Release 0.4.0

Key bindings are decided on the "down" event, so if the prefix is not
unique, the first/shortest will be used (e.g. when both "a" and "a-b"
are mapped, "a" will always be chosen).

This also breaks combining multiple mouse buttons. But it seems users
expect it to work, and it's indeed a bit strange that it shouldn't work,
as mouse bindings are emitted on the key "up" event, not "down" (if the
shorter binding didn't emit a command yet, why shouldn't it be
combinable).

Deal with this by clearing the key history when a command is actually
emitted, instead of when a command is decided. This means if both
MOUSE_BTN0 and MOUSE_BTN0-MOUSE_BTN1 are mapped, the sequence of holding
down BTN0 and then BTN1 will redecide the current command. On the other
hand, if BTN0 is released before BTN1 is pressed, the command is
emitted, and the key history is deleted. So the BTN1 press will not
trigger BTN0-BTN1.

For normal keys, nothing should change, because commands are emitted on
the "down" event already, so the key history is always cleared.

Might fix #902.

-Introduction
-============
-
-This file lists all changes that can cause compatibility issues when using
-mpv through the client API (libmpv and ``client.h``). Since the client API
-interfaces to input handling (commands, properties) as well as command line
-options, this list is interesting for other uses of mpv, such as the Lua
-scripting interface, key bindings in ``input.rst``, or plain command line
-usage.
-
-Normally, changes to the C API that are incompatible to previous iterations
-receive a major version bump (i.e. the first version number is increased),
-while C API additions bump the minor version (i.e. the second number is
-increased). Changes to properties/commands/options may also lead to a minor
-version bump, in particular if they are incompatible.
-
-The version number is the same as used for MPV_CLIENT_API_VERSION (see
-``client.h`` how to convert between major/minor version numbers and the flat
-32 bit integer).
-
-Also, read the section ``Compatibility`` in ``client.h``.
-
-API changes
-===========
-
-::
-
- --- 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.
- 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)
- 1.1    - remap dvdnav:// to dvd://
-        - add "--cache-file", "--cache-file-size"
-        - add "--colormatrix-primaries" (and property)
-        - add "primaries" sub-field to image format properties
-        - add "playback-time" property
-        - extend the "--start" option; a leading "+", which was previously
-          insignificant is now significant
-        - add "cache-free" and "cache-used" properties
-        - OSX: the "coreaudio" AO spdif code is split into a separate AO
- --- mpv 0.4.0 is released ---
- 1.0    - the API is declared stable

-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)

-  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.
-- Decoder-dropped video frames, e.g. ``SD: 2``. Shows up only if the count is
-  not 0. Normally should never show up, unless ``--framedrop`` is set to enable
-  this mode, and your CPU is too slow. (``drop-frame-count`` property.)
-- VO-dropped video frames, e.g. ``D: 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

+- Change cache options to take kilobytes instead of percentages, and raise the
+  default values.
+- Lower --auto-pause/resume defaults values to improve web streams playback.
+- Use dvdnav support instead of the internal dvd implementation for dvd:// URLs
+  (the old implementation is available under dvdread://).
+- Rename some options to make them more consistent. Here's a partial list of
+  renamed options:

+- Re-introduce pretty-printing for module names with --msg-module.
+- Load Lua scripts under `$MPV_HOME/lua/` (default `~/.mpv/lua/`) automatically
+  (this can be disabled by using `--load-scripts=no`).
+- Corrupt/broken frames are not shown by default anymore (this can be re-enabled
+  by using --vd-lavc-show-all=yes).
+- Automatically copy metadata from the input file to the output when encoding
+  (this can be disabled by using --no-ometadata).
+- Change --sub-file semantics: if multiple --sub-file are used, the subtitle
+  tracks can be cycled at runtime and used with --sid and --secondary-sid.
+- Make the subtitle font size relative to the window, instead of the video, when
+  --sub-scale-with-window=yes is used.
+- Change default ao from wasapi to dsound on Windows.
 
 Bug fixes
 ---------
 
-- Correctly signal EOF when using --frames.
-- Strictly endorce the limit imposed by --frames (i.e. avoid producing an extra
-  frame at the end).
-- Fix \x-style escaping when parsing commands.
-- Correctly handle ^h key on the terminal (this should fix the when inserted
-  fromBackspace key on new versions of xterm).
-- Don't put the player to sleep after audio reinit.
-- Properly exit if both audio and video fail to initialize.

-Release 0.6.1
-=============
-
-Changes
--------
-
-- Don't show message on "osd" command by default (this essentially reverts a
-  change introduced in the last release).
-- Add an alternative input configuration that reverts the key binding changes
-  introduced by previous releases (see etc/restore-old-bindings.conf in the
-  sources).
-- Automatically install example input configuration files.
-
-Bug fixes
----------
-
-- Make stream language work with Bluray as well (the previous release
-  introduced this for DVDs, but it didn't work for Blurays).
-- Don't try to create surfaces of size 0 in the VDPAU vo.
-- Don't print audio/video init failure message twice.
-- Fix playback on the root window on X11 (i.e. when using --wid=0).
-- Fix the autodetection of the input format in the vf_stereo3d filter when mpv
-  is built against libav (this makes --video-stereo-mode work with libav as
-  well).
-- Fix compilation with PulseAudio 1.0.
-- Fix compilation with clang.
-- Try harder to decode cover art picture only once.
-- Fix cursor autohide (--cursor-autohide) with audio-only files on file change
-  (e.g. when skipping to the next playlist file).

-=============
-
-Changes
--------
-
-- Map ESC to exiting fullscreen.
-- Run the vo inside its own thread.
-- Enable the demuxer thread by default.
-- Prefer the opengl vo over the vdpau one.
-- Complete profile names in the zsh completion script.
-- Raise dsound ao buffer size to 200ms and make it configurable.
-- Bind ctrl+c to quit, so that it works both in the terminal and the player
-  window.
-- Automatically load playlists without needing --load-unsafe-playlists or
-  --playlist. Unsafe URLs are still rejected (e.g. remote playlists can't load
-  local files).
-- Remove quvi-format property (which never really worked).
-- Wait until all Lua scripts are loaded on start.
-- Use separate threads for input sources (terminal, lirc, joystick) instead of
-  using a central I/O loop.
-- Complete values for options that take file names in the zsh completion script.
-- Use libwaio for pipe input on Windows (if you want --input-file to work on
-  Windows you need libwaio as an additional dependency).
-- Remove the --volstep option (users should change the argument to the "add"
-  function in input.conf instead).
-- Always show the OSD message when changing volume, gamma, panscan, etc along
-  with the OSD bar.
-- When changing a property always show it on the OSD (except for "pause" and
-  "fullscreen").
-- Prefer the libavcodec decoder over libmpg123 for mp3 decoding (ffmpeg/libav
-  support for gapless audio works better for mpv's use-case).
-- Allow passing number of loops to --loop-file.
-- Change --keep-open option semantics to not terminate the player when playing
-  or seeking past the end of the file and there's no next file to be played.
-- Disable the sndio ao by default and prefer other outputs even if it's enabled.
+- Fix tv:// playback with missing timestamps.
+- Fix display of cover art inside audio files with the vdpau vo.
 
 New features
 ------------
 
-- Add new framedrop mode that limits the frequency of new video frames displayed
-  based on the display framerate (this is enabled by default, the old
-  decoder-based mode can be enabled with --framedrop=decoder).
-- Add --demuxer-readahead-secs option to control the readahead buffer using a
-  duration value.
-- Add estimated-frame-count and estimated-frame-number properties.
-- Add --cache-secs option which overrides the value of --demuxer-readahead-secs
-  if the stream cache is active.
-- Add demuxer-cache-duration and demuxer-cache-idle properties.
-- Make --cache-file create a temporary file if the string "TMP" is passed
-  instead of a file name.
-- Add support for Matroska 3D (if a file is marked as 3D using the StereoMode
-  element, an automatic conversion filter is added).
-- Add --osd-playing-msg option to show a message on the OSD when the playback
-  starts.
-- Add --media-title option to force the content of the media-title property.
-- Add --osd-msg1, --osd-msg2 and --osd-msg3 options to override the OSD message
-  for the corresponding OSD level (before only level 3 could be overridden with
-  --osd-status-message).
-- Add support for digital passthrough in the pulse ao.
-- Add support for opening DVD and Bluray directories directly.
-- Add --input-x11-keyboard option to control whether keyboard input should be
-  enabled on the X11 window ot not (this is disabled by default when using the
-  libmpv library).
+- Add client API in the form of the libmpv library, which is intended to be a
+  stable API to get some rough control over the player (this is not supported on
+  Mac OS X).
+- Add option for approximating BT.709 gamma for the opengl vo (similarly to many
+  programs in the Apple ecosystem).
+- Add support for non-BT.709 primaries.
+- Add support for BT.2020 colorspace.
+- Generate and install zsh completion script (disabled by default since it may
+  interfere with cross-compilation).
+- Add support for looping a single file (instead of the whole playlist) with the
+  --loop-file option.
+- Add VapourSynth video filter (this has various restrictions, which are listed
+  in the manpage).
+- Add support for ReplayGain in the volume audio filter.
+- Add a --config-dir option to force config directory.
+- Add support for GPU switching on Mac OS X.
+- Add support for automatic selection of color profiles on Mac OS X.
+- Add support for binding commands to sequences of keys.
+- Add support for passing options to Lua scripts with --lua-opts.
+- Add some filesystem utility functions to the Lua API.
+- Add functions for observing property changes to the Lua API .
+- Add support for creating a cache file on the filesystem with --cache-file.
+- Add support for window dragging by grabbing with the x11 vo.
+- Add option to write file name to watch later file.
+- Add support for a "weak" gapless mode, and make it default (the old mode can
+  be enabled with --gapless-audio or --gapless-audio=yes).
+- Automatically detect network filesystems on Linux and Windows.
