* Removal of support for dead platforms
* Generally improved MS Windows support (dealing with unicode filenames,
improved ``vo_direct3d``, improve window handling)
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``)
* 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 JPG, configurable filenames)
* Screenshot improvements (can save screenshots as JPG or PNG, configurable
filenames, support for taking screenshots with or without subtitles)
* Removal of teletext support
* Replace image VOs (``vo_jpeg`` etc.) with ``vo_image``
* Remove ``vo_gif89a``, ``vo_md5sum``, ``vo_yuv4mpeg`` (the plan is to merge
divverent's encoding branch, which provides support for all of these)
* 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. (Planned change.)
* Slave mode compatibility broken (see below)
* Encoding functionality (replacement for mencoder)
(Remove ``--vo=gif89a``, ``--vo=md5sum``, ``--vo=yuv4mpeg``, as encoding can
handle these use cases.)
* Image subtitles (DVDs etc.) are rendered in color and use more correct
positioning

mplayer. 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's hard to know just which messages are parsed by some
slave mode application, and as such it's virtually impossible to improve
intended for users. It's 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.

Features are a good thing, because they make users happy. As such, it is
attempted to preserve useful features as far as possible. But if a feature is
likely to be not used by many, and causes otherwise problems, it will be
likely to be not used by many, and causes problems otherwise, it will be
removed. Developers should not be burdened with fixing or cleaning up code that
has no actual use.
