+" and "-" to
+    "Ctrl++" and "Ctrl+-".
+  + "(" and ")" for adjusting audio balance have been unmapped.
+  + "F" for toggling the "sub-forced-only" option has been unmapped.
+  + "TAB" for cycling TS programs has been unmapped.
+  + "A" for cycling DVD angle has been unmapped.
+  + "U" for stopping playback has been unmapped.
+  + "l" and "L" for cycling quvi format have been unmapped.
+- Make it possible to build the client API (libmpv) on Mac OS X.
+- Do necessary checks for nested Wayland compositors which only have limited
+  interfaces.
+- The options in the manpage have been re-organized into sections and ordered by
+  usage to make it easier to navigate.
+- The "hard" framedrop mode has been removed (this behaviour is still available
+  via the --vd-lavc-framedrop option).
+- Show the basename of a subtitle file only (without the directory part).
+
+Bug fixes
+---------
+
+- Use a default color space for files with no video (this fixes color managed
+  OSD messages when no video channel is present).
+- Fix key equivalent dispatching for Cocoa on Mac OS X.
+- Disable non-interleaved audio formats by default with ao_alsa, since some
+  ALSA plugins don't cope well with them (non-interleaved formats can still be
+  enabled using the "non-interleaved" ao_alsa option).
+- Fix deadlock in the client API when calling mpv_terminate_destroy() before
+  mpv_initialize().
+- Fix flushing of filter chain (this fixes a bug where the last frames would get
+  dropped on EOF, if buffered by filters).
+- Actually use the channels.conf configuration file for DVB.
+- Restore the --dvbin-file option.
+- Fix off by one error in the command parser which caused a segfault when using
+  the mp.commandv() Lua function with 10 or more arguments.
 
 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).
+- Search for config files in $XDG_CONFIG_HOME and $XDG_CONFIG_DIRS in addition
+  to ~/.mpv. The config file has also been renamed to mpv.conf (although the
+  old file still works and will be loaded even if the new one exists).
+- Add "playback-time" property that returns the current playback time always
+  starting at 0. This is now used to show the playback time in the OSD and the
+  status line, fixing the shown playback time for transport streams that start
+  at a completely random timestamp.
+- Add cache-related "cache-free", "cache-used" and "cache-idle" properties.
+- Add option to list supported protocols (--list-protocols).
+- Allow setting libavformat stream options with the --stream-lavf-o option.
+- Support running the demuxer in a separate thread and prefetch packets (this
+  can be enabled using the --demuxer-thread option).

--- This script uses the lavfi idet filter to automatically insert the
--- appropriate deinterlacing filter based on a short section of the
--- currently playing video.
---
--- It registers the key-binding ctrl+d, which when pressed, inserts
--- the filter vf=lavfi=idet. After 4 second, it examines the results
--- to determine whether the content progressive or interlaced and the
--- interlacing field dominance. It immediately sets the latter within
--- mpv.
---
--- If the content is judged not to be progressive, it may be either
--- interlaced or telecined. To determine which one, the video is
--- seeked back to the detection starting point with the "pullup"
--- filter inserted. After another four seconds, if idet thinks that
--- the pulled up viedo is "progressive", then pullup is the correct
--- filter and this script leaves it in places while removing the idet
--- filter. Otherwise, the content plain interlaced and mpv's deinterlace
--- property is set. This will usually insert the yadif deinterlacing filter.
---
--- The default detection time may be overridden by adding
---
--- --lua-opts=autodeint.detect_seconds=<number of seconds>
---
--- to mpv's arguments. This may be desirable to allow idet more
--- time to collect data.
---
--- To see counts of the various types of frames for each detection phase,
