Update to 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

    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).
